SZS Series Water Tube Boiler Introduction

  • Model: SZS
  • Capacity: 7 – 116 MW
  • Design pressure: 1.0Mpa – 1.6Mpa(10 bar – 16 bar / )
  • Output water temperature: 115 – 130°C
  • Natural gas consumption: 720Nm3/h – 11880Nm3/h

SZS series oil gas fired water tube boiler adopts double-drum “D-type” vertical arrangement, full-membrane wall structure, reasonable and compact layout, can realize large-capacity boiler overall quick installation, less investment in boiler house infrastructure and short installation period.

szs oil gas steam boiler


  • 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.


  • Good quality alumina silicate fiber and fire clay insulation material are used and the boiler body temperature is controlled below 45℃ and greatly heat loss is reduced. Combustion chamber is designed with narrow distance tube membrane water cooling wall which has good air proof to reduce heat lost and increase boiler thermal efficiency.
  • Internal inspection holes uses high-alumina refractory and manhole cover seal devices, solving superheat problem in this part caused by using refractory bricks.
  • Longer working life

    • Membrane structure are used in the front and back wall for boiler body and highly increased their lifespan to over 20 years.
    • The key processes including material cutting, rolling, drilling are done by advanced CNC machining process to reduce the assembly stress and extend boiler service lifetime.
