The drum is the most important pressure component in the boiler. It is a cylindrical container welded by steel plate. It consists of two parts: the cylinder and the head. Boilers are classified according to the type of drum, and can generally be divided into single-drum boilers and double-drum boilers. The dzl series biomass boiler produced by ZBG belongs to a single-drum boiler with only one upper drum.
Our DZL series water-fire tube boilers produced have the characteristics of low steel consumption, high thermal efficiency, strong overload capacity, good environmental protection effect, easy operation and maintenance, etc. The boiler is horizontal three pass chain grating boiler, which uses various biomass fuel. The boiler body is a single drum type, longitudinal arranged. There are left and right 2 rows of fire pipe bundles inside boiler cylinder to form convection heat receiving surfaces, the boiler cylinder and water cooling walls at both sides shape the furnace radiation heat receiving surfaces; the combustion equipment uses light chain grate
