GASIFICATION METHOD

PROBLEM TO BE SOLVED: To provide a gasification method by which biosludges can be efficiently gasified. SOLUTION: In a power generation system 100, a sewage sludge is solubilized by solubilization equipment 10 which uses a cavitation treatment method or the like and dehydrated by a dehydrator 20 to...

Summary:PROBLEM TO BE SOLVED: To provide a gasification method by which biosludges can be efficiently gasified. SOLUTION: In a power generation system 100, a sewage sludge is solubilized by solubilization equipment 10 which uses a cavitation treatment method or the like and dehydrated by a dehydrator 20 to reduce the water content to about 55%, then, it is partially incinerated by a fluidized gasification furnace 30 which is improved in carbon conversion ratio by maintaining the air ratio at about 0.45 and the sand layer temperature of a fluidized bed 32 at the range of 900 to 1,000 °C by blowing-in of a primary air heated with a burner 41, and the gas gasified in the fluidized gasification furnace 30 is utilized for power generation at a power generator 70 such as a gas engine.
