Design,manufacture,control and maintenance of high temperature components of heavy duty gas turbine is the core technology. This paper analyzes significance of key technologies principles on safe and highly effective operation of the unit. By analyzing structure characteristics of combustor of MHI F gas turbine,simulation on flow field characteristic of multiple swirl combustor was studied and numerical results indicated that the central recirculation zone was the main mecha-nism of stable combustion of multiple swirl structure. On the above analysis,improvement for characteristics of aerodynam-ic and acoustic design technologies for combustor of MHI F gas turbine were introduced and analyzed. Aiming at combustion oscillation,oscillation mechanism,combustion adjustment,principles of oscillation control and relevant ideas and methods were analyzed for providing references on design for combustor of heavy duty gas turbine and combustion adjustment.
