CONTROL VALVES

Function

Process plants consist of hundreds, or even thousands, of control loops all networked together to produce a product to be offered for sale. Each of these control loops is designed to keep some important process variable such as pressure, flow, level, temperature, etc. within a required operating range to ensure the quality of the end product.

$E:\MINECO\WEBSITE_MINECO\5_POWER INDUSTRY_08 pages\Control valve-01page\Capture2.JPG$

The control valve is a critical part of the control loop. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds to compensate for the load disturbance and keeps the regulated process variable as close as possible to the desired set point.

Control Valve Arrangement

The image below shows how a control valve can be used to control rate of flow in a line. The “controller” receives the pressure signals, compares them with pressure drop for the desired flow and if the actual flow is different, adjusts the control valve to increase or decrease the flow. Comparable arrangements can be devised to control any of numerous process variables. Temperature, pressure, level and flow rate are the most common controlled variables.

BOILER TUBES

XID, or X-ID boiler technology refers to internally augmented boiler tubes that feature helical ribs embossed on the inside of the tube to provide increased surface area and increased heat transfer for gas flowing inside the tube of a firetube boiler. These internal spiral ribs cause a complex boundary layer separation and reattachment phenomenon. The combined depth of tubing wall and ribbing is above minimum wall specifications and delivers a tested inside transfer rate of up to 85% greater than plain tube.

$E:\MINECO\WEBSITE_MINECO\5_POWER INDUSTRY_08 pages\Boiler tube-01page\600600p739EDNmain64XID-tubing.jpg$

The design of the tube gives it more “heating surface” than a standard tube and transfers more heat into the water from the hot flue gas as well. Because XID tubes add more heating surface and transfer more heat, they reduce the need for additional heating surface of the overall boiler. This allows a smaller physical foot print, ideal where space is limited.

$E:\MINECO\WEBSITE_MINECO\5_POWER INDUSTRY_08 pages\Boiler tube-01page\Capture7.JPG$

As X-ID boiler tube technology improves transferring the heat content of the fuel into the boiler water, more heat can be absorbed to the lower the flue gas temperature and produce greater operating efficiency (the ratio of heat output against heat input). Case studies have shown that XID tubes can add additional 4%+ to boiler fuel efficiency.

In addition to greater efficiency, other key benefits include:

■ up to a 20% cost savings over bare tube designs

■ increases steam-volume capacity

■ improves steam quality

■ reduces space requirements (footprint)

■ reduces fuel consumption

■ lowers NOx emissions

ECONOMIZERS

Economizers (as well as air heaters) perform a key function in providing high overall boiler thermal efficiency by recovering low level (i.e., low temperature) energy from the flue gas. For each 40F (22C) that the flue gas is cooled by an economizer or air heater in a conventional boiler with air as the oxidant and normal excess air, the overall boiler efficiency typically increases by approximately 1%.

$E:\MINECO\WEBSITE_MINECO\5_POWER INDUSTRY_08 pages\Boiler tube-01page\Capture2.JPG$

IN-LINE “H” FIN DESIGNS OFFER COUNTLESS BENEFITS

■ Particularly effective in applications with dust-laden flue gas

■ Reduces turbulence and fouling of tubes

■ Typically reduces gas velocities and tube erosion rates

$E:\MINECO\WEBSITE_MINECO\5_POWER INDUSTRY_08 pages\Boiler tube-01page\Capture.JPG$

■ Offers the ability to vary fin spacing along the same tube to suit different ash burdens from front to back of the backpass

■ Provides a more compact design with reduced pressure drop versus existing bare tube designs

COMBINED FLOTATION CELLS

By combining Wemco® self aspirated and Dorr-Oliver® forced air cells in the same plant FLSmidth can exploit their unique characteristics to maximize circuit and row performance.

In the past, mineral producers had to choose between mechanical flotation systems that naturally ingest ambient air and others that require a blower. FLSmidth is in the unique position to exploit the inherent and unique advantages of both the Wemco® self aspirated and Dorr-Oliver® forced air technologies. These two types of machines can be used in different parts of the flotation circuit forming a Mixed Circuit™ or in a single row forming a Mixed Row™.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\Mixed rows and Mixed circuits\Capture.JPG$

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\flotation pictures\mixedROW-Flotation-System.jpg$

Mixed Circuits™:

