BOILER FOR SOLID FUEL AND COMBUSTION APPARATUS

摘要

PURPOSE: A boiler for solid fuel and a combustion device thereof are provided to improve the durability of a fuel feeder and prevent the deformation even in a long-time use. CONSTITUTION: A combustion device(10) of a boiler for solid fuel comprises a rotary shaft(12), a plurality of fuel feeders(14), and supporting units(16,17). The rotary shaft passes through the combustion chamber of a boiler and is rotated with the power of a driving source. The fuel feeders are rotated with the rotary shaft so as to transfer solid fuel and discharge the sludge and ash produced during the combustion of the solid fuel. The supporting units connect and support the rotary shaft and the fuel feeders. A space is formed in each fuel feeder so that the fuel feeder is connected to the supporting units and cooling water is supplied.
