Main features:
1. Membrane water wall structure, front and rear arch, good sealability
2. Large volume and heating surface, high combustion efficiency
3. Light and large-size chain grates, straticulating combustion
4. Light boiler proper, saving transportation cost

Specific Design:
1. This product is double-drums vertical chain grate boiler, whose fuel is corncob blocks or bars. It's a high-efficiency energy-saving and environmental protection product.
2. The two sides of the furnace adopt membrane water-cooled wall structure. The tubes of water-cooled wall go down to the up side of the furnace,forming the front and rear arches so that the seal structure and intensity of back arch are enhanced and the cubic of the furnace and heating surface are enlarged.
3.There are end combustion chamber and convection tube tank in the back of the furnace with a fixing economizer in the rear. Through the furnace, end combustion chamber, convection tube tank and economizer, the flue gas comes into the flue duct in the rear, and then goes through dust precipitator, induced draft fan and chimney, and is discharged into the air in the end.
4. There is secondary air laid out in the front wall, which is controlled by valves and can be put into service to enhance the combustion and increase the combustion efficiency when biomass fuel is used as boiler fuel.
5. The height of feeding inlet is higher than usual to satisfy the need of biomass fuel.
