　　Application industry: Steam boiler: widely used in various industrial industries, such as textile, chemical, papermaking, machinery, food, agricultural product processing industry, etc

　　Hot water boiler: widely used for heating, bathing, and domestic hot water in hotels, schools, guesthouses, residential areas, and other enterprises and institutions

　　 Product IntroductionThe WNS series low nitrogen condensing boiler is a fully automatic, horizontal internal combustion, low nitrogen condensing quick loading fuel (gas) boiler. The boiler body adopts a wet back type two return structure: the corrugated furnace and the combustion chamber are the return, and the threaded smoke pipe forms the second return. The energy-saving device and condenser are placed at the top of the boiler, forming the third return path of flue gas outside the furnace.

　　 Performance CharacteristicsEfficient and energy-saving. The energy-saving device and condenser have a large heat exchange area, and the condensation rate of water vapor in the flue gas is high. They can fully absorb the heat released by the condensation of water vapor in the flue gas, and the thermal efficiency can reach over 99%. The use of threaded smoke pipes for convective heating surfaces effectively improves the heat transfer efficiency of the boiler. Good environmental protection effect. Some harmful components such as CO2, NOX, SO2 in the flue gas dissolve in the condensate, effectively reducing the emission of atmospheric pollutants. By adopting a large-sized furnace structure and flue gas recirculation technology, it is possible to achieve ultra-low nitrogen emissions for gas boilers, with NOX emissions ≤ 30mg/Nm3, fully meeting the increasingly stringent national environmental protection requirements. The energy-saving device, condenser, and boiler are arranged as one unit, with quick installation and easy installation, compact structure, and beautiful appearance. Less land area, reducing infrastructure investment. The spiral finned tubes and shells of the energy-saving device and condenser are made of ND steel material that is resistant to sulfuric acid corrosion, greatly improving the service life of the equipment. The combination of intelligent combustion control and fully automatic safety interlock protection system ensures economical, environmentally friendly, and safe operation.

　　working principleIn the exhaust heat loss of a boiler, in addition to the sensible heat of the flue gas, water vapor also carries away a large amount of latent heat of vaporization. If the exhaust temperature is lowered to condense all or part of the water vapor in the flue gas, and the latent heat released during the condensation process is recovered and utilized, the effective utilization heat of the boiler will increase, which will significantly improve the thermal efficiency of the boiler. WNS type low nitrogen condensing gas boiler focuses on key technical factors such as the relationship between the condensation rate of water vapor in flue gas and exhaust temperature, the relationship between condensation rate and thermal efficiency, and the corrosion rate of condensed water on different steel grades. By designing the heating surface reasonably and reducing the exhaust temperature, the condensation rate of water vapor in flue gas meets the design requirements, greatly improving the thermal efficiency of the boiler. Due to the use of large-sized furnace structure and flue gas recirculation technology, ultra-low nitrogen emissions can be achieved for gas boilers, with NOX emissions ≤ 30mg/Nm3.
