The present invention relates to a boiler using sawdust and a pellet fuel capable of preventing environmental pollution by supplying hot water by using sawdust and a pellet as a fuel of a boiler rather than coal or oil. The boiler using sawdust and a pellet fuel comprises: a main body which includes a space in which a heating unit is installed, includes a smoke pipe discharging smoke generated in the main body to the outside, includes a discharging unit, which discharges ashes piled up after combusting a fuel of sawdust and pellet injected into the main body, on a lower part thereof, and includes a fuel injector coupled thereto to inject the fuel; a heating unit which includes a combustion chamber installed in the main body and performs heating using heat generated when combusting the fuel in the main body, is divided into an inner container and an outer container, includes multiple circulation pipes heated by circulating water, which is introduced through an external cooling water pipe connected between the outer container and the inner container, inside the inner container, and discharges the water through a hot water pipe connected with the circulation pipe; a combusting unit which is coupled on the front surface of the main body by a hinge, is opened and closed by being rotated, and includes a combustor combusting the fuel by receiving the fuel in a part inserted into the main body, a fan introducing outdoor air into the combustor and coupled on the front surface thereof, and an igniter igniting the fuel injected into the combustor; and a control unit which controls the fan of the combusting unit, the fuel injector, and an igniter with a control signal by comparing a sensing signal of a temperature sensor installed in the heating unit of the main body or a sensing signal of a light sensor installed close to the combustion. |
