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.
This series of circulating fluidized bed is low-temperature combustion. It can desulfurize directly during the combustion process. Besides, the technology and equipment are simple and economic, and the desulfurization efficiency is high. Meanwhile, high temperature cyclone separator in combination with the design of big furnace and low flow rate prolongs the time of coal particles stayed in the furnace, which can ensure complete combustion of coal and effectively improve the thermal efficiency of boilers. In addition, multiple baffle plates are designed on the convection heating surface, which increases the flue gas flow and reduces the dust. Moreover, serpentine tube economizer and air preheater further improve the overall thermal efficiency of the boiler to more than 89%.
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.
The automobile has brought convenience for people's travel. The steam boiler is one piece of the indispensable equipment in the modern automobile production line. As we all know, Geely Auto is one of the top ten enterprises in China's automobile industry. It has achieved rapid development by virtue of its flexible operation mechanism and continuous independent innovation since it entered the field of automobile in 1997. As a first-class manufacturing subsidiary of Geely, Zhejiang Land Rover Automobile Co., ltd decided to expand the Linhai industrial park to produce 300,000 vehicles and key components annually. During the construction of the industrial park, Geely Auto conducted an open bidding and planned to introduce a batch of steam boilers with excellent performance in all aspects.
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.
In the pharmaceutical industry, a large amount of steam generated by boilers is required to sterilize the instruments and equipment at a high temperature, and the heat source provided by the boiler is inseparable in the processes of drying and cooling of the drugs, tableting and granulating. Zhengzhou Lingkong Biomedical Park has established a service support system covering innovative research and development and mass production of pharmaceutical companies. It is an innovation and entrepreneurship base for life science and biotechnology research and development in Henan Province.
Tianjin Normal University is a key construction college of the provincial and ministerial level in Tianjin. It has more than 30,000 faculty members and students. Ensuring such a large group warm in winter is a very important task for the school. Therefore, in the choice of boiler suppliers, Tianjin Normal University conducted a full market research in a rigorous manner.
In food processing enterprises, steam boilers provide a stable heat source for the baking and frying, high-temperature sterilization of food ingredients. Sichuan Aning Food Co., LTD. is a snack food enterprise which mainly manufactures sauce and halogen food.
