There are end combustion chamber and convection tube tank in the back of the furnace with fixing an economizer in the rear. 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. 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.
