Abstract
An apparatus and system disclosed herein provides detonation wave arrestor including a detonation wave deflector and a burst element. The detonation wave arrestor disclosed herein attenuates and defects the propagation of a detonation wave characterized by a supersonic flame front propagation. The detonation wave arrestor provides deflection of detonation wave towards the burst element. The rupture of the burst element provides venting of hot gases remaining from the detonation, thus providing separation and attenuation of combusted gas residuals. The detonation wave arrestor disclosed herein may be used in a combustible fuel delivery system.
Claims25
An assembly for inhibiting propagation of a detonation wave in a combustible fuel delivery system, the assembly comprising:
- a detonation wave deflector configured to deflect the detonation wave towards a burst membrane, wherein the burst membrane is configured to break in the presence of the detonation wave and configured to at least partially surround the detonation wave deflector;
- and
- a shut-off valve removably attached to the burst membrane, wherein the shut-off valve is configured to stop a flow of a combustible fluid through the assembly upon a rupture in the burst membrane.
A method of inhibiting propagation of a detonation wave in a combustible fuel delivery system, the method comprising:
- locating a flashback arrestor assembly in a path of the detonation wave;
- deflecting the detonation wave from a detonation wave deflector towards a burst membrane that at least partially surrounds the detonation wave deflector, wherein the burst membrane is configured to break in the presence of the detonation wave;
- and
- stopping a flow of a combustible fluid through the flashback arrestor assembly by closing a shut-off valve located in a path of the combustible fluid and removably attached to the burst membrane upon a rupture in the burst membrane.
A detonation wave arrestor, comprising:
- a detonation wave deflector located in a path of a combustible fluid;
- a burst membrane configured to at least partially surround the detonation wave deflector, wherein the burst membrane is configured to allow dissipation of a detonation wave away from the detonation wave deflector;
- and
- a shut-off valve removably attached to the burst membrane, wherein the shut-off valve is configured to stop a flow of a combustible fluid upon a rupture in the burst membrane.
