In response to national environmental protection policies and initiatives for energy conservation and emission reduction, many printing and dyeing companies have technically reformed coal-fired boilers on their original production line. Among them, Wujiang Lianhua Dyeing and Finishing Co., Ltd. was established in 2002, and has now developed into a large-scale production enterprise integrating weaving, dyeing and finishing, printing and import and export trade.
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.
Sichuan Energy Investment has always formed a profound cooperation with ZOZEN. As an important window for opening up to the northeast of China and participating in the international specialization, Suifenhe has developed into a large-scale Russian wood import and distribution center. With the rapid development of the wood import and export processing industry, the ZOZEN SZL series biomass steam boiler project was installed here, providing concentrated steam for wood drying of wood processing enterprises in the Sino-Russian trade zone.
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.
The production of paper products requires the processing of steam heat sources. Therefore, the performance of steam boilers will directly affect the output and quality of paper products. Sichuan Shubang Industry Co., LTD. is a professional manufacturer of household paper, high-strength corrugated paper and tuck board. The company has nine advanced production lines and is one of the top ten enterprises of the papermaking industry in Sichuan Province.
As the important heat source equipment for the production line of insulating materials, the thermal oil heater plays an important role in the production process. Sichuan EM Technology Co., Ltd. is a technology-based listed company specializing in R&D and manufacturing of new materials. Based on new insulation materials, it focuses on the development of optical film materials, environmentally friendly flame retardant materials and other products.
In the production processes of various seasoning vegetables including pickled vegetables, steam supplied by the boiler is required for processes such as high temperature sterilization and heating. Sichuan Jixiangju Food Co., Ltd. is a Sino-Korea joint venture committed in research, production and sales of high-grade seasoning vegetables and pickled vegetables. The products are sold all over the country and exported to many countries and regions overseas.
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.
