Abstract
The present application provides an alternative fuel fast start system for a gas turbine engine with a combustor and a compressor. The alternative fuel fast start system may include an alternative liquid fuel, a thermal energy storage tank, and a vaporizer. The alternative liquid fuel is stored in the thermal energy storage tank under pressure such that releasing the alternative liquid fuel from the thermal energy storage tank vaporizes the alternative fuel. Upon start-up of the gas turbine engine, the thermal energy storage tank supplies the vaporized alternative fuel to the combustor until the vaporizer is operational. The alternative liquid fuel may be propane, ethanol, or methanol.
