煤基费托航空燃料燃烧性能及航程

航空替代燃料肩负着能源安全以及环境保护的双重使命。对煤基费托航空燃料的基础燃烧性能及航程进行了实验和理论研究。针对民航客机典型飞行任务，选取装有2台CFM56-7B发动机的B737-800型客机进行全包线飞行的航程评价。研究结果表明，煤基费托航空燃料比石油基航空煤油密度低，但热值高。评价结果表明使用煤基费托燃料的客机航程比使用石油基航空煤油的客机缩短2.1%。同时，虽然煤基费托航空燃料的燃烧边界较石油基航煤略窄，但更易点火且不易积碳。取得的结果对煤基费托航空替代燃料的实际应用具有一定的指导意义。

Combustion performance and range of coal-based Fischer-Tropsch aviation fuel

Aviation alternative fuels play an important role in energy security and environmental protection. Coal-based Fischer-Tropsch synthetic fuel was chosen to experimentally study its basic combustion performance and evaluate the influence of flight range compared to theretical study. A B737-800 with two CFM56-7B engines was chosen to evaluate flight range in full envelope range in a civil aircraft typical mission. The study results show that the coal-based Fischer-Tropsch synthetic fuel has lower density and higher calorific value than petroleum-based aviation kerosene. The evaluation results show that the coal-based Fischer-Tropsch synthetic fuel's lower density and higher calorific value lead to its range shortened by 2.1%. Although Fischer-Tropsch synthetic fuel's combustion boundary is narrower, it performs better in ignition and coking than petroleum-based kerosene. The results obtained has certain directive significance to the practical application of the Fischer-Tropsch alternative fuel.
