1. A pulse combustion device comprising:
- a plurality of combustors, each comprising a wall surface extending from an upstream inlet to a downstream outlet, the wall surface defining;
a main body portion extending downstream from the inlet; and
a nozzle downstream of the main body portion; and
a plurality of coupling conduits providing communication between the combustors, including for each given combustor;
first communication between a first location upstream of the nozzle of the given combustor and a first nozzle location along the nozzle of a first other of the plurality of combustors; and
second communication between a second location upstream of the nozzle of a second other of the plurality of combustors and a second nozzle location along the nozzle of the given combustor.

Abstract
A pulse combustion device has a number of combustors with upstream bodies and downstream nozzles. Coupling conduits provide communication between the combustors. For each given combustor this includes a first communication between a first location upstream of the nozzle thereof and a first location along the nozzle of another. There is second communication between a second location upstream of the nozzle and a second communication between a second location upstream of the nozzle of a second other combustor and a second nozzle location along the nozzle of the given combustor.

13. A method for operating a pulse combustion device, the device comprising:
-
a plurality of combustors, each comprising;
a wall surface;
an upstream inlet; and
a downstream outlet, the method comprising for each combustor;
discharging gas laterally into the combustor between the inlet and the outlet; and
varying a rate of the discharging during a cycle of the given combustor so as to control a backpressure within the given combustor. - View Dependent Claims (14)
