SZS Series Condensing Fuel Oil and Gas Steam Boiler

The SZS series boiler adopts a longitudinal double-drum, D-type chamber combustion structure. The furnace is arranged on the right side, and the convection tube bank is on the left side. The boiler base is fixed by flexible supports installed at the middle and both ends of the lower drum, which can laterally fasten the entire boiler body.

Product Introduction

Narrow membrane water-cooling walls surround the furnace to achieve full sealing, and thermal compensation is realized between the membrane walls on the left front of the furnace and the convection tube bank. The boiler features an all-welded steel structure, with the front section forming the furnace structure. Flue gas generated from staged combustion flows out of the furnace’s rear outlet into the convection turnaround chamber, passes through the tube bank, turns at the front-left of the tube bank into the flue duct, and is finally discharged to the atmosphere via the chimney.
