Steady state design theory to ensure various performances. The steady state design theory provides a theoretical basis for the structural design and performance calculation of the boiler. After the design according to the steady state theory, the layout of heating surfaces at all levels of the boile

Our corner tube boiler has a fully enclosed membrane wall structure, with good sealing and small air leakage coefficient of the boiler. The boiler body adopts the latest round furnace door. The furnace door is an embedded furnace door, which is welded with the membrane wall around. It has good seali

Tail heating surface:(1) Equal flow velocity variable cross-section design of the tail heating surface to ensure that the minimum smoke velocity of the flag heating surface is more than 6m/s.(2) The tail heating surface of each stage is reserved for soot blower interface and installation of soot blo

Design of membrane wall header without pipe joint. The membrane wall header without pipe joint design and installation site membrane wall piece inserted welding can reduce the pipe butt joint and flaw detection, and shortens the installation period.Horizontal water and fire tube boilers are also kno

The membrane water wall of the boiler adopts fully welded structure, which has good sealing and no air leakage, reduces the excess air coefficient of flue gas and reduces the loss q2 of flue gas; The heavy refractory brick and red brick wall structure used in traditional industrial boilers is change

The inlet and outlet flue of the waste heat boiler is provided with expansion joints to absorb the expansion of various components of the boiler. Moreover, the boiler body is equipped with expansion guide device to ensure the free expansion of the furnace body, limit the displacement and prevent the

The flue gas of waste heat boiler contains volatile sulfide and combustible materials, which will further complete the chemical reaction and release heat. Chemical reaction heat is fully considered in the design of waste heat boiler to meet the needs of production process. According to the flue temp

We have the manufacturing license of Class A boiler and Class A1 pressure vessel, ASME certification qualification, boiler installation, alteration, repair and maintenance license, and have passed IO9001 quality management system certification, ISO14001 environmental management system certification,

Sifang now has advanced drum production lines, header production lines, membrane wall production lines and serpentine pipe production lines, including CNC four roll bending machines, CNC blanking, large porous CNC drilling machines, CNC bevel machines, plasma cutting machines, various welding machin

The economizer and condenser adopt spiral fin tube and counter-flow arrangement to enhance heat transfer. The condenser is made of special ND steel with good cold resistance and corrosion resistance, which greatly improves the service life of the boiler. Reasonable flue structure and smoke box drain

Based on sophisticated oil-gas fired boilers production experience, our WNSL sries oil-gas fired boilers are used for ecological power generation through years of cooperation with famous domestic scientific research institutions and universities. Based on the operation data of the company’s existing

We have the manufacturing license of Class A boiler and Class A1 pressure vessel, ASME certification qualification, boiler installation, alteration, repair and maintenance license, and have passed IO9001 quality management system certification, ISO14001 environmental management system certification,
