ZOZEN SZS series oil gas fired boiler  ZOZEN SZS series oil gas hot water boiler

SZS boiler body is the structure of longitudinal double drums and D-type chamber combustion. The furnace is on right side and the convection tube bundle are on left side. The flexible supports of boiler are in the middle and two ends of the lower drum, and it can secure the whole boiler body to expand sideways. There are narrow-space membrane cooling tube walls on the four sides of furnace. The left membrane wall makes the furnace and the convection tube bundle separated. The rear of convection tube bundle is a kind of tube-decreasing and staggered structure, and the front is an aligned structure. The flue gas generated from furnace combustion flows from the rear outlet of furnace into the end of combustion chamber, convection tube bundle area, and then turns from the front-left of furnace to the spiral finned tube economizer, and next flows into smoke duct and chimney and finally exhausts into atmosphere.
