US 5,205,727 A · Pulse combustor

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 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.

Dependent claims

A pulse combustor for continuous combustion of air/fuel mixture, comprising:

a combustion chamber receiving mixture of air and fuel gas for pulsative combustion;
one or plural tail pipes connecting to said combustion chamber for exhausting combustion byproducts from said combustion chamber;
a mixing chamber being coupled with and connected to said combustion chamber via a first opening provided with a flame trap, for mixing air and fuel gas and supplying the air/fuel mixture to said combustion chamber;
an air chamber being coupled with and connected to said mixing chamber via a second opening formed on a face opposite to said first opening, for supplying air to said mixing chamber;
a fan for feeding air into said air chamber;
and
a gas supply conduit for supplying fuel gas to said mixing chamber, said gas supply conduit going through said air chamber and having one end projecting to connect with said mixing chamber via said second opening;
wherein said second opening is formed eccentrically with respect to said first opening.
