ABSTRACT:
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.
