Abstract
Non-isothermal combustion experiments of different additive amount of biomass char (0,20,40,60,80,100 wt%) at heating rates of 5, 10 and 20 K/min were conducted by synthesized thermogravimetry analyzer(STA409PC) from room temperature to 900°C in air atmosphere. The changes of combustion characteristic parameters of pulverized coals in different conditions were analyzed. The results obtained from TG and DTG curves showed that the combustion process could be divided into three stages, and DTG curves of coal combustion moved to low temperature zones when the amount of biomass char increased which indicated that both ignition and burnout combustion temperature were lower. The burnout time tended to decrease and the combustion characteristic index increased obviously which mean that the combustion performance of pulverized coals with different additive amount of biomass char were improved.
