A COMPUTATIONAL STUDY OF SOME OF THE IMPLICATIONS FOR GAS TURBINE DESIGN AND MAINTENANCE AS A CONSEQUENCE OF NO

As permitted levels of NO are progressively reduced, there will be implications not only for engine and combustor design, but also for maintenance practices. Whilst design aspects have received considerable attention, the consequences upon engine maintenance have been largely ignored. Current maintenance practices may have to be reconsidered if engine degradation and fouling, at levels which do not require corrective maintenance were to significantly increase NO production. As different engine cycles and combustor designs will respond differently to NO, generation as a consequence of engine degradation, the maintenance aspects will be of concern not only to engine users, but also to engine designers. This paper is an initial attempt aimed at identifying the importance of the interacting, complex considerations between design, engine degradation, operation and level of NO generation. Such a study requires access to an interactive combustor design and performance analysis programme. The paper also briefly describes a user friendly combustor program developed at Cranfield and its application.