Wemco for Recovery & Dorr-Oliver for Cleaners The Wemco design with its agitator near the top of the tank maximizes coarse particle recovery since transport distance of the fragile bubble particle aggregate is minimized. The Wemco mechanism is also not exposed to the damaging effects of tramp material (ball chips etc) that are inevitable in rougher circuits due to upsets. The Wemco cell is a true workhorse for rougher, rougher scavenger and cleaner scavenger applications.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\flotation pictures\Portfolio_227.jpg$

The Dorr-Oliver design with its rotor/stator at the bottom of the tank is well suited for maximizing air dispersion and focusing energy dissipation, conditions which drive fine particle flotation. The fine particles can survive the higher transport distances inherent in this design. This distance also serves to promote upgrading making the Dorr-Oliver machine ideally suited for cleaner applications. Air control and higher range of froth depth with the Dorr-Oliver design also are beneficial in the cleaner application. The FLSmidth Mixed Circuit™ is an exceptional and unique flotation solution to optimize your flotation plant performance.

Mixed Rows™:

Maximizing recovery by combining Wemco and Dorr-Oliver Mechanisms in the Same Row The Mixed Row is an extension of the Mixed Circuit concept. By combining the inherently different designs in the same row it is possible to exploit their unique advantages further to maximize recovery. There are several strategies which have been employed in several plants around the world. These are tailored to the particular application and can offer greatest flexibility for optimized recovery.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\Mixed rows and Mixed circuits\Capture4.JPG$

The Universal Tank

On large cells (100m3 and larger), we have developed a “Universal Tank” that can accommodate either the Wemco induced-air cell or the Dorr-Oliver forced-air cell and are interchangeable to provide flexibility for future ore changes or other considerations. By supplying customized solutions to its mineral processing partners, FLSmidth maintains its global industry leadership in the supply of flotation technology with over 53,000 flotation cells delivered to date.

Dorr-Oliver^® Flotation Cells

While excellent as an “all around flexible” flotation machine the Dorr-Oliver design is well suited for fine particle recovery with multiple high energy contacts and high bubble surface area flux

Increased Fine Particle Recovery

The Dorr-Oliver Flotation Mechanism is the most energy efficient, technically advanced, forced air flotation machine on the market. It has been specifically designed to maximize fine particle recovery.

The Dorr-Oliver streamlined, high efficiency rotor is a very powerful pump that works together with the stator to generate and define an energy intensive zone in the bottom of the cell. This ensures effective solids suspension and the ability to restart in even the most difficult of applications.

The well defined turbulence zone at the bottom of the cell results in multiple passes of unattached particles through the highest energy dissipation area of the cell where fine particles are driven into contact with the air bubbles.

The stator design, in addition to providing good separation of the zones in the cell also serves to redirect the rotor jet uniformly across the tank to allow the maximum amount of air to be dispersed into the cell without disturbing the surface. Air dispersion capabilities of the Dorr-Oliver cell exceed all competitive forced air designs. Maximizing the air dispersion capability is an important consideration for fine particle recovery.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\flotation pictures\dorr-oliver2.JPG$

Improved Froth Handling and High

Concentrate Grade By containing the intense circulation energy at the bottom of the cell the upper zones of the cell remain quiescent to maximize recovery of marginally attached coarse particles and minimize entrainment. The Dorr-Oliver Cell is an exceptional design for cleaner duty.

Dorr-Oliver tank cells are equipped with a uniquely designed high efficiency radial launder system that accelerates the removal of froth as it reaches the surface. Bubble–particle aggregates travel vertically through the froth lattice in essentially plug flow while upgrading. The high efficiency radial launder is shaped to receive the froth uniformly from the cell surface as well as from the typically heavy loaded area near the center of a forced air machine. On passing over the lip the froth is accelerated to the perimeter of the cell. Rarely is launder water a requirement with this unique design.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\2. Forced Air Flotation Cells\Capture9.JPG$

- Well defined quiescence zone reduces entrainment and gives stable froth
- Concentrate grade is maximized.
- High efficiency radial launder maximizes froth recovery and reduces coarse particle drop back.
- Froth transport is optimized.

SuperCell® Flotation Cells

FLSmidth is pioneering the way for large cell technology with the largest operating cells on the market today. From our first 250m3 cells installed in 2003 to now with up to 350m3 designs and 300m3 cells being installed around the world.

The 350m3 SuperCell™ flotation cell is the largest operating flotation cell in the world with proven performance in hydrodynamics, metallurgy, and mechanical reliability.

FLSmidth has the largest installed based of large cells around the world.

Over 50 of the 300m3 SuperCells have been sold and over 100 of the 250m3 cells have been installed.

