<p><P>PROBLEM TO BE SOLVED: To provide a gardening house heater including a wood burning combustion furnace, lowering the maintenance cost using inexpensive solid fuel. <P>SOLUTION: In the wood burning combustion furnace, four cylindrical combustion furnaces 3 having a small diameter, a small height, and a high flame are provided to obtain enough thermal power. Wood waste solid fuel obtained by drying forest residual material and crushing the same to a suitable size is supplied from a fuel feed part 17 through a fuel feeder 18, a fuel feed port 19, the respective branch passages 16 of an exhaust gas press-in side gas duct 12 and a fuel press-in port 15 to the inside of the cylindrical combustion furnaces 2, and burnt in a rising combustion fluidized bed and a turning combustion fluidized bed formed in the furnaces by the air injected from a blowing pipe 32 buried in a furnace wall. Non-combustible part and ash are guided with exhaust gas to a can body 4, an exhaust gas pipe 6 and a gas duct 7, and the non-combustible part and ash separated from the exhaust gas are discharged from a chimney 8, and high-pressure gas body is passed through the exhaust gas press-in side gas duct 12 to be pressed in the furnaces together with fuel. The air in the house, which is blown into the can body 4 and exhaust gas pipe 5 by a heat exchanging blower 26 and subjected to heat exchange, is circulated from the exhaust duct 28 into the house. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
