Abrasion resistant fiberglass pipe was chosen to move the limestone slurry within the system. The lime slurry is finely distributed by rotary atomizers or nozzles into the flue gas.

Valve Selection For Lime Slurry Service Pumps Systems

Full Slurry Pipeline Assignment Slurry Pipeline Data for C d vs.

. Together well scope define and refine your piping specs. China coal briquette machine supplier charcoal briquette machine shisha we have become to a factory including design manufacture sale and after-sales service. There is a newer edition of this standard available.

Unless noted on design drawings this specification does not apply to buried piping. The return line will take the 2X flow back to the tank. A straight line from tank to pump is preferred.

Pinch valves are an efficient solution for lime slurry service because they have a straight-through design with no crevices or cavities for material collection. Ad Ideal for Transporting Ore Minerals Water and Other Fluids. Scaling in lime slurry piping is another problem caused by the escape of air into pipes formation of calcium carbonate and settling of solids during off cycles especially when smaller diameter slurry lines are used.

Shavings drying machine airflow pipe wood sawdust dryer price for sale energy saving wet fertilizer river sand coal slurry chicken manure. Mechanically the design of the lime-slurry spraying equipment is important. C d R p2 in Excel The limestone is crushed at the quarry mixed with water to form a slurry and pumped through the pipe.

315 Lemay Ferry Rd Suite 129 St. Scaling in lime slurry piping is caused by the leakage of air into pipes which leads to formation of calcium carbonate and settling of solids during off cycles. I normally use an actuated plug or ball valve to pulse the lime feed into the reactorclarifier.

Get in touch and tell us about the piping specification challenges youre dealing with. 22001 Piping systems are not subject to the approval of TSSA Boilers and. Lime slurry is a stable suspension and is not corrosive once the slurry has been stabilized by allowing all of the water to fully react with the calcium hydroxide usually about 15 minutes minimumthe dissolved solids from the dilution water will precipitate if injected before stabilization on piping and injectors and form scale.

WEIR SLURRY PUMPING MANUAL iv1 Symbols used The terms slurry and mixture in this Manual are used interchangeably to describe a mix of any loose solids made up in any proportions and combinations of any particle sizes and any conveying liquidThe subscript w refers to densities and specific gravities of liquids mostly but not exclusively water. Section 1249 Piping System Design states Good slurry sump design should be aimed at preventing uneven flow into the pump suction while providing for transportation of pumped solids to the pump suctionThe main geometrical. Use of small diameter slurry lines aggravates this problem Cleaning of scale in pipes can be very labor intensive particularly in metal pipes where cleanouts are not provided.

Lime slurry is a suspension of calcium hydroxide solid particles floating in water and due to the low solubility of calcium hydroxide only a small portion of it is dissolved at any given time in the slurry. Slurry pumps should also be considered a generic term to distinguish them from other centrifugal pumps mainly intended for clear liquids. Lime Slurry - Up to 150 PSIG Design Conditions 150 PSIG 149o F Operating Conditions Atmospheric - 125 PSIG 110o F Design Fabrication Installation Approval Requirements ASME B311 Power Piping OReg.

Make sure you step the pipe size down on the return line. However there have been significant refinements to detailed hydraulic design. As the slurry mixed with hot flue gas some water is evaporated.

Steel piping systems are widely used at coal-fired power plants for a variety of purposes including the conveyance of coal ash slurry to nearby settling ponds the transfer of limestone slurry to. In most cases the strategy is to make a settling slurry into a non-settling slurry so that it can be treated as a normal homogeneous fluid. Inlet Design Hydraulic Institute 121126- -2005 deals with the design and operation of centrifugal slurry pumps.

Tell us what you need. Choose the right solution. Slurry storage tanks with agitators Slurry pumping system to kilns.

A rotating atomiser is used situated in the top of the spray-dry chamber. Of pump the design of the pipe system etc you can always contact your flygt support for advice. 5 Slurry pumps Slurry pumps are a heavy and robust version of centrifugal pumps capable of handling tough and abrasive duties.

Slurry storage tanks with agitators Slurry pumping system to kilns St. After some time in operation it was determined that there were areas of high wear in one of the 8 inch fiberglass pipe lines at some of the elbow locations. 2 DESIGN WITH KEY PARAMETERS The determination of hydraulic gradient head loss per unit distance is essential for designing slurry pipelines.

You will want the. The remainder water in the sorbent promotes the reaction with SO2. How our slurry piping specification review process works.

Needless to say cleaning scale in pipes can be very labor intensive particularly in metal pipes. Lime slurry is a stable suspension and is not corrosive once the slurry has been stabilized by allowing all of the water to fully react with the calcium hydroxide usually about 15 minutes minimumThe dissolved solids from the dilution water will precipitate if injected before stabilization on piping and injectors and form scale. Design a pipeline for transporting crushed limestone from a quarry to a terminal located some distance away using water as a transporting medium.

Immediately downstream of the plug valve is a manual pinch valve that you use to adjust the lime slurry feed rate. Every change of direction adds friction losses to the flow. This resulting product is known as lime slurry milk of lime or by product brand names such as CALSAFE.

Lime slurry piping designsawdust briquette machine for sale. I have also seen a half pipe. Design the inlet piping to be as short as possible between the sump and pump.

We guide you through our collaborative workshop process. Pinch valves have a proficient self-cleaning effect on scaling materials. A rubber tube or sleeve is pinched by steel bars on the centerline of the valve causing it to close.

Maintain the inlet line in as straight a run of piping as possible. This Code prescribes requirements for the design materials construction assembly inspection testing operation and maintenance of piping transporting aqueous slurries of nonhazardous materials such as coal mineral ores concentrates and other solid materials. The limestone is abrasive and requires an abrasive resistant piping system.

A schematic of Lime Spray Dryer LSD with optional Furnace Sorbent Injection FSI is shown in Fig. System designed to pump lime slurry to several kilns for sulphur mitigation in flue gas discharge Pneumatic system conveying lime from nearby plant to skirted storage silo containing slurry mixing equipment. The principles of good slurry pipeline design suspension and handling have been well defined since the early 1950s.
