Abstract (en)

[origin: JPH10325542A] PROBLEM TO BE SOLVED: To guarantee the optimum injection flow of a burner regardless of variations in a mass flow of cooling air and combustion air. SOLUTION: At least one cooling path 10 is extended into a plenum 13 and formed inside the plenum as diffuser 14 having an orifice 12 into the plenum. At least one of openings 15 and 15' of a burner dome 4 are arranged in the area of the diffuser 14. Bypass paths 16 and 16' having orifices 17 and 17' into the plenum 13 connected on the downstream side of the individual openings. The orifices of the respective bypass paths are turned at least almost parallel with the orifice of the diffuser and formed being shifted in steps outward. Each of the bypass paths has a pressure adjustor.
