The waste heat power generation system is essentially similar to the thermal power generation system. Its main work principle is:
All kinds of fumes are produced in the production process of traditional building materials industry. This part of the flue gas has a lot of heat energy. In the past, it was usually discharged directly from the upper part of the chimney without any valuable utilization. The waste heat power generation system uses waste heat boiler to recover the heat energy in this part of the high temperature flue gas, to heat the water to superheated steam, and superheated steam to drive the turbine generator unit to run, thus generating electric energy to the high voltage power supply network of the factory, greatly reducing the amount of power purchased from factories and generating huge economic benefits.
Since 2001, our institute has carried out a lot of theoretical research on the utilization technology of waste heat resources of low temperature waste gas. It is considered that the low temperature waste heat recovery technology and the domestic low-temperature waste heat recovery equipment can fully utilize low-temperature waste heat resources such as cement, glass and other building materials industries, and are applied to power generation. Since then, with the practical application and construction of the project, the technology has been gradually improved and applied and promoted. The technology was successfully applied to cement production line in 2006, and was successfully applied to glass production line in 2007.
The low-temperature waste heat power generation project designed by our Institute of Jiangsu walrun Group Co., Ltd. is the first national glass factory to apply low-temperature waste heat power generation technology to actual projects. The project is also awarded the two prize of science and technology progress award of building materials science and Technology Award in 2009. In the same year, the People's Republic of China science and technology novelty report was issued by the Ministry of technology.
In 2009, the thermal power generation project of Chengdu Nan Bo Glass Co., Ltd., which was contracted by our institute, was put into operation and was praised by the owner. After the successful operation, the Ministry of industry and Commerce held a special promotion site to promote the whole industry.
At present, there are nearly more than 30 sets of glass waste heat power generation projects designed and contracted by our institute. Among them, several leading domestic enterprises in the domestic glass industry, such as Nan Bo, Xinyi, Qi Bin and Taiwan glass, have established long-term good cooperation. The more than 60 sets of cement waste heat power generation have created huge economic benefits for the owners, and have also made great contributions to China's environmental protection and energy saving industry.
