PULSATING COMBUSTION DEVICE Russian patent published in 1995 - IPC

FIELD: power engineering. SUBSTANCE: pulsating combustion device has combustion chamber 1 with closed rear end and outlet nozzle 2, perforated fuel feed pipe 3 with side holes 4 placed along combustion chamber on its closed rear end and communicating with combustion chamber 1 through fuel pipe connection 6 in vicinity of its outlet nozzle 2; it also has ignition torch 9 mounted in supply pipe. In addition, device is provided with perforated fuel feed pipes 3 having outlet holes 5 part of which are arranged along chamber on its closed rear end and other part of holes, on side of outlet nozzle 2. These fuel feed pipes are arranged in staggered manner and their outlet holes 5 are facing each other. Distribution chambers 8 are located between fuel feed pipes 3 and fuel pipe connection; outlet nozzle 2 is made in the form of corrugated tube whose section varies depending on pressure of gas-fire jet. Cross-shaped vortex agitator is mounted in chamber 1 on fuel feed pipes 3 along its center line. EFFECT: improved exhaust power at same size of device and amount of fuel supplied. 2 cl, 2 dwg
