Technical Field

[0002] Waste heat power generation is a technology that converts excess heat energy in the production process into electrical energy. Waste heat power generation is not only energy-saving, but also beneficial to environmental protection. An important equipment for waste heat power generation is the waste heat boiler. It uses the heat or combustibles in working fluids such as waste gas and waste liquid as a heat source to produce steam for power generation. Since the working fluid temperature is not high, the boiler is large in size and consumes a lot of metal. The waste heat used for power generation mainly includes: high-temperature flue gas waste heat, chemical reaction waste heat, waste gas and waste liquid waste heat, low-temperature waste heat (below 200°C), etc. In addition, there is also power generation using excess pressure difference; for example, the blast furnace gas has a higher pressure at the top of the furnace, and it can be first sent to gas users after power generation through an expansion turbine generator.

[0003] The cement industry is one of the key industries in terms of energy consumption and environmental pollution. Traditionally, it has been produced by burning coal or gas. However, with the improvement of environmental awareness and the adjustment of energy structure, the cement industry is facing the pressure of reducing energy consumption and environmental pollution. Nowadays, people engaged in cement industry technology are committed to research on how to reduce the heat consumption of clinker and the electricity consumption of cement, while people engaged in waste heat power generation technology are committed to research on how to improve the utilization rate of waste heat and increase the amount of waste heat power generation.
