WNS series gas boilers are energy-saving boilers with shell type, corrugated furnace and threaded smoke tubes. They adopt a three-pass wet-back structure. The fuel is burned in the furnace to produce high-temperature flue gas. It passes through the backfire chamber, the first convection tube bundle, The front smoke box, the second convection tube bundle, the rear smoke box, the normal pressure condenser, and the rear exhaust of the chimney.
Corner tube boilers use boiler coal injection technology. After the fuel is ejected in the hot air, it goes through multiple links such as ignition, combustion, coal ash separation, re-contact and combustion, etc. to generate flue gases that enter the boiler. The flue gases are exchanged with each other through water pipes and superheated pipes. After heat transfer, it turns into water vapor and enters the steam turbine to generate electricity. Because the corner tube boiler fully contacts the hot air and the combustion material, the heat energy is maximized, so it has the advantages of high thermal efficiency, energy saving, and environmental protection.
The high-efficiency and energy-saving furnace is a corrugated furnace. The furnace, backburner chamber, and front and rear tube plates all adopt a full edge structure, which can effectively eliminate the thermal stress of the furnace.

The boiler water is only used as a heat carrier. During operation, the oxygen in the water is heated and precipitated. It is discharged out of the furnace. Oxygen corrosion will not occur in the furnace for long-term use. When the heat medium water is added at one time, a limited amount of calcium and magnesium ions are also heated and softened. The furnace water does not increase or decrease during operation, so no scaling occurs inside the boiler, which prolongs the operation. The service life of the boiler is 1.5 to 2 times that of ordinary boilers.
