DZL series coal biomass fired boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. This furnace structure in reasonable arrangement and high efficiency. This series boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.

FAQ of coal fired steam boiler
1. What are the limitation (size, humidity, chemical element concentrations) of coal fuel/solid fuel/wood fuel?
Size requirement of coal:6-25mm
Size requirement of blending coal:<50mm (the coal less than 6mm should less than 30%)
Diameter of biomass particle: 6~10mm, length: 25~50mm, water content < 15%, ash content < 2%, sulphur content<0.07%, chlorinity <0.07%, nitrogen content < 0.5%
2. What is the combustion mode of coal/biomass fired boiler?
The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.
3. What is the height of chimney?
The chimney is usually 30m, irrespective of the special circumstances.
4. What are the heat-resistance temperature of grate and furnace?
The heat resistance temperature of grate is related to the grate material, the highest temperature could be as high as 1200℃, and the lower temperature could be 700℃.
The highest heat resistance temperature of furnace could be about 1700℃~1800℃.
5. What is the temperature of smoke gas?
The highest temperature of smoke gas is 165℃.
6. How long can the coal/biomass fired boiler works?
Coal/biomass boilers could work for 10~15 years, under correct operation, high water and coal quality, etc.
