Document Type and Number:
WIPO Patent Application WO/2024/034349
Kind Code:
A1
Abstract:
Provided is a boiler system (100) comprising: a biomass mill (10) that grinds a biomass fuel; a boiler (20) that combusts the biomass fuel ground by the biomass mill (10) in a combustion device (22) to generate vapor; an air preheater (30) that heats air by means of exhaust gas discharged from the boiler (20); a first air supply path (50) that supplies the heated air heated by the air preheater (30) to the biomass mill (10); a first branch supply path (51) that branches part of the heated air from the first air supply path (50); and a furnace bottom ash processing facility (40) for using the heated air supplied from the first branch supply path (51) to dry a non-combusted biomass fuel discharged from the boiler (20), and supplying the resultant to the combustion device (22) again.
