China's cement kiln waste heat power generation technology has made great progress after nearly ten years of development, and is now close to the international advanced level. A variety of power generation systems have been born to meet the requirements of different kiln types. & nbsp; & nbsp;
What is a waste heat power generation kiln? & nbsp; & nbsp; A secondary waste heat power generation system
adopting a vertical waste heat boiler and a steam compensation type steam turbine generator unit. The vertical waste heat boiler thoroughly solves the problems that the air leakage of the horizontal waste heat boiler and the actual distribution of the temperature field in the boiler are completely different from the assumed temperature when the boiler is designed, and can greatly improve the steam output of the boiler; The waste heat of waste gas of about 200 ℃ discharged by grate cooler or vertical waste heat boiler can be fully recovered and used for power generation. In this way, the waste heat power generation per ton of clinker can be increased to more than 195 kilowatt hours on the premise of unchanged clinker heat consumption, so that the comprehensive energy consumption of the cement kiln can reach the energy consumption level of the same scale precalcining kiln, and the economic benefit is much higher than that of the precalcining kiln. The two-stage waste heat afterburning power generation system of the waste heat power generation kiln not only has the advantages of the two-stage waste heat power generation system, but also can solve the problems of operation safety and environmental protection of the pulverized coal preparation system of the cement kiln. At the same time, it can also solve the problem of power supply for cement plants with other kiln types such as vertical kiln, Lepol kiln, wet kiln and dry rotary kiln in areas with serious power shortage, and can further improve economic benefits.
In order to further promote the green, digital and intelligent development of the cement industry, China Cement Network will be launched on April 24-25, 2023. The " China Cement Industry Green Development Summit Forum and Ultra-clean Emission Technology Exchange Conference " and the " Fourth China Cement Intelligent Summit Forum " were held in Changsha, Hunan Province, inviting industry experts, cement and related enterprises. Jointly promote the high-quality development of the cement industry! After the meeting, we will visit Sinoma Zhuzhou Cement Co., Ltd. and the first set of international "one-box SCR denitrification project of dust and nitrate".
