Abstract
Flashback of flames in premixed combustion systems is avoided by passing premixed fuel and air prior to combustion through a series of two or more nonaligned multi-channel monolith attached in series. The device is useful as a pre-ignition inhibitor, a detonation wave inhibitor and a flashback arrestor protector.
Claims8
An assembly to prevent propagation of combustion comprising;
- a first and a second multi-channel monolith assembled together in series;
- with the channels of said second monolith nonaligned with the channels of the first monoliths, and said channels having a quenching length.
The method of avoiding flame flashback and inhibiting pre-ignition in premixed combustion systems comprising;
- mixing fuel and air in a mixing zone;
- burning said mixed fuel and air in a combustion zone;
- and passing a mixture of fuel and air to combustion through an assembly of two or more multi-channel monoliths, the channels of at least two of said monoliths being nonaligned, said channels having quenching length.
A method of inhibiting propagation of a detonation wave in a combustion system, which comprises a first zone of pre-mixed fuel and air and a following second zone of combustion, which comprises;
- inserting in the system between first and second zones, an assembly comprising a first and a second multi-channel monolith, the channels of said first monolith being mis-aligned with the channels of said second monolith and said channels having a quenching length.
