【Abstract】 During the operation of a dual fuel fuel chamber, the deterioration of combustion chamber performance is prone to occur during the mixed combustion process of gas/liquid fuel. This paper uses numerical simulation methods to study the fuel switching process of a dual fuel gas turbine combustion chamber used on offshore oil and gas platforms, and analyzes the impact of gas/liquid fuel ratio on the conventional performance of the combustion chamber during the fuel switching process under three switching strategies. The differences in performance fluctuations during fuel switching under different fuel supply strategies were compared, and a stable switching control strategy was obtained. Finally, the fast opening type was selected as the optimal switching strategy, and the rationality of the strategy was verified through full process switching simulation.更多还原
