PREMIXED COMBUSTOR WITH FLASHBACK ARRESTORS

摘要

A flashback arrestor for a combustion turbine is disclosed. In accordance with the present invention, an area between the combustion zone of the turbine and fuel pre-mixing passages is provided with a structure comprised of a plurality of tubes. The flashback arrestor can thus be described as a "honeycomb" structure, and each individual tube or element of the honeycomb has a diameter that is less than the critical diameter below which flames will not propagate for a particular fuel-air mixture.
