Measures to reduce the coal fired boiler heat losses

ZG boiler is a eminent manufacturer of industrial boiler China, and we provide good quality coal fired boilers to our clients. But heat losses might occur, the followings are some measures to help reduce coal fired boiler heat losses.

Choosing the appropriate coal

The quality of coal has a grate influence on the service life of coal fired boiler,the proper coal includes the following aspects:the ash content of coal is not less than 6%,the ash melting point should be over 1250 ℃, the coal particle size should be moderate,the detritus content below 3mm is not more than 30%, the largest particle should not exceed 40mm.

The reasonable layout of furnace

In order to reduce the combustion loss,the full combustion of fuel is needed,which can be achieved by strengthening the mix and stir of space air,it is completed by the cooperation of front and rear arches and the secondary air.

The reasonable air distribution

The air is indispensable to ensure combustion,the reasonable air distribution makes a great difference to the energy conservation of coal-fired boiler,the air should also be reasonably distributed along the grate length and width direction.For example,ZG coal-fired boiler adopts the way of air inlet in both sides,longitudinally arranges six air chambers along the grate,each air chamber has air regulating devices to adjust the air volume,which can achieve the best effect of adjusting the combustion.
we have the project of 10 ton coal boiler to Vietnam
