Roots Blower For Coal Fly Ash Pneumatic Conveying In Thermal Power Plants

With the rapid development of China’s power industry, large-scale thermal power plants have been built in various places. The problem of power plant waste discharge has become increasingly fierce. For example, the problem of fly ash emissions. A power plant with a total installed capacity of 1 million kilowatts, discharges about 120 tons of fly ash per hour. In this case, the annual emissions will reach 850,000 tons. (Roots Blower For Coal Fly Ash Pneumatic Conveying In Thermal Power Plants)

In the past, the power plant usually use wet drainage for the discharge of fly ash. That is water ashing. This not only consumes a lot of water resources but also occupies a large amount of land for stacking fly ash. what’s more, it pollutes the environment.

The smog problem is becoming more and more serious. So the treatment of industrial waste gas and industrial dust has become a problem we must solve. The way of hydraulic ash removal is obviously no longer suitable for the trend of social development. The use of the Roots blower delivery method is becoming more and more popular. It is environmentally friendly ash removal equipment.

There is no need to use water when using the Roots blower to convey the ash of the power plant. The ash is delivered in a closed environment,which does not pollute the environment. Thus it ensures that there will be no chemical changes in the transportation process and maintain the original characteristics of fly ash. This is conducive to the secondary comprehensive utilization of fly ash.


There are two types of conveying systems for the roots blower: high pressure conveying and low pressure conveying.

Due to the high cost, the high-pressure conveying is gradually replaced by the low-pressure conveying method. The Roots blower is suitable for power plant ash removal, cement homogenization, dumping, and transportation of various powder materials.

Advantages of using a Roots blower to transport fly ash:

1, Roots blower has good sealing performance without pollution and blockage, which can effectively improve the operating environment of the power plant.

2, Roots blower investment is small so as to reduce the total equipment investment.

3, It only needs a pressure rise of 1000mmaq—8000mmaq, which will reduce the gas supply consumption. At the same time, it also reduces motor power.

4, The maintenance of the Roots blower is easy. After installed and commissioned, it only needs to be checked regularly, and there is almost no maintenance in the later stage.
