Jilin Longyuan Fertilizer Co., Ltd., founded in 2004, is one of the subsidiaries of Longyuan Group. At present, the company has two ammoniation-granulation compound fertilizer production lines with a total annual output of 500,000 tons, a blended fertilizer production line with an annual output of 300,000 tons, and a potash fertilizer production line with an annual output of 100,000 tons. These high-capacity production lines placed high requirements on the steam quantity and quality of the boiler equipment and also posed a huge challenge to the boiler operating costs, especially the fuel costs. According to the actual demands, ZOZEN customized a set of SZL series coal-fired chain grate steam boiler for Longyuan Fertilizer. This series of boiler has sufficient output, high combustion efficiency and wide fuel adaptability, which can fully meet the needs of Longyuan Fertilizer.
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.
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
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
Thermal oil heaters play an important role in the textile industry, providing heat energy for the process of dyeing, drying and printing. Located in Manila (the capital of the Philippines), Pantone Finishing Corporation is a large company engaged in textile products. The rising in natural gas price results in the increases of running cost for original thermal oil heaters. In order to save cost while having no effect on production, the company planned to purchase several energy-saving thermal...

The boiler provided by ZOZEN features high efficiency and fully automatic safe operation, saving the running cost for us. Their devoted customer service brings convenience for us.
As the determination of country to prevent and control air pollution is increasing, various policies have been introduced across the country. Almost every region, the time period and number of boiler renovations have been issued. In order to maximize the cost savings of the company’s operations, most companies will choose to convert coal-fired boilers to gas-fired boilers, and the rubber chemicals industry is no exception. With the increasingly stringent policies and regulations being promulgated in succession, in 2013, Huasheng rubber planning rubber auxiliary energy-saving renovation project, they purchased a 10-ton WNS condensing gas-fired steam boiler at ZOZEN boiler. The condensing boiler is a hull-type three-way pyrotechnic tube structure researched and developed based on the mature technology of the current gas boiler, the heat load of the boiler is low. An additional condenser is installed at the tail of the flue to increase the boiler inlet temperature and reduce the temperatu
Longyang Textile Printing and Dyeing Co., Ltd. is a textile processing company, whether dyeing, drying, sizing and printing are inseparable from the support of steam boilers. Since the textile industry in which Longyang Textile Printing and Dyeing Co., Ltd. is involved consumes a large amount of fuel, the choice of low-cost and environmental-friendly fuel is the first choice for textile manufacturers. The steam quality of steam boiler has a decisive effect on the product quality after dyeing and drying in clothing and textile mills. The consumption of steam boiler fuel in the textile industry is generally relatively large. Therefore, choosing steam boilers can not only effectively improve the quality of textiles in textile companies, increasing production efficiency, and can also reduce labor costs and operating costs of steam boilers. The 15-ton SZL biomass-fired steam boiler produced by two Zozen boilers purchased by Longyang Textile Printing and Dyeing Co., Ltd. not only has high th
