Abstract
A dry non-slug process by fluidized bed was proposed to gasify coal whose ash fusion temperature is higher than 1500℃ with high efficiency. A lab-scale of hot model examination was performed to evaluate the performance of coal decomposition gasification in fluidized bed under a higher temperature level than 800℃. The gasification could take place successfully without forming clinker in the bed. The knowledge on the gas yield and the composition was studied, and tar emission was decreased with rise in bed temperature.
