Abstract

The utility model belongs to the technical filed of domestic furnaces and relates to a coal-fired heating device. The main body structure of the coal-fired heating device comprises a furnace body and a double-layer heating box. A furnace drawer which can be pulled is arranged on the lower portion of the furnace body. A smoke exhausting outlet of the furnace body and a smoke inlet of the heating box are arranged on the upper portion of the furnace body and connected. A smoke exhausting outlet of the heating box is connected with a chimney. Smoke generated by burning coal enters into the bottom of the heating box through the smoke exhausting outlet of the furnace body, heats a heat accumulation chamber and heat preserving materials in an inner cavity of a shell body of the heating box and is exhausted from the smoke exhausting outlet of the heating box. The heat preserving materials absorb heat of soot and gradually radiate so as to improve utilization efficiency of the heat of the soot. The coal-fired heating device is simple in structure, low in production cost and convenient to install and use. The furnace body and the heating box use a split structure and can be individually designed, assembled for use and individually replaced based on the requirement. Exchanging air currents inside and outside the furnace body can be adjusted through a valve of the furnace drawer, a valve of the furnace body and an exhaust fan to meet the requirements for fire of different strength. The coal-fired heating device is suitable for application under all sorts of weather.
