Steam, Hot Water Boiler

Series of DZL type is horizontal tri-backhaul water fire pipes chain grating quick installed boilers, with the evaporation capacity of 2t/h, 4t/h and working pressure of 1.0 - 2.45MPa. The boiler body frame is singly boiler cylinder portrait type, the length of boiler cylinder and chain grating are extended; appropriate rear arch is arranged to let a rear arch coverage reach 70%; there is air pre-heater at the rear part; the combustion device uses center flexible grating, equipped with bigger blower and induced draft fan. This series of boiler features compact in structure, small in overall dimensions, new technologies of arch pipe and plate abnormal shaped flue and helix smog pipe, high in heat efficiency, safe and reliable in running, and convenient in transportation and installation.Series of SZL type is dual boiler cylinder portrait assembled water pipe boilers. The capacity of evaporation is 6 ~ 20t/h with the working pressure of 1.25 ~ 2.45MPa. The 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. This series of 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.
