SZS Series Gas/Oil Fired Boiler Introduction

Digitized manufacture

  1. This series of gas/oil fired boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization;
  2. The explosion door and flame detector are equipped for safe and reliable operation;
  3. 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;
  4. Air proof test is done before delivery in the factory to guarantee any gas leakage problem.

 

Environment-friendly

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

 

Energy-saving

  1. 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.
  2. 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.
  3. Internal inspection holes uses high-alumina refractory and manhole cover seal devices, solving superheat problem in this part caused by using refractory bricks.

 

Convenience

Manholes are placed on the front and back side of drums and inspection doors on back side of boiler easy to open for inspection and clean inner and outer parts.

 

Longer working life

  1. Membrane structure are used in the front and back wall for boiler body and highly increased their lifespan to over 20 years.
  2. 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.
  3. Flutter prevention fastener is used for high temperature part convection tubes, which avoid convection tube cracking problem.
  4. Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will be tested by radiographic inspection.

 

SZS Series Gas/Oil Fired Boiler Advantage

  • SZS series gas/oil fired boiler adopts double-drum “D” type arrangement, compact structure, small floor space and good flame filling.
  • The furnace adopts the membrane type water wall structure, and the whole boiler adopts the airtight inner guard plate of the fully enclosed welded structure, and the furnace wall has good sealing performance.
  • The boiler layout has a large heating surface area and is designed with sufficient steam and water space to ensure stable boiler parameters.
  • The flue gas condensation recovery device is arranged at the tail to effectively control the exhaust gas temperature, and the boiler has high thermal efficiency.
  • High thermal resistance material is used as the thermal insulation layer, and the thermal insulation performance is good. The outer layer of the boiler is made of pressed guard plate, which is beautiful and beautiful.
  • Adopting the quick-loading structure, the whole boiler is designed on the base with strong rigidity, which is convenient for installation and transportation.
  • The furnace has inspection holes, which provides great convenience for use and maintenance. The top of the stove is equipped with an explosion-proof door.
  • Adopt automatic burner, continuous electric adjustment of water supply, high combustion efficiency. And with multiple protection functions, the operation is safe and reliable.
