Abstract
A power plant comprises a free piston gas generator having compression chambers and motor cylinders. A reciprocable assembly has drive pistons which are slidably received in the motor cylinders and compression pistons, each slidable for defining a variable volume compression chamber. A rotary compressor delivers air at above atmospheric pressure to the compressor chambers which are distributed into a first set and a second set. The outlets of the first set deliver air to the motor cylinders. The second set delivers pressurized air to the exhaust gas and the mixture is admitted into a power gas turbine. The temperature of the mixture of hot air and exhaust gas is increased before delivery to the turbine by a heat exchanger and a compression chamber.
Claims10
A power unit comprising:
- a free piston gas generator having a plurality of compressor chambers, motor cylinder means, and a reciprocable assembly having drive piston means slidably received in said motor cylinder means and a plurality of compression pistons cooperating with said compression chambers, whereby reciprocation of said assembly alternately increases and decreases the volumes of said compression chambers,
- a power gas turbine connected to receive a flow of exhaust gas from an exhaust of said motor cylinder means,
- a rotary compressor connected to said compression chambers through first cooling means to deliver air at chambers through first cooling means to deliver air at above atmospheric pressure to said compressor chambers,
- said compressor chambers being distributed into a first set and a second set with outlets of the first set of said compression chambers being connected to deliver air to said motor cylinder means through second cooling means and outlets of the second set being connected to deliver hot pressurized air to said flow of exhaust gas prior to admission to said power gas turbine, whereby said exhaust gas and hot air mix before delivery to the turbine,
- and heating means for increasing the temperature of the mixture of hot air and exhaust gas before delivery to the turbine.
