Wuxi Guotai Color Printing Co., Ltd., established in 1958, mainly engages in the production and sales of printing and flexible plastic packaging products. At present, the company is committed to developing and producing the flexible plastic packaging products in the agrochemical field with several compound production lines for printing, which can meet the demands for protective packaging in the agrochemical, daily use chemical, food, medicine and other fields. In order to further improve the production capacity and achieve higher economic benefits, Wuxi Guotai Color Printing Co., Ltd. ordered a set of WNS series gas-fired and oil-fired three-pass condensing steam boiler from ZOZEN Boiler. This type of boiler has the characteristics of sufficient output, high thermal efficiency and small occupied area to help the enterprise save a lot of fuel costs and basic construction costs.
Worldon (Vietnam) Co., Ltd. is an overseas project of Shenzhou International Group and is a clothing company with the concept of green production. The company, fully established and put into production in 2016, mainly produces the knitted garments of international brands such as Nike, Uniqlo, Adidas and so on. In order to meet the increasing production demands and cut the production costs at the same time, Worldon (Vietnam) Co., Ltd. successively purchased 3 sets of high-efficiency and energy-saving SZL series chain grate coal-fired steam boiler from ZOZEN, which effectively improved Worldon's production capacity and product quality, and also realized the goal of energy saving and emission reduction to help Worldon fulfill the green production.
There were abundant oil resources in Venezuela, so Inversiones Goa 7 C.A intended to use light diesel oil as the fuel of boiler to reduce the operating costs of enterprise. Light diesel oil was featured with low viscosity, good fluidity and few content of heavy metal and sulfur, whose combustion has low pollution to the environment. What's more, light diesel oil had no need to be heated in the process of transportation and atomization, so direct ignition could be used to start the boiler. In this case, ZOZEN Boiler customized the WNS series light diesel oil fired boiler system solution for Inversiones Goa 7 C.A with advantages of sufficient capacity, easy installation and maintenance, convenient operation and so on.
Considering the expansion of company business and actual demands of production line, Zhengzhou Yisheng decided to introduce the highly-efficient and eco-friendly WNS series gas-fired steam boiler produced by ZOZEN to both improve product quality and cut production cost. Starting from the source of production line, the company intended to get higher economic benefits and achieve the goal of environmental protection.
The new process using the ethylene oxide method has low production costs and stable product quality, however, the yield of the ammonification process and the production continuity are the key points in the process. Therefore, Jiangyin Huachang Food Additive Co., Ltd. has set clearly high requirements for the entire boiler system. ZOZEN Boiler tailor-made the design of the YQW+WNS series boiler system project in order to meet the sufficient and continuous heating source support of the food additive production line. Among them, the body of YQW series gas-fired thermal oil heater adopts three-pass round coiled tube structure, with sufficient heating surface, and the energy-saving device installed at the end of the furnace can ensure the thermal efficiency up to 95%. The advanced combustion device can realize low NOx emissions of the entire boiler system, meanwhile ZOZEN Boiler has equipped the automatic control system to ensure the continuous and efficient operation of the heating source
After the boiler was put into operation, the WNS series gas-fired hot water boiler would provide a stable heat source for the heating of agricultural greenhouses and living areas in our Science and Technology Park. The characteristic of high efficiency will greatly reduce our costs of heating supply.
We were very satisfied with the ZOZEN gas-fired thermal oil heater which fully met the actual requirements of our production lines. In addition, the automatic control system was easy to operate, which greatly reduced the operation costs and improved the economics benefits for us.
In order to improve the production process, Jiangxi Hetian New Energy Technology Co., Ltd. selected ZOZEN as its heat source equipment supplier. With outstanding energy-saving performance, the WNS series gas-fired boiler provided stable steam heat source support for the production of batteries. This series of boiler adopts the wetback structure. The large-diameter corrugated furnace not only effectively absorbs thermal expansion, but also has sufficient steam storage space and heating area. At the same time, ZOZEN customized the boiler according to the requirement of the user. The boiler adopted a two-pass design. The economizer and condenser were equipped at the end of the flue, which could make full use of the waste heat to increase the boiler inlet temperature, improve the boiler thermal efficiency to more than 98% and save costs for users. It is worth mentioning that ZOZEN not only has advanced production technologies, but also has professional and perfect services.
