WNS type gas-fired boiler adopts horizontal three-return wet-back structure and natural circulation. We are looking for Zozen Boilers brand, quality assurance, all kinds of qualification certificates are complete. Gas steam boilers adopts advanced manufacturing technology, strict quality inspection, safe use is guaranteed. This series of boilers are made of high quality material, fine workmanship and long service life.
This series of boilers make the combustion process as close as possible to the theoretical air volume conditions during operation. With the reduction of excess hydrogen in the flue gas, the generation of ANOX can be discharged. This is one of the most simple ways to reduce the 0D release. Generally, it can reduce the N0X emission by 15-20% The most reasonable excess air coefficient should be selected during design and operation.
The effect of reducing NOx emission by flue gas recirculation of gas-fired boiler is related to the fuel type 4 gas recirculation. The experience shows that when the flue gas recirculation rate is 15-20, the OX emission concentration of gas E can be reduced. The reduction of NOx with the flue gas again unfortunately E plus T plus, and is related to the burning type M temperature, the higher the burning temperature, the greater the shadow of the flue gas re rate AN0x reduction rate. The gas steam boilers is fully installed out of the factory to ensure that the boiler can be installed quickly on the site of the user. Except for water, gas and electrical connection accessories, no other construction and special installation procedures are required. Before the boiler leaves the factory, a series of testing and commissioning work have been carried out to ensure the quality of the boiler leaves the factory.
Zozen Boilers R&D team continues to explore and practice, combining ultra-low nitrogen combustion technology with WNS boiler manufacturing technology, to achieve a key breakthrough in two core technologies of staged combustion and FGR flue gas recycling. Thus developed a classic horizontal internal combustion type low nitrogen boiler, NOx emission can reach 26mg/m3, meet and higher than the environmental protection requirements. The series of steam boilers are widely used in chemical industry, food industry, building materials industry, paper mill, packaging factory, clothing textile factory, printing and dyeing factory, hospitals, schools, hotels, offices, greenhouse, cannery, winery, coating plant, swimming pool, washing plant, etc.
The boiler design is reasonable, has the natural circulation boiler characteristic, has the exact visible water level, any one holds the operation certificate the fireman can be competent operation. Adopt international new technology, large volume design of combustion chamber. Equip the world famous brand burner, make the combustion more fully, the efficiency is higher, the failure rate is lower. Adoption of advanced corrugated furnace structure, not only increase the heat transfer area, but also meet the free expansion of the furnace after heating. WNS series steam boiler set over temperature, overpressure, water shortage, leak detection, flameout and other protection functions, boiler operation is safe and reliable.
The gas steam boilers has the advantages of light weight, less occupation, less capital construction cost and high degree of automation. The boiler is factory, easy to install, only need to be in place, connect the pipeline, power supply, can be put into operation. This series of gas-fired boilers adopt efficient burners, complete combustion, no air pollution, low noise. Boiler automatic operation, combustion, water level, temperature and steam pressure are automatic regulation, automatic protection. Cigarette door adopts hinge structure, window type open, easy to repair, check, clean up. Welcome customers to our factory to consult and purchase boiler, we can according to the needs of users, customized boiler services, welcome to visit!
