Regenerative gas turbine power plant
Abstract
Abstract THIS INVENTION IS DIRECTED TO REGENERATIVE BRAYTON CYCLE GAS TURBINE POWER PLANTS OF EITHER THE INTERNAL COMBUSTION TYPE OR THE CLOSED CYCLIC TYPE WHEREIN THE COMPRESSED INTAKE FLUID STREAM IS PRE-HEATED THROUGH CONTACT INTERCHANGE IN PARALLEL FLOW WITH HOT LOW-PRESSURE TURBINE EXHAUST GASES WITHIN VELOCITY-ACCELERATED CONTACT-TYPE HEAT EXCHANGERS. THIS INVENTION IS ALSO DIRECTED TO EXHAUSE-FIRED GAS TURBINE POWDER PLANTS WHEREIN THE COMPRESSED INTAKE FLUID STREAM IS HEATED THROUGH CONTACT INTERCHANGE IN PARALLEL FLOW WITH HIGH-TEMPERATURE TURBINE EXHAUST GASES DIRECTLY FOLLOWING THE COMBUSTION PROCESS WITHIN VELOCITY-ACCELERATED CONTACT-TYPE HEAT EXCHANGERS SO AS TO LIMIT BOTH TURBINE INLET TEMPERATURES AND THE FOULING OF TURBINE BLADE SURFACES. .
