Everyone knows that some nitrogen oxides can cause harm to the human body. Therefore, low nitrogen is what everyone is pursuing. After continuous research, ZOZEN’S has developed a WNS type low-nitrogen gas fired boiler with a nitrogen and oxygen emission of 30mg/m3 or less. This boiler can not only meet the requirements of environmental protection policies, but also has a thermal efficiency of over 100%. Low nitrogen gas boiler can greatly reduce the input of fuel costs, and the operation is stable and reliable.
This series of gas fired boilers is a shell-type three-pass wet-back oil-fired gas boiler produced by advanced technology. It consists of the boiler body, connecting flue, deaerator pump, deaerator, burner, soda system, instrument, energy saver, and condenser. And other composition. Compared with old boilers, its most prominent feature is low nitrogen (the nitrogen oxide emissions are greatly reduced during the operation of the boiler, which can reach 30mg/m3 or less, which meets the national policy requirements). In addition, this boiler has the characteristics of compact structure, beautiful appearance, simple operation, safe and reliable operation, and has been widely used in all walks of life.
The low nitrogen gas boiler adopts a fully wet back structure, and the high-temperature flue gas is surrounded by water. The problem of cooling and sealing of the smoke return chamber is solved, and the operating environment of the boiler is improved. The addition of the condenser (made of finned tube) increases the efficiency of the boiler to more than 98% and saves operating costs. At the same time, this series of boiler products are 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 boilers and improve the service life of the boiler.
The WNS gas 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. The front and rear smoke box covers of the boiler are movable, which greatly reduces the difficulty of maintenance and improves the efficiency of maintenance. The heating surface of the WNS series low-nitrogen boiler is well arranged, which guarantees the water circulation and thermal circulation, greatly improves the heat transfer effect, and achieves the best condition.
The design of the rear view device of the low nitrogen gas boiler is convenient for workers to observe the combustion status. The internal smoke pipe of the boiler adopts a threaded structure, which improves the heat transfer efficiency and strengthens the heat transfer effect. Industrial gas boiler combustion, water level, temperature and steam pressure can be automatically adjusted and controlled automatically, which not only facilitates the operation of workers, but also improves safety. Zozen Boilers always insists on producing high-quality boilers and is committed to the research and development of higher-quality boilers. The boilers of our factory can be customized according to the drawings provided by users. Welcome everyone to come to consult!
