PROBLEM TO BE SOLVED: To provide a float external heat type gasification device and float external heat type gasification method in which increment in gasification reaction time and reduction in energy efficiency is prevented to realize high generation efficiency of effective gas component; occurrence of clogging in the device with heat degradation residue is prevented; and frequency of recovery operation for heat degradation residue may be reduced.SOLUTION: There is provide a float external heat type gasification device 1 comprising a gasification reaction part 3 performing gasification of gasification ingredient and an ingredient supplying part 2 supplying gasification ingredient A to the gasification reaction part 3. Also equipped are a residue separation part 4 separating heat degradation residue C which is included in gas B generated in the gasification reaction part 3 and generated in the gasification reaction and a residue recovery part 5 recovering the heat degradation residue C separated by the residue separation part 4 and returns it to upstream side so that heat degradation residue C is re-introduced into the gasification reaction part 3 for re-gasification.SELECTED DRAWING: Figure 1 |
