摘要：

The TG-DTG thermal analysis technology is applied to simulate the combustion characteristics of corn stover and pulverized coal in boiler atmosphere at different heating rates. The Flynn-Wall-Ozawa method used to establish a dynamic model, researched the combustion characteristics and kinetics of corn stover and its blended coal combustion under simulated boiler atmosphere. The combustion conditions under the same experimental conditions were compared with the air condition. The results show that the comprehensive combustion characteristic index SN doubles with the heating rate, and is halved as the proportion of pulverized coal is doubled. As the proportion of blended coal increases, the fixed carbon combustion stage on the DTG curve gradually splts into two weight loss peaks, and the degree of division in the simulated boiler atmosphere is more obvious. The incorporation of pulverized coal will increase the apparent activation energy fluctuation required in the combustion process. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
