TEMPERATURES IN A GAS-TURBINE VAPORIZER AT NEAR IDLE ENGINE CONDITIONS

The work is a laboratory investigation of the effect of different liqu id flow rates on the metal temperature of a gas turbine T vaporizer. M ost of the experimentation was carried our using JP5. A limited number of number of runs using Diesel Fuel Marine and calibration runs using water provided additional data for different fluids. Conditions that approach local liquid depletion inside the vaporizer were identified b y monitoring local overheating of the vaporizer metal. Because of appa ratus limitations, testing was carried out only at vaporizer pressure and liquid flow rates approaching idle engine operation. An experiment al correlation was developed allowing estimation of the mean vaporizer temperature as a function of input conditions and fluid properties.
