condensing coal fired boiler, ZOZEN condensing gas-fired horizontal steam boiler is a preferred choice for coal-to-gas conversion in the paper industry

Recently, data from the National Bureau of Statistics showed that China’s industrial boiler output from January to July in 2020 was 184,780.8 tph, a decrease of 24.8% year-on-year, showing a downward trend. Against the background of a sharp decline in the domestic industrial boiler industry, ZOZEN Boiler managed to overcome the difficulties and achieved a slight increase in output.
condensing coal fired boiler, ZOZEN SZL series coal-fired steam boiler is package or shop-assembled water tube boiler with double-drum and chain grate structure.Boiler with capacity of 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment.
With over 30 years of experience in boiler manufacturing, Wuxi ZOZEN Boilers Co., Ltd. has more than 400 kinds of gas-fired boilers, biomass-fired boilers, coal-fired boilers and thermal oil heaters which are widely applied in chemical, food, brewing, heating, paper, printing and dyeing, rubber and other industries. In particular, ZOZEN’s gas-fired boilers can reduce the flue gas temperature to less than 60℃ to improve thermal efficiency and save boiler operating costs for users.
ZOZEN thermal oil heater is equipped with a variety of waste heat recovery devices. The heat loss is reduced through the recovery and utilization of high temperature flue gas waste heat, and the overall thermal efficiency of the thermal oil heater is increased to more than 95%, which is better than the overall industry level, condensing coal fired boiler.
The complete set of WNS series gas-fired hot water boiler system customized by ZOZEN Boiler for Jilin Mingde Education adopts the corrugated furnace which not only increases the strength and flexibility of the furnace, but also enhances the flue gas disturbance to effectively improve the heat transfer effect. The threaded smoke tube with advanced manufacturing technology has been continuously optimized to effectively absorb the flame energy, and its heat transfer coefficient is 1.2 times higher than that of ordinary smoke tube. At the same time, with the additional finned tube condenser at the end of the flue gas duct, the exhaust gas temperature can be lowered and the boiler thermal efficiency can be as high as over 95%. According to the energy efficiency test conducted by the Thermal Energy Testing Center of the Special Inspection Institute, the performance indicators of the WNS series gas-fired boiler are higher than design requirements and have reached the advanced level at home and abroad.
condensing coal fired boiler, The research and formulation of enterprise development strategy is a dynamic process with continuous improvement and innovation. The professional title evaluation of front-line staff means that ZOZEN’s salary system is further completed and optimized to provide a basis for the confirmation and change of staff’s salary, which reflects the company’s emphasis on talents cultivation to the greatest extent. We will strive to build ZOZEN into an excellent team with internal harmony and vitality as well as external unity and competitiveness.
