Fluidized Bed Combustion of Pyrolysis Char of Municipal Waste

Fluidized bed Combustion of the char produced by the pyrolysis of municipal waste was carried out as a part of a new system of energy recovery from the waste.The char particles were continuously fed into a fluidized bed of silica sand particles and were burned under single-stage or two-stage combustion schemes. After the necessary conditions for the stable operation were searched, combustion characteristics were investigated under steady state operation and the analyses of inorganic elements contained in discharged ashes were conducted. The suitable design of commercial plant was discussed on the basis of the obtained date.
