Abstract
A double fluidized bed reactor system including a staircase-type helical blade is proposed. The system includes a bubbling fluidized bed gasification furnace for receiving fuel (for example, combustible waste and biomass) and steam, forming a bubbling fluidized bed through a flow of flow medium therein, and gasifying the fuel, thereby generating a resultant gas, and a high-speed fluidized bed combustion furnace for receiving char of the resultant gas and the flow medium from the bubbling fluidized bed gasification furnace, additionally receiving air, combusting the char so as to heat the flow medium, and transferring the heated flow medium back to the bubbling fluidized bed gasification furnace.
