主权项

1. A solid fuel boiler for receiving and combusting a solid fuel supplied from an exterior to heat a hot water and a heating water, the solid fuel boiler comprising:
a combustion furnace including an open top portion, provided therein with an inlet port in which the solid fuel is introduced and an outlet port for exhausting ash created by combusting the solid fuel, and combustion gas being exhausted to the open top portion; a plate part located inside the combustion furnace so that the solid fuel supplied into the inlet port is positioned on the plate part to be combusted; two fuel supply parts for supplying an oil fuel and a gas fuel to an inside of the combustion furnace, respectively; a boiler part located at an upper portion of the combustion furnace to heat the hot water and the heating water by heat generated by combusting the solid fuel; and a connection part for connecting the combustion furnace with the boiler part, wherein the connection part comprises a water jacket which is formed therein with a connection hole being vertically open, the upper portion of the combustion furnace being coupled with an inner side of the connection hole, and a receiving space being formed at an outer side of the connection hole and including an open top portion at an inner side of the water jacket, the water jacket is connected to a heating water introduction pipe in which the heating water from the exterior is introduced into the receiving space, and wherein the boiler part comprises: a casing formed therein with a plurality of exhaustion holes communicating with the connection hole, a storage space communicating with the receiving space and being formed at an inner side of the casing so that the heating water from the receiving space is introduced into the storage space, and a heating water exhaustion pipe for exhausting the introduced hot water, being connected to the casing; and a hot water pipe where cool water is introduced to a first end of the hot water pipe and exits through a second end of the hot water pipe so that the cool water is heated to exhaust a hot water, the storage space being disposed between the first and second ends of the hot water pipe.
