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 outstanding product quality and environmental protection performance, ZOZEN has occupied a certain market share in the dyeing and finishing industry and has obtained a good reputation. ZOZEN SZL series biomass-fired boiler is an environment-friendly boiler that is jointly developed by ZOZEN and Shanghai Jiaotong University. According to different characteristics of biomass fuels and different burning rates, ZOZEN rationally arranges the heating area of the furnace arch, furnace wall and furnace to ensure the combustion efficiency and design evaporation. Meanwhile, after numerous experiments, ZOZEN rationally arranges the primary and secondary air, which can effectively reduce NOx emissions and ensure the fuel is fully burned.
As a well-known industrial boiler manufacturer, ZOZEN focuses on the research and development of energy-saving technology. In order to help Hongda Textile to reduce energy consumption, ZOZEN customized the WNS series gas-fired boiler system according to the actual requirements of its production lines. Through the application of several patent technologies, this series of boiler has truly realized energy saving and high efficiency in terms of combustion efficiency, exhaust gas temperature, etc. Equipped with an advanced burner, the WNS series boiler realizes reasonable air distribution. Meanwhile, the large-diameter corrugated furnace of ZOZEN WNS series gas-fired steam boiler not only increases the heating-transfer surface but also ensures the full combustion of fuel, which increases the efficiency and reduces the consumption of fuel. In addition, ZOZEN adopts the patented condensing technology, which can fully absorb the waste heat of the exhaust gas, improve the water inlet temperatu
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.
Confronted with the increasingly severe environmental protection policies, ZOZEN has made progress in the research and development of technologies in recent years. WNS series gas-fired boilers with features of high efficiency and low emissions are preferred by the industrial boiler market. This series of boiler adds a radiant heating surface to increase the heat transfer coefficient. Besides, the boiler adopts high-efficient threaded flue tubes to slow down the flue gas flow rate and fully absorb heat. In addition, energy-saving devices are equipped at the tail of the flue to increase the thermal efficiency to above 98%. The efficiency is superior to level 1 national energy efficiency standard. Moreover, the advanced low NOx burner greatly reduces the emission of NOx to 30 mg/m３. The ultra low emission provides guarantees for clean production and sustainable development of enterprises.
In response to national environmental protection policies and initiatives for energy conservation and emission reduction, many printing and dyeing companies have technically reformed coal-fired boilers on their original production line. Among them, Wujiang Lianhua Dyeing and Finishing Co., Ltd. was established in 2002, and has now developed into a large-scale production enterprise integrating weaving, dyeing and finishing, printing and import and export trade.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
