SGB's slurry pump is widely used as ash handling pump in as handling system in power plant. Thermal power plants generate more than half of the world’s electric power by burning millions of tonnes of coal and simultaneously produce large quantity of coal ash. Slurry pipelines are commonly used across the world for the transportation of coal ash (fly ash and bottom ash) from the plant to the ash ponds in thermal power plants. Ash handling system mainly design for the collection, handling and disposal of bottom ash and fly ash from ESP System to Silo area and operation of its associated systems i.e. ash water, instrument air, conveying air and fluidizing air system. To increasing availability, increasing efficiency, and controlling emissions is a major requirement of the power industry today, and its importance will grow in the future.
The bottom ash resulting from the combustion of coal in the boiler shall fall into a W-type water impounded (water filled) ash storage hopper provided under the furnace bottom. The bottom ash hopper discharge gates shall be opened twice in a shift of eight (8) hrs. and the stored ash shall be removed by means of jet pumps and transported in slurry pipe lines to the ash slurry sump, integral in the ash slurry pump house for its further disposal to the dump area by means of ash slurry disposal pumps. Each section of the bottom ash hopper shall be provided with two (2) nos. ash gates, two (2) nos. clinker grinders and two (2) nos. jet pumps complete with feed gate housings. Only one set of equipment under each section shall be in operation during the ash removal operation, with the other set as standby.
ZJ series centrifugal slurry pumps suitable for handling abrasive and corrosive solids-bearing slurry with maximum concentrations of wt45%(ash) and wt 60%(ore). They are widely used in mining, metallurgy, power, coal, petroleum,chemical and building material sectors.
D series Slurry Pumps are innovative in hydraulic designs, structural designs and materials of castings after integrating congeneric products throughout the world. They have many features: high efficiency, reasonable design, reliable operation, long in service time, easy maintenance, and low running costs and so on.
