Research and application of alternative fuel swirl combustion and low-temperature gasification combined process in cement kilns
In order to improve the fuel substitution rate of the cement kiln and reduce the impact of using alternative fuels on the burn-ing system,this paper proposed a combined process of alternative fuel swirl combustion and low-temperature gasification outside the cement precalciner followed by furnace combustion.Taking a cement production line using RSP cement precalciner as an example,this process plan and application effect were introduced.The results shown that the TSR(thermal substitution rate)of the cement line can reach 36％(using waste spinning),and the sintering system operated stably.The process system was simple,flexible in layout,and required minimal investment.By reasonably controlling the quality of alternative fuels and optimizing system operations,the com-bined process achieved good coal saving and carbon reduction effects.
