  • Process for the cooling of an auto-ignition combustion chamber
    Patent number: 5497611
    Abstract: In a combustion chamber which consists essentially of an inflow zone and a combustion zone, the working gases flowing at high temperature into the combustion chamber are mixed with a fuel, in such a way that the latter initiates auto-ignition. Whilst the inflow zone is cooled by effusion cooling, convective cooling is adopted in the combustion zone, the cooling air for the last-mentioned cooling being used at the same time as cooling air for the effusion cooling.
