Abstract
A bubbling-fluidized bed incinerator and fast fluidized bed incinerator (circulating-fluidized bed incinerator) has been used to incinerate sweage sludge. The multi-purpose fluidized bed incinerator, which has been developed from FFI, is expected to be dealt with dewatered sludge, waste plastic, waste oil, waste liquid and all of industial waste. The operating conditions and operating data obtained from actual plant using multi-purpose fluidized bed incinerator are described in this report.
