A combusting apparatus of the present invention can easily recharge an incorporated storage battery that has been exhausted to or below a required minimum level. A burner (18) in the combusting apparatus is further provided with a thermoelectricity generating element (4), which receives the heat of combustion and generates a thermoelectric e.m.f. When a multi-contact switch (16) is activated to set the arrangement of plural capacitors (15) in parallel, the capacitors (15) having the parallel configuration are charged with a thermoelectric e.m.f. generated by the thermoelectricity generating element (4). When an operation of a switching button (20) activates the multi-contact switch (16) to change the arrangement of the capacitors (15) from the parallel configuration to the series configuration, the sum of the voltages of the capacitors (15) is applied to an oscillation circuit (9) included in a booster circuit (8) as well as a storage battery (12). The booster circuit (8) is then activated to boost the thermoelectric e.m.f. generated by the thermoelectricity generating element (4) and start applying the boosted voltage to the storage battery (12). This enables the exhausted storage battery (12) to be efficiently recharged with the power supplied from the capacitors (15) and the booster circuit (8).

The present invention provides a simply constructed, improved pulse combustor realizing stable pulse combustion with less noise and vibration. The pulse combustor includes: a combustion chamber; a mixing chamber coupled with the intake side of the combustion chamber via a first opening provided with a flame trap; and an air chamber connecting to the mixing chamber via second opening. The second opening is eccentric with respect to the first opening. The fuel gas and air are simultaneously supplied through the second opening to the mixing chamber, sufficiently mixed in the mixing chamber, and fed into the combustion chamber. The exhausted gas flown back through the flame trap is diluted with the air/fuel mixture in the mixing chamber and again fed into the combustion chamber for continuous combustion while the reverse pressure is efficiently reduced by the mixing chamber and the air chamber.

Pulse combustor

The present invention provides a simply constructed, improved pulse combustor realizing stable pulse combustion with less noise and vibration. The pulse combustor includes: a combustion chamber; a mixing chamber coupled with the intake side of the combustion chamber via an opening provided with a flame trap; a gas supply conduit connecting to the mixing chamber for supplying fuel gas; and an air duct connecting to the mixing chamber for supplying air. The total volume of the mixing chamber, the gas supply conduit, and the air duct (the total volume V2) is sufficiently greater than the volume of the combustion chamber (the combustion volume V1). Combustion byproducts flown back through the flame trap are diluted with the air/fuel mixture in the mixing chamber and again fed into the combustion chamber for continuous combustion while the reverse pressure is efficiently reduced by the total volume V2.
