LOW WASTE GAS BOILER SYSTEM WHICH USES THE SOLID FUEL

摘要

PURPOSE: A low-exhaust gas boiler system using solid fuel is provided to reduce the amount of supplied oxygen by circulating exhaust gas to a combustion chamber through a circulating unit. CONSTITUTION: A low-exhaust gas boiler system(100) using solid fuel comprises a burning unit(130), a boiler unit(140), a filter unit(150), an exhaust blower(160), and an exhaust gas circulating unit(170). The burning unit receives vaporized fuel with external air and burns the vaporized fuel. The filter unit is connected to an exhaust port of the boiler unit and filters harmful matter from exhaust gas. The exhaust blower exhausts the filtered exhaust gas to the outside. The exhaust gas circulating unit supplies mixed air of the exhausted exhaust gas and external air to the burning unit.
