In order to combine the traditional rotary mechanical disturbance characteristic with the inert bed material heat storage properties, a new type of rotary gasifier was designed. On the basis of the new type of rotary gasifier, a staged gasification and combustion experimental platform was designed and the thermal state test of the system was completed. The effects of rotational speed, equivalence ratio, temperature and other parameters on the gasification reaction system were investigated. The experimental results showed that when rotary furnace speed was controlled at 1~4r/min, the rotary furnace mixed disturbance characteristics were enhanced with the increase of rotary speed, and temperature distribution was more uniform in the furnace, different parameters were improved in the experimental range, good gas production was got at rotary furnace speed of 3r/min. When temperature was controlled in the range of 550~700℃, the gasification parameters were increased with the increase of temperature, and gas calorific value and gasification efficiency were affected greatly by temperature. Under the experimental conditions with temperature of 600~650℃, the calorific value of combustible gas, gasification efficiency and other indicators were greatly improved. The equivalent ratio (ER) was changed in the range of0.2~0.4, and it had great impact on gas production of the indicators, with the increase of equivalence ratio, the gas production rate and bed temperature were increased to a certain degree, the change trend of other gasification parameters were firstly increased and then decreased, good gasification results were obtained with ER of 0.3.The typical result showed that gas composition of rotary gasifier was close to that of the fluidized bed, considering the sensible enthalpy, the gasification efficiency was about 79.3% and the carbon conversion rate was about 81.3%. The gasifier energy balance was calculated, and the output efficiency of the system was 86.8%, with heat dissipation as main energy loss way. It was found from the separation of the bottom ash with bed material that about 86% of the total ash content was remained in the bed material area, and more than 90% of it was distributed in the bottom of the bed material area. Experimental results were optimized by controlling the variables for operation and design of new type of gasifier improvement to provide reference.
