Abstract:
A method of treating combustibles, said method comprising:circulating a fluidized medium between a combustion region and a heat recovery region within a bed of a fluidized-bed furnace such that said fluidized medium is heated in said combustion region; gasifying combustibles in said combustion region of said fluidized-bed furnace, thus generating combustible gas and non-combusted particles; recovering heat from said fluidized medium in said heat recovery region of said fluidized-bed furnace after said fluidized medium has been heated in said combustion region, so as to thereby control a temperature of said bed; and delivering said combustible gas and non-combusted particles to a melt combustion furnace and therein combusting said combustible gas and melting non-combustible ash of said non-combusted particles.
