Facing strict environmental protection standards – NOx emission ≤30mg/m³. The ZOZEN’S R&D team continues to explore and practice, creatively combining ultra-low nitrogen combustion technology with WNS boiler manufacturing technology. Key breakthroughs have been achieved in the two core technologies of staged combustion and FRG flue gas recirculation. As a result, today’s horizontal internal combustion low-nitrogen boilers were born, and the NOX emission can reach 26mg/m³. The LPG fired steam boiler is factory-assembled to ensure that the boiler can be quickly installed on the user’s site.
Except for water supply, gas supply and electrical connection accessories, WNS series steam boilers do not need any other building structures and special installation procedures. A series of testing and debugging work have been carried out before the boiler leaves the factory to ensure the quality of the boiler. This type of boiler product is mainly composed of boiler body, connecting flue, burner, soda system, instrument, economizer, condenser, etc. The combustion is clean, the emission is pollution-free, the operation is convenient, and the output is sufficient.
LPG boilers are widely used in hospitals, schools, textile factories, garment factories, large supermarkets, garment factories, printing and dyeing factories, hotels, canteens, restaurants, food factories, beverage factories, soy products factories, meat products factories, canning factories , wineries, pharmaceutical factories, packaging factories, building materials factories, paint factories, swimming pools and other enterprises and institutions. The LPG fired steam boiler has high combustion efficiency, saves fuel, and has low investment cost for purchasing fuel. The boiler adopts full-edge butt weld, which is safe to use, has a long service life and low maintenance costs.
The tail of the WNS series boiler is equipped with a flue gas condensation recovery device, which can effectively control the exhaust gas temperature and has high thermal efficiency of the boiler. The automatic burner is adopted, and the water supply adopts continuous electric adjustment, and the combustion efficiency is high. The boiler adopts a quick-installation structure, and the whole boiler is designed on a strong steel base, which is convenient for installation and transportation, saving the space occupied by the boiler room.
The boilers of the WNS series completely release the gas burning torch inside the boiler furnace. The heat is transferred from the inside of the furnace, and the method of reducing the temperature loss provides heat energy. We can customize the WNS series gas steam boiler system according to the drawings. The thermal efficiency of this series of steam boilers is as high as 98%, and the output is sufficient, which can realize automatic operation. The LPG fired steam boiler is an ideal green product with high efficiency, low consumption and low pollution.
