Abstract
An improved thermal efficiency power plant for converting fuel energy to shaft horsepower is described. The conventional combustor of a gas tubine power plant is replaced by a direct contact steam boiler 8, modified to produce a mixture of superheated steam and combustion gases. Combustion takes place preferably at stoichiometric conditions. The maximum thermal efficiency of the disclosed plant is achievable at much higher pressures than conventional gas turbines. Uses of multi-stage compression turbines (4, 9, 1, 10) with intercooling (2, 3) and regeneration (16, 17, 18, 19) is utilized along with a vapor bottoming cycle (11, 12, 13) to achieve a thermal efficiency greater tha 60% with a maximum drive turbine inlet temperature of 1600 degrees Fahrenheit.
