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.
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.
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.
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
After having an in-depth understanding about the industrial boiler market, Yushuwan Coal Mine selected ZOZEN as its boiler equipment supplier. ZOZEN provided a scientific and reasonable boiler solution for Yushuwan Coal Mine including multiple sets of gas-fired steam boilers. The boiler solution not only can meet the requirements of production and living, but also can improve the utilization rate of thermal energy. Meanwhile, every ZOZEN gas-fired boiler adopts a low NOx burner to meet the low NOx emission requirement. In addition, the utilization of staged combustion technology greatly reduces the generation of NOx. And, the flue gas NOx content showed in the third-party EIA test is 14-17mg/m3. The value is far lower than the environmental protection standard of 30mg/m3.
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.
With the expansion of business, XinYi Textile introduced the ZOZEN DZL series of biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control. Meanwhile, when the system pressure exceeds the specified value, the full lift spring-loaded safety valve will be automatically opened to release pressure, which can avoid the accidents caused by excessive pressure. In addition,the chain grates of this series of boiler are all manufactured by ZOZEN. A 72-hours test run of the chain grates can ensure the moderate tightness of the grate. Besides, the scientific grate arch design, reasonable air distribution and governor box speed ensure the full combustion of biomass pellet fuel and the overall thermal efficiency of the boi
ZOZEN has been a leading industrial manufacturer after more than 30 years of development. In recent years, with the increasingly strict environmental protection policies, ZOZEN has intensified great efforts in the research and development of gas-fired boiler products and improving the environmental performance and overall thermal efficiency of boilers. As a star product of ZOZEN environment-friendly boiler, the WNS series gas-fired boiler adopts an advanced low NOx burner. In addition, ZOZEN optimizes the design of furnace size, volumetric heat load, and the flue gas flow rate of the convection area to ensure that the NOx emission is less than 30mg / Nm3. In terms of improving the thermal efficiency of the boiler, ZOZEN adopts threaded smoke tubes to enhance the heat transfer effect. Meanwhile, through the application of condensation technology, the sensible and latent heat in the high-temperature flue gas can be fully absorbed, which can increase the inlet temperature and improve the
