ABSTRACT:
The object of the invention is to provide a novel combustion chamber which has an improved air supply and also ensures an optimum incident flow to the burners when the mass flows of cooling and combustion air are different. According to the invention, this is achieved in that the at least one cooling duct (10) is extended right into the plenum (13) and is formed inside the plenum (13) as a diffuser (14) having an orifice (12) leading into the plenum (13). The at least one opening (15, 15') in the burner dome (4) is arranged in the region of the diffuser (14) or directly downstream of its orifice (12). A bypass duct (16, 16') having an orifice (17, 17') leading into the plenum (13) follows downstream of each opening (15, 15'). The orifice (17, 17') of each bypass duct (16, 16') is oriented at least approximately in parallel with the orifice (12) of the diffuser (14) and is also designed so as to be offset step-like to the outside. Each bypass duct (16, 16') is provided with a pressure-regulating device (18, 18').
