The pyrolysis characteristics of solid waste are analyzed theoretically. It is point out that the pyrolysis temperature is a primary influence factor. An experimental study on pyrolysis of garbage mixture and waste plastic by using a small externally heated fixed-bed waste pyrolysis furnace is made. The gas production rate and accumulative gas yield of two kinds of wastes at 700 ℃ are obtained. The comparative analysis indicates that the pyrolysis of waste plastic is faster, and its maximum gas production r...
