Technology for reducing CO2 emission and desulfurization of kiln exhaust gas by using "external combustion type high temperature calcined carbonate mineral rotary kiln"

With the rapid increase of greenhouse gas emissions led by CO2, environmental problems such as global warming are becoming more and more serious. In this context, the technical measures and application of CO2 reduction in cement kiln are analyzed. The technology of external combustion type high temperature calcined carbonate mineral rotary kiln is introduced. The research and development process of this technology and related equipment is analyzed. The technical scheme and principle of using CO2 emission reduction and desulfurization of kiln exhaust gas by using "external-fired high-temperature calcined carbonate mineral rotary kiln" are mainly introduced. Although this technology has not been practically applied in the cement industry, it can provide useful references in the reduction of CO2 in cement kilns.
