| 摘要 |
A combustor (10) for a structure with a land based combustion turbine, comprises a generally tubular sidewall (12) having a downstream-mixing zone (34) where a mixture of fuel and air is developed for downstream combustion, said tubular structure further having an upstream primary zone (22) into which air is admitted through sidewall openings to develop an axial airflow for mixing with downstream injection fuel, means (32) for spraying fuel in the form of small rapidly evaporable droptlets generally radially inwardly of the tubular structur through said sidewall (12) at a location between said primary zone (22) and said mixing zone (34) for mixing with the primary air flow, a catalyst (28) is disposed in the combustor tubular structure at the outlet of said mixing zone (34), a plurality of circumferentially disposed air scoops (36) are located in upstream proximity to said fuel spraying means (32) and directed downstream to produce said booster air streams.
