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.
Hohhot Huaou Starch Co., Ltd, established in 1992, is a large-scale potato furthering processing enterprise in China, whose potato starch possesses excellent whiteness, viscosity, clarity, gelatinization temperature and is widely applied. In the processing of potato starch, steps like dehydration and drying decide the quality of potato starch. Therefore, steam boiler with high output and efficiency plays an essential role in the enterprise's production. After a series of market investigation, Hohhot Huaou Starch Co., Ltd decided to purchase two sets of ZOZEN WNS series gas-fired steam boiler as the heat supply for its production line.
Based on the abundant experience accumulated from the cooperation with numerous pharmaceutical enterprises, ZOZEN Boiler customized two sets of WNS series gas-fired steam boiler featured with safe operation, energy saving and few environmental pollution that could meet the actual demands of production lines, which won the satisfaction and trust of Haida Shehuage Pharmaceutical.
In order to meet the strict environmental protection requirements of Beijing city, ZOZEN designed WNS series gas-fired hot water boilers that used clean energy natural gas as fuel and adopted the advanced low NOx burner to ensure that NOx emission was lower than 50% and the flue gas was exhausted into the atmosphere via 15-meter chimney.
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
We conducted a rigorous market research on the industrial boiler market before purchasing the boiler. Finally, we selected ZOZEN which had good boiler quality and professional services. At present, ZOZEN WNS series gas-fired steam boiler had become an important part of our production line. The feature of automatic operation greatly saved labor costs for our company.
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.
