Steam boiler SZS series

hot watergas

SZS series oil steam boiler is designed and engineered with double drum, longitudinal layout, D type structure. The right side is the furnace, and the left side is the convection tube bundle. The superheater is arranged in the convection tube bundle, and is fixed on the body base via the movable support of the lower drum. The furnace is surrounded by a membrane water wall. The membrane water wall on the left side of the furnace separates the furnace and the convection tube bundle. The rear convection tube bundle is a shift structure, and the front is an in-line structure. The flue gas enters the reburning chamber and convection tube bundle from the outlet in the furnace tail, and then turns into the spiral finned tube economizer and condenser, and finally enters the flue duct and chimney. SZS series oil fired steam boiler is designed and optimized to produce low pressure steam or hot water with rated evaporation capacity from 4 to 75 ton/hour and rated pressure from 0.7 to 2.5MPa. The design heat efficiency is up to 95%. SZS series oil steam boiler can also be applied as oil hot water boiler for hot water generation and supply. Features of SZS Oil Steam Boiler The oil steam boiler is equipped with explosion-proof door and flame detector for safe and reliable operation. The combustion chamber of the SZS oil steam boiler adopts full membrane water wall structure, micro-positive pressure combustion, and has no pollution in the operating environment. Using high-quality aluminum silicate fiber and refractory cement, and the furnace temperature is below 45°C.
