SZL6-1.25-WIII coal-fired steam boiler is a double-drums shop assembled chain grate boiler, rated evaporation 6t/h, rated steam pressure 1.25MPa. The steam temperature is saturated temperature and the fuel is anthracite Class III. The water cooling wall is set in three sides of the furnace and combustion chamber and convection tubes is set behind the after-combustion chamber. At the rear, there are cast iron economizer and air-preheater. The exhaust gas passes the furnace, after-combustion chamber, convection tubes, economizer, air-preheater and goes into the rear flue, and then passes the dust remover, ID fan, chimney and goes into the air.

Double-drum coal fired steam boiler structure

The boiler leaves the factory in two parts: the upper part includes the boiler proper, upper steel frame and upper furnace wall and the lower part includes coal bucket, chain grate, lower furnace wall and inner ventilating duct. Except the front and back arch and part of the brick walls are installed at site, the remaining parts all leave the factory in shop assembled form. The rear matching economizer, air-preheater and ventilating duct leave the factory together with the boiler.
