After having an in-depth understanding about the industrial boiler market, Yushuwan Coal Mine selected ZOZEN as its boiler equipment supplier. ZOZEN provided a scientific and reasonable boiler solution for Yushuwan Coal Mine including multiple sets of gas-fired steam boilers. The boiler solution not only can meet the requirements of production and living, but also can improve the utilization rate of thermal energy. Meanwhile, every ZOZEN gas-fired boiler adopts a low NOx burner to meet the low NOx emission requirement. In addition, the utilization of staged combustion technology greatly reduces the generation of NOx. And, the flue gas NOx content showed in the third-party EIA test is 14-17mg/m3. The value is far lower than the environmental protection standard of 30mg/m3.
With outstanding product quality and environmental protection performance, ZOZEN has occupied a certain market share in the dyeing and finishing industry and has obtained a good reputation. ZOZEN SZL series biomass-fired boiler is an environment-friendly boiler that is jointly developed by ZOZEN and Shanghai Jiaotong University. According to different characteristics of biomass fuels and different burning rates, ZOZEN rationally arranges the heating area of the furnace arch, furnace wall and furnace to ensure the combustion efficiency and design evaporation. Meanwhile, after numerous experiments, ZOZEN rationally arranges the primary and secondary air, which can effectively reduce NOx emissions and ensure the fuel is fully burned.
In the heavy machinery manufacturing industry, the processes of smelting, pouring, and producing finished castings consume a large amount of steam. ZOZEN superheated steam boiler can meet the temperature requirements of these process.
ZOZEN has always been committed to continuously improving the thermal efficiency of gas-fired boilers. WNS three-pass condensing gas-fired steam boiler is an environmentally friendly boiler product of ZOZEN. With advanced low NOx burner, the boiler thermal efficiency can be as high as 98% while achieving ultra-low emission of NOx≤30mg/Nm³. After the fuel is fully combusted in the large-diameter corrugated furnace, the high-temperature flue gas flows backwards to the second pass along the furnace through the reversal chamber , that is, the threaded smoke tube bundle area; After convective heat transfer, the boiler flue gas temperature gradually decreases and goes to front smoke box and turns to 3rd pass, that is, the smooth tube bundle area; Finally, the flue gas enters the economizer and condenser through the rear smoke box, and flows into the chimney and is exhausted into the atmosphere.
In the process of garment printing and dyeing, heat setting, dyeing, drying and other processes require a stable steam heat source provided by the boiler. Chongqing No.3533 Printing and Dyeing and Clothing Co., Ltd. is a large-scale printing and dyeing base in southwestern China. Its products sell well all over the world and meet the needs of foreign military needs such as Britain, Italy, the United States, Spain, etc.
Founded in 1991, Sichuan Liji Pickles & Flavouring Co., Ltd. is a large-scale agricultural and sideline products processing enterprise mainly engaged in the production of pickles, seasonings and red oil series dishes. In order to greatly improve production efficiency and effectively guarantee the stability of product quality, Liji Pickles & Flavouring introduced a series of automated production lines. The boiler is one of the important equipment in its automated production line. The sterilization and disinfection processes during the processing require the steam provided by the boiler.
In food processing enterprises, steam boilers provide a stable heat source for the baking and frying, high-temperature sterilization of food ingredients. Sichuan Aning Food Co., LTD. is a snack food enterprise which mainly manufactures sauce and halogen food.
In the corrugated paper processing line of the packaging industry, the steam boiler is an important heating system for increasing the temperature of the paperboard and is one of the essential equipment. Founded in 1995, Fijian Nanan Lianfa Paper Industry Co., LTD. attached great importance to technical input and strictly controlled product quality. At the same time, they knowed thoroughly that the efficiency of boiler operation would directly affect the company's product quality and economic benefits.With the fierce market competition, Lianfa Paper decided to eliminate backward production capacity and introduce high-quality and high-performance environmentally friendly gas-fired steam boilers.
