In the printing and dyeing industry, industrial boilers have always provided the important heat source support for the printing and dyeing, drying, slashing and other production processes. Jiangsu Zhongcheng Printing and Dyeing Co., Ltd., established in 2001, is mainly engaged in the printing and dyeing of various kinds of cotton and polyester fabrics. Its main products are cotton and linen fabrics, elastic fabrics, high count and high density fabrics. Facing the increasingly strict environmental protection standards, in order to reduce energy consumption and save costs, Zhongcheng Printing and Dyeing decided to upgrade the boiler system and introduce ZOZEN SZS series gas-fired steam boiler to pursue better economic and environmental benefits.
Heilongjiang Changfeng Coking Co., Ltd., founded in 2014, mainly produces coke, tar, crude benzene and other chemical products. In the second half year of 2019, the company invested more than 60 million RMB to launch a 6 MW coal gas thermal power project which required a set of 45 tph gas-fired boiler and the 6 MW condensing steam turbine generator set. If the project is put into use, it is expected to generate 60 million kWh of electricity per year and form a heat supply network covering 300,000 square meters, which is a municipal-level key industrial project and is highly valued by the local government. However, this set of steam boiler with a rated pressure of 3.82 Mpa and a steam temperature of 450℃ is a kind of A-grade mid-temperature and mid-pressure boiler, which sets high requirements for boiler design and manufacture.
Laiyang Fusheng Food Co., Ltd. is an enterprise engaged in the processing of agricultural and sideline products, whose business covers the preservation, refrigeration and sales of raw meat, raw meat products, aquatic products, fruits and vegetables. In September of 2019, Fusheng Food decided to launch a frozen food production and processing project which needed to pass the strict environmental assessment implemented by the local government. It included the environmental impact of the company's heating equipment which was used to generate hot water for the blanching process of semi-finished raw materials. Due to the strict air pollutant emission standards of Liyang city, Fusheng Food ordered a set of ZOZEN WNS series three-pass gas-fired steam boiler after a series of market investigation.
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.
Hubei Grand Life Science and Technology Co., Ltd., founded in 1995 and formerly known as Huanggang Fuchi Pharmaceutical Co., Ltd., is a wholly-owned subsidiary of Grandpharma (China) Co., Ltd.. Hubei Grand adopts the taurine production process using ethylene oxide as the initial raw material, which requires a sufficient and stable heat source supply provided by the boiler equipment with high requirements. In order to better meet the heat source demand of the taurine production line, Hubei Grand finally chose ZOZEN's YLW series coal-fired horizontal thermal oil heater.
In recent years, the state has paid increasing attention to environmental protection and launched the "coal to gas" policy. To actively respond to the policy and reduce the pollution of heating supply, Xincheng Heating Station upgraded the boiler equipment timely by introducing 2 sets of ZOZEN's SZS series gas-fired hot water boiler. This kind of boiler is featured with safety, high efficiency, energy saving and environmental protection, which provides solid guarantee for the central heating of residents.
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
ZOZEN has accumulated a good market reputation in the Fujian industrial boiler market, providing reliable and stable steam heat source guarantee for many textile printing and dyeing enterprises. Among them, ZOZEN WNS series gas-fired steam boiler has the characteristics of durability, high efficiency and low consumption, which greatly reduce the production cost of textile enterprises and effectively improves economic benefits. During the manufacturing stage, ZOZEN advanced automatic production lines ensure the quality of the welding and assembly of the boiler, reduces the assembly stress and prolongs the service life of the boiler. During the installation and commissioning phase, the large-diameter corrugated furnace of the WNS series gas-fired boiler, the threaded flue pipe for enhanced heat transfer, and the condenser added at the end of the flue effectively improve the heat transfer effect and ensure that the overall thermal efficiency of the boiler is over 98%.
