Machine Manufacturers 20 Ton Automatic Coal Heating Boiler

1.The crack of pipes and plates under high temperature can be prevented by using single backhaul solenoid,arch plate,aerofoil flue and elastomer shell taking the place of rigid shell.

2.The rational designed circulation loop prevents the base heating and bubbling. Backwater ejecting can improve the reliability of circular water,get rid of the pipes slagging and let the stove run orderly.

3.Good smoke prevention and dust control, the dust is inertial separated from the gas in the stove.

4.Small stove by optimize design and the price of boiler room can decrease 30%.

5.Good firing, it can add coal and slag remove automatically,so,it can save the stoker’s labor.
