Abstract

An apparatus for safely and continuously pyrolyzing organic material, such as contained in municipal waste, in a two-bed pyrolysis system including a pyrolysis reactor and combustion reactor in which several different physical factors influencing the state of fluidization, such as amount of sand in the system, circulation rate of the sand, pressure difference between the free boards of the two reactors and superficial velocity in the pyrolysis reactor, are comprehensively controlled or regulated so as to maintain the operating point of the system at substantially the center of the stable operating range. The feed rate of material charged into the system may also be regulated as required.
