To provide a boiler system that more efficiently pulverizes biomass, allows the biomass to be easily combusted and can enhance utilization efficiency of a boiler.
The boiler system includes: a boiler body for combusting fuel; an economizer disposed in a path of an exhaust gas exhausted from the boiler body; an air heater disposed downstream from the economizer in the path of the exhaust gas; and a biomass supply unit for supplying biomass as fuel to the boiler body. The biomass supply unit comprises: pulverization means for pulverizing the biomass; a preprocessing unit for supplying the biomass to the pulverization means; and heating means that causes a part of the exhaust gas flowing between the economizer and the air heater to branch off and heats the biomass by performing heat exchange between a branched branch exhaust gas and the biomass present in at least one of the pulverization means and the preprocessing unit.
