Coal fired water tube boiler is double drums ,horizontal ,chain grate boiler .Boiler main parts contain upper part (boiler body) and lower part (chain grate).Boiler water circulation type is natural circulation .The main heating surface is boiler drum and boiler convection tube bundle .The boiler arch is made of refractory concrete ,boiler back arch is low and long ,so the combustion is good .Water tube boiler has large furnace and ensure fuel sufficient burning .Water circulates in boiler tubes heated externally by the fire ,quick heating ,can be used in large and medium-sized factories and power plants. Chain grate boiler is equipped with reasonable air distribution and for combustion chamber is large ,so fuel adaptibility is good for differents fuels. D type boiler can use air preheater and economizer to lower exhaust gas temperature ,so boiler thermal efficiecy can reach>90%. We offer automatic water treatment to get high quality water ,so can increase boiler working life .

  

Boiler Features :

1.Large diameter double drums increase the radiant heating surface,sufficient steam output and high thermal efficiency .

2.Membrane water wall construction.

3.For the good water circulation ,so enable a faster steam-raising and generation process .

  4.Equipped with air pre-heater ,use the waste heat of flue gas to heat the air ,decrease heat loss and improve the combustion condition.
