Experimental study and analysis on combustior efficiency with diesel fuel

Aero-gas turbine technology often needs to be improved for power of ground. In order to solve the problem of low combustion efficiency after the change of diesel fuel under the low condition, the gas sampling was used for the combustion efficiency measurement at different inlet air temperature, air flow rate and fuel air ratio. Experimental studies have shown that combustion efficiency falls sharply at low fuel-air-ratio with low combustion temperature and it is gradually close to 100% with the increasing of fuel-air-ratio. And combustion gets more adequate with the increasing of the inlet air mass flow rate and temperature by improving the atomizing ability and combustion temperature. Combustion efficiency increased from 96% to 99% above. The combustion efficiency forecast empirical formulae is summarized for diesel fuel.
