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.
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
With features of low pressure and high temperature, ZOZEN various series of thermal oil heaters have become heat source of many chemical enterprises. ZOZEN YLW series coal-fired(biomass-fired) thermal oil heater is a square coil horizontal chain grate shop-assembled heater of which the chain grate and heater proper are transported separately. Once connected the oil and electricity, the heater can be put in use. This series of heater adopts an advanced structure, including four parts: the radiation furnace heating area, convection tube bundle heating area, waste heat boiler and air heater, which has sufficient heating area and ensures high thermal efficiency of the boiler. Meanwhile, ZOZEN reasonably designed the combustion chamber according to different characteristics of different types of coal and biomass fuel, which not only ensures the complete combustion of the fuel but also improves the combustion efficiency and reduces the formation and emission of flue gas. This series of heate
As a leading manufacturer of the industrial boiler industry, ZOZEN became the boiler supplier of Jinshan Mining with advantages of SZL series biomass-fired boilers in thermal efficiency and environmental protection. This series of boiler adopts double steam drums, and the combustion chamber is surrounded by membrane wall. Meanwhile, the boiler adopts a chain grate. Segmented wind bunkers and wind regulating devices are arranged on the lower part of the boiler to achieve precise air distribution and ensure full combustion of fuel. The thermal efficiency can reach over 88%, and all indicators have reached the international advanced level.
Saturated steam is mainly used for heating, refining and disinfecting processes of the vegetable oil production. The vegetable oil industry requires a large amount of steam. With high sanitary requirements, the vegetable oil processing companies set high requirements for the quality of steam. YongYou is a large cereals & oils company integrating grain storage, trading, transit and processing. According to the characteristics of high steam pressure, high quality requirements and large load fluctuations in the vegetable oil production process, YongYou purchased two sets of 15 tph biomass-fired steam boilers to meet the requirements of production. In addition, the flexible load adjustment can improve the use efficiency of steam.
With increasingly stringent environmental protection policies, coal-to-gas boiler projects are progressing in an orderly manner across the country. In this process, ZOZEN WNS series gas-fired steam boiler with excellent environmental performance has been widely recognized and favored by the market. This series of gas-fired boilers adopts a large-diameter corrugated furnace, which can not only ensure the full combustion of the fuel to a certain extent, but also effectively absorb the thermal expansion. And the threaded smoke tubes have good thermal scalability, scientific airflow design, effectively absorb the flame heat, and combined with the energy-saving devices at the end of the flue, the boiler thermal efficiency can reach over 98%. In addition, in response to the low NOx emission requirements put forward by more and more enterprises, ZOZEN has selected international advanced low NOx burners to easily achieve NOx below 30mg/Nm3, and customized a full set of boiler system design sol
