PURPOSE:To provide complete combustion in a solid fuel combustion device using lime and the like as a fuel for indirect heating furnace by a method wherein aeration holes are provided near a grid surface of a side wall of a combustion chamber having a top net, a grid is placed over the grid surface and a suction port is provided to communicate with a thermal conducting pipe at the grid surface. CONSTITUTION:A suction blower 17 is operated to ignited a burner, resulting in that fuel on a grid 11 is ignited and decomposed gas generated by combustion is partially mixed with air and directed toward a net 3. The decomposed gas reaching the net 3 descends the inner surface of a side wall 7 and flows down into a lower part of the grid 11 from between the fuels. Gas reaching the grid 11 is heated under primary combustion at the grid 11 and at the same time dispersed with and mixed with air coming from aeration holes 9 into the upper surface of a grid 10 and then ignited. The combustion gas is sucked from the gas suction port 15 under operation of a blower 17 and then guided to a thermal radiation pipe 16. With this arrangement, it is possible to make a complete combustion. |
