Industrial boilers have been widely used in the chemical industry all the time. They play an indispensable role in the pretreatment, hydrogenation, decomposition, and distillation of oleochemicals. Hangzhou Oleochemicals Co., Ltd. was founded in 1973 (the predecessor was Hangzhou Grease Chemical Factory) is a state-owned enterprise which was invested and built by the former Ministry of Light Industry of China. The enterprise was restructured in 2000 and it is now a wholly-owned subsidiary of Zhejiang Zanyu Technology Group Co., Ltd. that has formed a style of simultaneous development of multiple products series. It supplies significant raw materials for manufacturing industries in food, chemicals, plastic, rubber, cosmetics, flavor and fragrance fields and deeply win trusts from many customers at home and abroad.
We were very grateful to ZOZEN for giving top priority to the order of our medical materials company during the outbreak of the COVID-19. The prompt delivery not only showed the strength of ZOZEN, but also let us feel the social responsibility and corporate responsibility of a large manufacturing company.
ZOZEN SHL series field assembled hot water boiler is a natural circulation coal-fired water tube boiler with double drums, which is widely used in central heating industry. With advantages in performance, the ZOZEN SHL series coal-fired boiler became an important facility of the boiler room of Xinjiang Huadian Hami Thermoelectric Power Co., Ltd. The horizontal two drums form a shaft-type furnace with the membrane wall and form the boiler proper with the convection tube bundle header, which has the features of fast temperature rising, high thermal efficiency and less occupied area. Meanwhile, this series of boiler adopts the flake type chain grate to improve the operation reliability, which has no coal leakage. In addition, the boiler is equipped with an advanced air distribution system, which can reasonably adjust the air volume according to the coal property and combustion conditions. Moreover, the SHL series coal-fired boiler has advantages of high degree of automation, stable operat
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.
In the face of severe environmental problems and the requirements of the Nanjing Air Pollution Control Regulations, Nanjing Golden Dragon Bus Co., Ltd. decided to purchase a set of high-efficient natural gas steam boiler. After numerous investigations, ZOZEN with strong comprehensive strength and good reputation was noticed. ZOZEN is a large industrial boiler manufacturer. The annual capacity of ZOZEN has reached 25, 000 tons of steam. In addition, the high-quality steam of ZOZEN WNS series gas-fired boiler can effectively ensure the quality of the processes of baking and painting of Golden Dragon Bus. Besides, the large-diameter corrugated furnace of this series of boiler not only enhances the flue gas disturbance, but also improves the heat transfer effect. Moreover, several energy-saving devices are equipped at the tail of the boiler to improve the thermal efficiency of the boiler to more than 98%, which can help Golden Dragon Bus to realized the goal of energy saving and emission
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
In recent years, with the continuous advancement of the Coal-to-Gas policy, Tulufanbei Railway Station decided to introduce two sets of 2.8MW gas-fired hot water boilers, dismantle the existing coal-fired boilers, supporting facilities, draft fans and dust collectors and keep the existing water treatment equipment, circulation pump and feedwater pump in use. After having an in-depth understanding of the requirements of the customer, ZOZEN customized a high-efficient gas-fired boiler solution for Tulufanbei Railway Station. The WNS series hot water boiler recommended in the solution has outstanding advantages. With an automatic control system, the boiler can automatically realize operations such as start-stop, load adjustment, and water supply as the system required. Meanwhile, the large-diameter corrugated furnace of this series of boiler not only increases the heating area but also ensures the full combustion of fuel. In addition, equipped with an advanced low NOx burner, the boiler c
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.
