The gas fired boiler adopts a fully wet back structure, and the high-temperature flue gas is surrounded by water, which solves the cooling and sealing problems of the return flue chamber and improves the operating environment of the boiler. The addition of the condenser (made of finned tube) increases the efficiency of the boiler to more than 98% and saves operating costs. The LNG steam boilers is equipped with a leakage protection function. Once the control system detects the leakage of the electric heating element, the boiler will automatically cut off the power supply to ensure the safety of workers and the boiler and improve the service life of the boiler.
The gas-fired steam boiler is a shell-type three-pass wet-back oil-fired and gas-fired boiler produced by advanced technology. This series of boilers consists of the boiler body, connecting flue, deaerator pump, deaerator, burner, steam and water system, instrument, energy saver, condenser, etc. Compared with the old boiler, its most prominent feature is low ammonia (during the operation of the boiler, the ammonia oxide emissions are greatly reduced, the minimum can reach 18mg/m”, which meets the specified policy requirements). In addition, this boiler has With its compact structure, beautiful appearance, simple operation, safe and reliable operation, it has been widely used in all walks of life.
The internal smoke pipe of the LNG steam boilers adopts a threaded structure, which improves the heat transfer efficiency and strengthens the heat transfer effect on the heating surface. The condenser is made of “sulfuric acid resistant and low dew point corrosion” special steel, which improves the service life of the boiler. This series of boilers are well-arranged to ensure the water circulation and thermal circulation, greatly improve the heat transfer effect, and achieve the best condition.
The combustion, water level, temperature and steam pressure of this type of gas boiler can be automatically adjusted and controlled automatically, which not only facilitates the operation of workers, but also improves safety. The WNS series steam boiler control system controls the start and stop of the circulating pump according to the boiler water temperature. When the boiler water temperature reaches the set upper limit, the hot water circulating pump starts, and when the water temperature falls below the set lower limit, the hot water circulating pump stops.
There is a condenser at the tail of the LNG steam boilers, which uses the waste heat discharged from the tail to increase the boiler’s inlet water temperature. In this way, the exhaust gas temperature is reduced, the thermal efficiency of the boiler reaches more than 100%, and the operating cost is saved. This series of boilers are widely used in food processing, printing and dyeing, pharmacy to provide production steam, medical institutions to provide disinfection steam, to provide steam for heating in other enterprises and hotels, and to provide domestic hot water through water tank heating.
