摘要：The ash fusion characteristics and co-gasification activities of different biomasses (corn straw (CS), rice straw (RS) and rice husk (RH)) are investigated in an ash fusion temperature (AFTs) analyzer and a thermo-gravimetric analyzer (TGA). Moreover, the transformation behaviors of mineral matters during CS/RH and RS/RH co-gasification processes are calculated by FactSage software. Results show that the ash fusion characteristic temperatures (AFTs) of CS/RH and RS/RH mixtures both increase with increasing RH ratio, and the maximum ratio of 75% CS and 55% RS in CS/RH and RS/RH mixtures can avoid the melting and slagging problems during co-gasification processes. Under the desirable RH ratio, the gasification activities of CS/RH and RS/RH mixtures increase with increasing CS or RS ratio. Besides, the increased AFTs of CS/RH and RS/RH mixtures are mainly ascribed to the increased contents of high-melting point quartz [SiO2] and tridymite [SiO2] and the decreased content of low-melting point silicate with the increase of RH ratio.
