As a leading enterprise in the industrial boiler industry, ZOZEN Boiler insists on innovation to design a series of steam biomass fired boiler that are energy-saving and eco-friendly and that can achieve the ultra-clean emission. They become the new choices for major enterprises to save energy and reduce emission.
In recent years, with the advancement of air pollution control, low-efficiency but high-pollution coal-fired boilers have been gradually replaced by the gas-fired boilers and other eco-friendly boiler products. However, due to the limits of natural gas supply and gas pipelines, the promotion and use of gas-fired boilers in China still have certain difficulties. Therefore, steam biomass fired boiler has gradually been recognized and promoted by many domestic environmental protection departments as the alternatives of gas-fired boilers by virtue of characteristics such as eco-friendly and low operating costs.
ZOZEN Boiler has been designing and manufacturing the chain grate boilers since its establishment with mature technologies and fruitful results, and has obtained a number of national patents. At present, ZOZEN biomass-fired chain grate boilers cover DZL, SZL, DHL and SHL four series of industrial boilers and ZZ series of power generation boiler, which can adapt to a variety of fuels such as biomass particles, wood pellets, palm shells, straws and so on. With the excellent quality and performance, ZOZEN biomass-fired boilers have been widely applied all around the world and also have accumulated a good market reputation.
Due to the wide range of fuel sources, biomass-fired boilers usually have problems such as insufficient combustion, scaling and coking. To effectively solve the problems, ZOZEN Boiler, cooperating with Shanghai Jiaotong University, conducts the combustion tests on various biomass-fired boilers at home and abroad and establishes mathematical models. Based on the experimental results, ZOZEN scientifically arranges the furnace arch, furnace wall, furnace heating surface and secondary air. ZOZEN can also customize the boiler type according the specific requirements of customers for fuels, which is favored by customers. Recently, ZOZEN has successively reached the cooperation with Jinshan Mining and Yigao Biotech, Hunan Leading Construction Technology and projects have been completed one after another.
In September, ZOZEN SZL series biomass-fired boiler provided for Jinshan Mining was commissioned well and put into use. The boiler had a higher furnace and reasonable grate speed to ensure the sufficient combustion and a high thermal efficiency of over 88%. Meanwhile, the ash falling device independently developed by ZOZEN was added in the boiler convention area, which had good tightness and could greatly reduce the workload of biomass-fired boiler operation and maintenance personnel to help Jinshan Mining realize the clean production.
At the same time, 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.
