SZL-type steam boiler is dual boiler cylinder portrait assembled water pipe boilers. The capacity of evaporation is 2 ~ 20t/h with the working pressure of 1.25 ~ 2.45MPa. This kind stream boiler is composed of upper and lower 2 main components, and the coal saver and air pre-heater are arranged at the rear part of the boiler; the combustion device uses center flexible grating; the smog after combustion shall have twice backhaul flushing transverse convection heat accepting surface and then induced into singly arranged coal saver and air pre-heater, and then exhaust from chimney through duster.

SZL-type steam boiler  features reasonable in structure, high in heat efficiency, low temperature in exhaustion; because of  the assembly structure and single storey arrange, the installation period is greatly shortened, the construction cost for boiler house is greatly reduced; simple in operation, safe and reliable in running, and convenient in maintenance.
