Abstract: In a gas turbine combustion chamber cooled by means of impingement and convection cooling or pure convection cooling, a compensating flow of the cooling air is guided between adjacent cooling ducts (2) in such a way that the flow velocity in the cooling duct (2) always exceeds a critical limiting value even downstream of a local damage location (6) so that the temperature is less than a critical limiting value. The compensating flow is led past the combustion chamber outer wall. Connecting openings (5) are arranged between adjacent cooling ducts (2) and are respectively offset on the opposite sides of the cooling duct (2).

Abstract: A combustor effective for reducing exhaust emissions is disclosed. The combustor includes first and second liners defining a primary combustion zone, and a plurality of circumferentially spaced carburetors. Each of the carburetors includes a fuel injector providing fuel into an air swirler for mixing the air and fuel and providing a fuel/air mixture into the combustor primary zone. The combustor also includes means for obtaining a fuel distribution from each of the carburetors extending radially from a first liner upstream end through a center region of the combustor to a second liner upstream end with values of the fuel distribution at the center region being generally no greater than about values of the fuel distribution adjacent to at least one of the first and second liners. The first and second liners have upstream portions characterized by the absence of film cooling thereof.

Abstract: A combustor of a gas turbine having a double wall construction in one part of the combustor, wherein an outer plate is formed with a multiplicity of cooling air inlet apertures and an inner plate is formed with a multiplicity of cooling air outlet apertures. The inner and outer plates are connected together by a multiplicity of connectors formed of heat conductive material and define therebetween a space. The cooling air inlet apertures are greater in diameter but smaller in total area than the cooling air outlet apertures which are inclined at an angle of 30 degrees. Cooling air introduced into the space through the cooling air inlet apertures impinge on the inner surface of the inner plate and performs impinge cooling while the connectors perform pin fin cooling. The cooling air also performs film cooling as it flows along the outer surface of the inner plate after cooling the walls of the cooling air outlet apertures while being released.

Abstract: The disclosure is of a combustion chamber having prevaporizing pipes for the injection of fuel and shield cups intended to play the role of thermal barriers, upon which the hot jets issuing from the injectors are broken up. The shield cups have ribs toward which high velocity jets of air are directed, the jets of air issuing from small orifices. Other small orifices may addtionally open on a ridge of the ribs, so as to form supplementary jets of air convergent with the first set of jets of air.
