Shijiazhuang Huayuan Mineral Wool Board Co., Ltd. was founded in 2003. Its decorative sound-absorbing mineral wool board is popular and is widely applied in the interior decoration of various buildings such as cinemas, auditoriums, conference halls, etc. There are increasingly higher demands for the sound absorption effects of buildings, which also puts forward higher requirements for the production technology of decorative sound-absorbing mineral wool board. The production of sound-absorbing mineral wool board mainly adopts the wet processing whose dewatering and drying processes require the stable heat source provided by industrial boilers. In order to further improve the product quality, Huayuan Mineral Wool Board decided to introduce a set of ZOZEN YQW series gas/oil-fired thermal oil heater.
In order to realize green production and environmental protection effects, Longwang Food decided to purchase the natural gas steam boiler and sets strict requirements for the eco-friendly performance of boiler. After knowing the huge steam demands of Longwang Food's diary and soybean products production lines, ZOZEN Boiler recommended the SZS series gas-fired saturated steam boiler which has sufficiency output, high thermal efficiency and outstanding eco-friendly performance.
Wuxi Pacific Fertilizer Co., Ltd., established in 1994, is a large-scale compound fertilizer manufacturer in East China. The company produces economical and high-quality compound fertilizers with great market demands and sales volume. Considering that compound fertilizers with high concentration and long effect have better market prospect, Pacific Fertilizer decided to enlarge the fertilizer production line via renewing the boiler equipment. After the field visits for a comprehensive understanding, Pacific Fertilizer finally signed the contract with ZOZEN Boiler to purchase a set of WNS series gas-fired steam boiler with sufficient output and high thermal efficiency as the heating equipment on the fertilizer production line.
To meet Ningde Amperex Technology’s demands of production line reconstruction, ZOZEN Boiler designed the YQW series gas-fired thermal oil heater that could realize low-pressure and high-temperature heat supply and precisely control the temperature of heat medium oil to further guarantee the steady heat supply for the battery production line.
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 order to meet its heating requirements in winter, Ainengju Photovoltaic introduced the ZOZEN DZL series biomass-fired boiler. Being aware of the importance of innovation and development, ZOZEN pays attention to the cultivation of talents and the construction of talent pools all the time. ZOZEN also actively reaches cooperation with universities and research institutes. ZOZEN DZL series biomass-fired boiler is longitudinal arrangement with a single drum. According to the characteristics and fuel rate of different biomass fuel, ZOZEN reasonably arranges the heating surface of the furnace arch, furnace wall and furnace chamber of the DZL series of boiler to ensure the overall thermal efficiency and the normal and stable operation of the boiler.
This time, Shanghai High-New Science & Technology Development Co., Ltd. selected the ZOZEN YQW series gas-fired thermal oil heater and supporting waste heat boiler for its project in Ethiopia. To ensure the hot-pressing quality of the wood-based panels, the temperature of the hot-pressing board surface should be as uniform as possible. Therefore, High-New Science & Technology set clear requirements that the oil temperature and operation of the thermal oil heater should be stable. This series of boiler adopts a waste heat boiler to recover high-temperature flue gas. The team generated through the heat exchanges of the waste heat boiler can heat the mill, rubber making machine and other facilities that require steam heat source. The waste heat boiler not only further improves the fuel utilization, but also improves the overall thermal efficiency of the heater to more than 95% and reduces the operation costs. In addition, many advanced facilities independently developed by ZOZEN provide a
Jiangsu Hengtong Printing and Dyeing Group Co., Ltd. set high requirement for the automatic operation and safety of the thermal oil heater which had great importance to its production line. After rigorous market research, Hengtong purchased a set of ZOZEN YQW series gas-fired thermal oil boiler in 2018. Equipped with an advanced burner, this series of boiler can realize fully automatic operation, including automatic combustion, automatic adjustment of the liquid level of the expansion tank, outlet temperature, flow rate and automatic protection. Meanwhile, the PlC control system is easy to operate. Various kinds of settings can be completed through the intelligent man-machine interface. In addition, the boiler has been in stable and high-efficient running since its operation, which was highly praised by Hengtong. This time, with the expansion of the production scale, Hengtong planned to get another thermal oil heater and cooperate with ZOZEN again.
