horizontal SZL SeriesBiomass Boilers water-cooling arch and membrane water-cooling wall is a new type water tubes shop-assemble boiler.
horizontal SZL SeriesBiomass Boiler is shop assemble
water tube steam boiler.
horizontal SZL SeriesBiomass Boilers It is duble drums vertical chain grate boiler.
horizontal SZL SeriesBiomass Boilers The SZL Series 20 t/h Biomass Boiler type can be pure burning rice husk, no need to add additional material, emission of ash and slag can be directly used as a farmyard,
horizontal SZL SeriesBiomass Boilers it is a high-efficiency energy-saving and environmental protection products. The SZL Series 20 t/h Biomass Boiler type two sides of whose furnace adopt membrane water-cooled wall structure.
horizontal SZL SeriesBiomass Boilers The tubes of water-cooled wall go down to the up side of the furnace which forms 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.
horizontal SZL SeriesBiomass Boilers There are end combustion chamber and convection tube tank in the back of the furnace with fixing an economizer in the rear.
horizontal SZL SeriesBiomass Boilers After through the furnace, end combustion chamber, convection tube tank and economizer, the flue gas came into the flue duct in the rear, and then went by dust precipitator, induced draft fan &chimney, and was discharged into the air in the end.
horizontal SZL SeriesBiomass Boilers There is secondary air laying out in the front wall, which is controlled by valves and could be put into service to enhance the combustion and increase the combustion efficiency when using biomass fuel as boiler fuel. The height of feeding inlet is higher than usual to satisfy the need for biomass fuel.The main technical and economic indicators and data of SZL Series 20 t/h Biomass
