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.
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.
A safe and high-efficient thermal oil heater is very important to an enterprise, which directly affects the product quality and the economic benefits. In November 2017, the burst of the pipeline of the existing thermal oil heater triggered a fire at Jiangxi Huachen Spice Chemical Co., Ltd. The fire caused considerable losses to the enterprise. Immediately, the leadership of the enterprise decided to repurchase a set of high-quality thermal oil boiler. With good market reputation and strong company strength, ZOZEN got the trust of Huachen Spice. ZOZEN YQW series gas-fired thermal-oil heater has excellent safety performance. The functions of over-temperature alarm, low oil level alarm and over-pressure alarm can ensure the stable operation of the heater. In addition, because the inner coil of the radiant section of the heater absorbs much more heat than the middle and outer rings, ZOZEN designed a large flow rate inner coil to ensure the safe and reliable operation at high temperature.
Because of the characteristics of high temperature and low pressure, the thermal oil heater becomes an important piece of equipment of the fine chemical industry. Wuhai Shilian Environmental Protection Technology Co., Ltd. was established in April 2018. With a total investment of 320 million yuan, the company was a reorganization of Wuhai Black Cat Sanxing Fine Chemical Co., Ltd. After sufficient market research and technical demonstration, Wuhai Shilian decided to re-plan the product structure of the original company and invest a 20,000-ton-per-year phenol series technology transformation project including 10,000 tons annual output of resorcinol, which is mainly used for rubber adhesives.
ZOZEN has been implementing the Belt and Road initiative all the time. Qingdao United Zhenye Energy Saving Technology Co., Ltd carried out an in-depth cooperation with Kazakhstan on environmental protection technology of oil fields. ZOZEN provided stable and efficient thermal energy for the project. The first batch of YQW series thermal oil heaters and WNS gas-fired steam boilers has been delivered to Kazakhstan. It indicated that ZOZEN has got the affirmation of users in Kazakhstan again.