The SuperCell Flotation Cells are proven to reduce operating and installation costs as a result of the economies of scale and a reduced foot print with fewer control points.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\flotation pictures\62016-7282355.jpg$

Scale up was completed using validated CFD models with comprehensive metallurgical testing at full scale. There is no degradation of metallurgical performance with the SuperCell.

SuperCell benefits include:

- Reduced foot print
- Reduced installation cost
- Easier implementation of sophisticated process control
- Equal or better metallurgy
- Proven performance in hydrodynamics, metallurgy, and mechanical reliability

FLSmidth SuperCells use a universal tank that can be fitted with either the Wemco® self aspirated or Dorr-Oliver® forced air designs. This allows SuperCells to be installed as roughers, cleaners and scavengers depending on the requirements of your application.

Taking forced-air flotation to the NEXT STEP

FLSmidth’s nextSTEP™ rotor/stator provides a step change in metallurgical performance and energy efficiency compared to any other forced-air design on the market.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\2. Forced Air Flotation Cells\Capture.JPG$

Innovative technology

FLSmidth introduces the patented nextSTEP™ advanced flotation mechanism; the newest design for forced-air flotation technology which reduces operating costs with the lowest power consumption on the market. This new rotor/stator technology is the result of extensive fundamental studies, laboratory test work and full-scale plant testing.

$E:\MINECO\WEBSITE_MINECO\Page 2_Flotation\flotation pictures\Portfolio_236.jpg$

FLSmidth has proven to be the market leader in providing new technology for mineral processing, particularly top-of-the-line flotation equipment. Continuous improvement and development of new products demonstrates FLSmidth’s strong commitment to the minerals market and its customers.

FLSmidth spent four years developing nextSTEP, starting from first principles, using computational fluid dynamic models, and 3D printed prototypes, to optimize the rotor-stator design.

This final technology demonstrates significant improvement in both metallurgical performance and energy efficiency over existing forced-air designs.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\2. Forced Air Flotation Cells\Capture5.JPG$

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\2. Forced Air Flotation Cells\Capture6.JPG$

CFD Comparison of the turbulence eddy dissipation for stators with and without slots. Slots yield more homogenized turbulence dissipation.

The exceptional performance of the nextSTEP mechanism comes from the rotor and stator being perfectly matched which delivers the best energy dissipation flow, thus maximizing recovery.

The superior metallurgical performance of the nextSTEP mechanism shows up to a 5% increase in recovery, resulting from dramatic improvements in mineral-bubble attachment rates.

When installed, operators note a 15-40% reduction of power requirements and see better wear distribution for increased rotor/ stator life. These findings have a strong positive impact on total cost of ownership that can benefit both new and existing installations.

Increased flotation

Wide flow jets produced by the nextSTEP rotor and the cross pattern from the patented slotted nextSTEP stator increase the probability of bubble-particle attachment. Adding slots to the stator increases recovery and boosts overall flotation efficiency. One reason for this improvement is the higher homogenized turbulence dissipation energy.

Superior metallurgical performance

In-plant testing of the nextSTEP rotor/ stator combination showed superior metallurgical performance compared to a non-slotted stator design. These results showed dramatic improvement in the attachment rate from the slotted stator design which translates into statistically significant recovery increases.

Improved recovery of coarse particles

When compared to other forced-air flotation designs, the nextSTEP mechanism exhibits stronger air dispersion near the rotor/stator region, higher air hold-up and a stronger pumping effect below the rotor. CFD analysis shows that the nextSTEP mechanism generates a preferred slurry flow and positive froth movement pattern near the top of the tank. This improves froth mobility and recovery of coarse particles over other competitive designs.

Better mixing

Solids suspension tests performed in laboratory, pilot and full-scale conditions exhibited excellent mixing over a wide range of impeller speeds.

Wide flow jets produced by the nextSTEP rotor and the cross pattern from the patented slotted nextSTEP stator increase the chances of flotation

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\2. Forced Air Flotation Cells\Capture8.JPG$

Lowest power consumption on the market

The nextSTEP mechanism demonstrates a significant decrease in power consumption in comparison to other flotation technologies and has proven to be the lowest energy flotation mechanism on the market.

The lower energy consumption and the superior metallurgical performance of the nextSTEP mechanism is beneficial for any operation. The nextSTEP mechanism has a strong positive impact on long- term operating costs for greenfield projects. In the case of brownfield projects and existing concentrators, the mechanism is interchangeable with existing FLSmidth forced-air flotation mechanisms and can be retrofitted to all mechanical forced air flotation machines, regardless of make or model.

