<p>A combustion gas generator comprising a vertical furnace (102) and stacks (307, 510) connected with the vertical furnace (102) via an induction blast machine (305). The vertical furnace (102) comprises a fuel charging unit (127) provided at the upper portion thereof, for allowing biomass-based combustible materials to be charged, a hollow fire grate (103) provided in the vertical furnace and having a plurality of secondary air jetting holes (104), a primary air supply pipe (106) connected above the fire grate with the vertical furnace, secondary air supply pipes (107, 123) connected below the primary air supply pipe with the vertical furnace or the fire grate, a tertiary air supply pipe (108) connected below the fire grate with the vertical furnace, a high-temperature combustion gas exhaust pipe (109) connected below the fire grate with the vertical furnace, and an ash-pit (112) provided at the bottom of the vertical furnace, wherein those portions of the side walls above the fire grate are formed to have downwardly diverging slopes with respect to the vertical surface, and the high-temperature combustion gas exhaust pipe is kept integrated via the induction blast machine for connection with the stacks.</p> |
