If clean water is important to you and your family, you need to know about a silent danger to our waterways and public health.
Coal ash, the waste left over after coal is burned to generate power, contains concentrated amounts of heavy metals, such as lead, mercury, arsenic, chromium, and selenium, which are hazardous to human health, and to wildlife.
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. These systems are very energy intensive and also lead to excessive wear of pipeline and wastage of water.
Further, the present enhanced consciousness towards the imbalance in the eco-system and related stringent government policies are forcing the thermal power plants to adopt environment friendly transportation systems. Thus, high concentration slurry disposal (HCSD) system has emerged as preferred option to transport coal ash in thermal power plants as it is economical and environmentally friendly.
Concentration of 50% by weight was the limit of safe pumping of coal ash using a centrifugal pump and positive displacement pumps may become necessary to pump coal ash slurries above this concentration.
Here bellow we list some slurry pumps could do the work well
Ash&Ore Handling Slurry Pumps
Z 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 Single casing Slurry Pumps
D 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.