$E:\MINECO\WEBSITE_MINECO\3_FLOTATION MACHINES_03 pages\flotation pictures\Capture20.JPG$

Converting to nextSTEP is simple and low risk. The existing mechanism assembly is utilised. Rotor and stator are attached with adaptor flange and baseplate respectively, and drive sheaves replaced to optimise speed. The FLSmidth conversion process is thorough and proven – with a large number of successful retrofits already for flotation cells ranging in size for 1.7m3 to 250m3.

Increased wear life

Several tests performed on the nextSTEP rotor/stator showed a more even wear distribution than other available mechanisms. This increases the life cycle of the mechanism as there are no heavy wear spots during operation. This not only saves money over the life of the rotor/stator, but reduces downtime for repairs or replacements. In addition to even wear patterns, the rotor can be run in a reverse direction to further increase the life cycle of the mechanism.

duraMAX™ PERFECT SLURRY PUMP FOR HIGH HEAD APPLICATIONS

duraMAX centrifugal slurry pump to provide clear passage of large solids, and to minimise shearing, solids degradation, air locking and wear.

Our duraMAX pump, with its large internal clearances and superior hydraulic design, maintains the integrity of the product by delicately handling solids in suspension.

The duraMAX reduces carbon attrition and shear stress making it an ideal choice for the carbon transfer process.

Suitable for all industries where tramp material, product degradation, and entrained air can affect pump performance.

$E:\MINECO\WEBSITE_MINECO\2_SLURRY PUMPS_03 pages\3-High Head Pump\Capture6.JPG$

$E:\MINECO\WEBSITE_MINECO\2_SLURRY PUMPS_03 pages\3-High Head Pump\Capture3.JPG$ In applications such as flotation, concentrate slurries will have a significant amount of entrained air known as froth. When pumping froth slurry, special considerations must be taken since it will no longer perform as normal slurry at the same pump speed.

The difference is due to the air, which expands in the low-pressure zone at the eye of the impeller and inhibits the flow going through the pump. Traditionally, pumps are oversized to account for the volume of air at the eye of the impeller so that they still generate the required flow rate.

Oversizing, however, is not the only solution! With a recessed impeller design, the duraMAX allows for the clear passage of air entrained slurries without influencing the duty flow and head. Through constant recirculation, the open vortex impeller design allows for froth advancement without air locking. In fact, the duraMAX can handle slurries containing up to 30% entrained air.

PRODUCT FEATURES

Unique features drive the duraMAX pump’s powerful performance

$E:\MINECO\WEBSITE_MINECO\2_SLURRY PUMPS_03 pages\3-High Head Pump\High head pump-EN6.JPG$

The duraMAX centrifugal slurry pump is designed to provide safe passage of large solids without clogging and without shearing or degrading the product. Even at low flows, the duraMAX provides performance that cannot be reached by many centrifugal pumps.

Our duraMAX pump is the longest-wearing and most efficient pump in its class. It features a heavy-duty concentric casing design that reduces radial loads and extends bearing life. The recessed impeller and concentric casing provide large internal clearances that allow for the clear passage of large solids and reliable operation at low flows.

Our duraMAX pump is available in sizes ranging from 80 mm x 50 mm (3-inch x 2-inch) to 250 mm x 200 mm (10-inch x 8-inch).

KEY BENEFITS

The duraMAX preserves your product and prevents air locking

$E:\MINECO\WEBSITE_MINECO\2_SLURRY PUMPS_03 pages\3-High Head Pump\High head pump-EN4.JPG$

Minimized product degradation and shearing

The duraMAX’s concentric casing and recessed impeller design create large internal clearances that allow for clear passage of solids without contacting the impeller – reducing the chance of product degradation and shearing.

Reduced risk of air locking

The duraMAX is designed to reliably pump slurries with up to 30% entrained air without air locking. Through constant recirculation, the bubble at the impeller eye is broken up, increasing efficiency, reducing power draw and minimising flow instability, even in flotation applications and low-level sump operations.

$E:\MINECO\WEBSITE_MINECO\2_SLURRY PUMPS_03 pages\3-High Head Pump\Capture.JPG$

Large solids passing size

The duraMAX is designed to provide safe passage of large, shear-sensitive solids without clogging and without degrading the product.

Extended wear life

The heavy-duty concentric casing design eliminates radial loads, which greatly extends the life of the pump, the seals and the bearings.
