The application prospect of pure low-temperature waste heat power generation in the glass industry is promising.

the glass industry is a major energy consumer. At present, the domestic flat glass industry mostly adopts the production technology of float glass. There are about 160 float glass furnaces, and the process level has been comparable with the international level. However, there is still a large gap in energy consumption compared with the international advanced level. The average heat consumption of glass production is about 20% higher than the international advanced level. The waste heat from the flue gas of the glass production line has not been well recycled. For example, the waste heat from the flue gas of a 500t/d float glass production line can generally produce saturated steam of 7 ~ 8t/h. Besides being used for heating in winter, a small amount is used to heat heavy oil, a large amount of steam is wasted. Therefore, China's glass industry has great potential for energy saving and consumption reduction. Using pure low-temperature waste heat power generation technology to build power stations is an effective measure to achieve energy conservation and emission reduction. The pure low-temperature waste heat power generation technology of glass melting furnace refers to the use of a large amount of 300 ℃ ~ 500 ℃ low-grade waste gas waste heat resources discharged during the production of float (LOFA) glass, the heat exchange is carried out through the waste heat boiler, the waste gas waste heat is recovered to generate superheated steam, the low parameter steam turbine unit is promoted, the generator is driven to generate electric energy, and the conversion from heat energy to mechanical energy is realized. This is a high-level comprehensive utilization of waste gas and waste heat from glass furnaces. It is an energy-saving, emission reduction and comprehensive resource utilization technology advocated and encouraged by the state. The application of pure low temperature waste heat power generation technology in the cement industry has been relatively mature

after Jiangsu Zhangjiagang China Resources Group established the first low-temperature waste heat power plant of float glass in China, which is Bayer's largest production base in the United States, Hubei Sanxia New Material Co., Ltd. and Dongguan Xinyi Glass Co., Ltd. also established low-temperature waste heat power plants. After all, this technology has just started in the glass industry. In order to provide a better exchange platform for the glass, cement, ceramics, steel and other industries, and better promote the application of pure low-temperature waste heat power generation technology in float glass production lines, the fifth pure low-temperature waste heat power generation international summit hosted by China cement will be held in Shanghai on March 26. At that time, experts in the field of waste heat power generation at home and abroad, celebrities in glass, cement, ceramics, steel and other industries and representatives of large enterprises will be invited to discuss the application and development of pure low-temperature waste heat power generation technology and introduce the successful application experience in the cement industry. Pengshou, member of the Executive Committee of the International Glass Association, chairman and general manager of China Building Materials International Engineering Co., Ltd. and President of Bengbu Glass Industry Design and Research Institute, will be specially invited to the summit to introduce the practical application of low-temperature waste heat power generation technology in the industry of improving and industrializing the technology of basic materials in measuring the length between the gauge of broken specimens with vernier calipers on key bases
