SZS series gas-fired (oil-fired) hot water boiler

Product introduction

SZS series boiler is designed with longitudinal double drums and " D " type chamber structure. The furnace is on the right and convection tube bank is on the left. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane wall. Furnace and tube bundle are totally separated by the membrane wall at the left side of the furnace. The back part of convection tube bank is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, convection tube bank area, and then from left front part enters spiral fin coil economizer and condenser, and finally is discharged to atmosphere through chimney.


Product thermal capacity : 7-70 MW

Working pressure : 1.0-1.6 Mpa

Digitized manufacture

Boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization; The explosion door and flame detector are equipped for safe and reliable operation. Comb plates are used between both sides of boiler and tube bundle to avoid leakage of condensate and gas caused by using refractory concrete as sealing material. Air proof test is done before delivery in the factory to guarantee any gas leakage problem.

Environment-friendly

Big combustion chamber equipped with Low emission combustion burner effectively reduce the NOx to 30mg/m3. Smoke duct and smoke outlet use internal insulation to reduce operating noise.Combustion chamber uses full membrane water cooling wall structure and pressurized combustion without smoke mixture.
