舰船燃气轮机的额定功率及燃油消耗率等性能指标通常是在无进排气全压损失或在给定的全压损失下给出的。在实际使用中,当进排气道的全压损失与给定值不同时,燃气轮机的性能将发生变化,这常常是不可忽视的。如英国苔茵 RMIA 燃气轮机进气阻力增加1%时,功率下降2%,油耗增加1%.在诜择燃气轮机、鉴定机组性能、设计讲排每装置及研究 COGAS 装置时,都
Performance indicators such as the rated power and fuel consumption rate of a ship gas turbine are usually given at full pressure loss without intake or exhaust or at a given total pressure loss. In actual use, when the total pressure loss into the exhaust port is different from the given value, the performance of the gas turbine will change, which is often not negligible. For example, when the intake resistance of the British Tundra RMIA gas turbine is increased by 1%, the power is reduced by 2% and the fuel consumption is increased by 1%. When selecting gas turbines, identifying unit performance, design layout and COGAS installation,
