In recent years, various relatively building material companies have developed rapidly with the development of the construction industry. Jiangsu Yuhang Board Co., Ltd. was founded in 1972 and has accumulated production and technology experience in the sheet industry for decades. The company's main products include calcium silicate board, fiber cement board, wood grain cement board, fireproof board, explosion-proof board and so on. Among them, non-asbestos calcium silicate board is well-known in the industry for its green and environmental protection characteristics, and has won praise from customers at home and abroad. As a high-tech enterprise in Jiangsu Province, Jiangsu Yuhang Board has become a key enterprise in the production of fiber cement products nationally based on its own technical advantages and stable product quality. Industrial boilers play an indispensable role as one piece of the important heating source equipment in the manufacturing process of sheet products.
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.
After the boiler was put into operation, the WNS series gas-fired hot water boiler would provide a stable heat source for the heating of agricultural greenhouses and living areas in our Science and Technology Park. The characteristic of high efficiency will greatly reduce our costs of heating supply.
We were very satisfied with the ZOZEN gas-fired thermal oil heater which fully met the actual requirements of our production lines. In addition, the automatic control system was easy to operate, which greatly reduced the operation costs and improved the economics benefits for us.
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.
With the increasing environmental problems, environment-friendly gas-fired boilers have attracted more and more attention. In response to the situation, ZOZEN launched the WNS series gas-fired boiler product, which not only had outstanding environmental performance, but also helped many enterprises realize the goal of energy conservation. ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion. Through the commissioning of experienced ZOZEN technicians, the burner can achieve a good combustion state. In addition, the boiler has a large diameter furnace, which can further improve the combustion efficiency.
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
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.
