Experimental Investigation of Whole Tires and Biomass Mixed Firing in Reverse Burning Fixed-bed Gasifier

The experiment researched on the gasification of the branch straw and whole tires as raw materials in reverse burning fixed-bed gasifier. The results of the process have shown us the temperature in the gasifier heated-up and the efficiency of the gasifier increased. The temperature in the gasifier can reach up to 750°C and the heat value of the gas is 4.86 MJ/m3. The heat value of the gas was 5.34 MJ/m3 and thermal efficiency of the gasifier could reach up to 60.21% when the tire biomass ratio was 44%. The speed of gasification layer is 140 mm/min. ER have great impacts on gasification temperature, gasification is efficient when ER is at 0.3.
