Product Introduction and Feature

The SZS water tube gas fired steam boiler adopts a double-drum vertical D-type furnace structure, with energy-saving devices placed at the tail for additional heating surface. 

The burner is arranged on the front wall, and the convection tube bundles are placed parallel to the furnace. The combustion gases pass through the rear of the furnace and 

flow successively through the heater (if present), convection tube bundles, and the rear heating surface before being discharged into the atmosphere through the chimney.
