low nitrogen oxide nox emission boilers in eastern, ZOZEN boiler low nox technical renovation program decreases the nox for blue sky

low nitrogen oxide nox emission boilers in eastern, The price of fuel is constantly fluctuating and with it comes creative ways to be more economical. Finding methods to be more energy efficient is never a waste of time. In the boiler room, efficiency improvements can be found by many sources, however, a common option for energy savings includes the use of an economizer. NOW, ZOZEN will help introduce the economizer. The economizer is a fabricated assembly of finned tubing that captures waste heat extracted from the boiler’s stack flue gases the exhaust that leaves the boiler stack.

ZOZEN announced the partnership with Libbey Inc., the global glassware industry giant, on the low NOx gas-fired boilers. As an industrial boiler manufacturer with more than 30 years of history, ZOZEN shares the same development concepts with Libby. The two sides became friendly and trustworthy partners to improve the atmospheric environment.

The SZS series gas-fired steam boiler produced by ZOZEN Boiler adopts the D-type and full membrane wall structure. The large furnace space ensures the sufficient combustion of the fuel and has good gas tightness. Meanwhile, the furnace body is made of high-quality aluminum silicate fiber and refractory mud for insulation to control the furnace body temperature below 45℃ and control the heat loss; with the additional energy-saving device at the end of the flue gas duct, the boiler thermal efficiency can be improved to more than 98%.

Meanwhile, a set of 36 tph ZOZEN DZL series biomass-fired boiler was in installation in Shandong Province. This boiler system would provide the stable heat source support for the production base of Heze Huihao Textile Co., Ltd. with an annual output of 3,000 tons of knitted fabric and 3,000 tons of rinsed knitted fabric. ZOZEN biomass-fired boiler had a reasonable primary and secondary air ratio and the SNCR intelligent denitrification device at the boiler end, which could ensure that the NOx emission concentration was less than 50mg/Nm3 to meet the environmental protection standards in Shandong Province, helping Huihao Textile realize the ultra-low NOx emission.

ZOZEN WNS series gas fired boiler not only adopts advanced low NOx burners. And through the flue gas recirculation technology, about 10% -30% of the flue gas at the tail of the boiler is sucked into the air inlet of the burner through the flue gas pipe, mixed with the combustion-supporting air, and then entering the furnace, thereby reducing the temperature and oxygen concentration in the combustion area, and finally reducing The amount of thermal NOx is generated, and the NOx in the tail gas of the boiler are less than 30mg/Nm3, which meets the requirements of low nitrogen emissions of the enterprise.enterprise.

At present, the blanking rate of ZOZEN's sheet metal has reached more than 80%, and a large-scale welding and assembly process revolution has been performed. Mechanical automatic welding is used to realize the assembly mold, and gradually reduce the traditional processing methods of scribing assembly and eliminating scribing errors. Meanwhile, the company's use of advanced measurement and testing equipment also provides a strong guarantee for manufacturing high-quality products.

It’s critically important to stay in lock step with your customers to understand how products need to evolve to continue to meet their needs. It’s easy to fall into the behavior of “milking” existing products. Products must continually evolve to remain relevant and useful. The path to success is through continual product innovation. It is the ZOZEN Boiler way, low nitrogen oxide nox emission boilers in eastern.
