Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
140 words
AN ELASTIC FLUID POWER PLANT COMPRISING IN COMBINATION: AN ELASTIC FLUID TURBINE, A COMPRESSOR DRIVEN BY THE SAID TURBINE AND SUPPLYING THE SAME WITH COMPRESSED ELASTIC FLUID, A REACTION CHAMBER, A COLD HEAT EXCHANGER PASS IN INDIRECT HEAT EXCHANGE WITH THE SAID REACTION CHAMBER INTERPOSED BETWEEN THE DISCHARGE END OF THE SAID COMPRESSOR AND THE ENTRANCE OF THE SAID TURBINE, A BLOWER SUPPLYING A GAS-AIR MIXTURE OF LOW GAS CONCENTRATION, NONCOMBUSTIBLE AT ATMOSPHERIC TEMPERATURE, TO THE SAID COMBUSTION CHAMBER, A ROTARY REGENERATIVE HEAT EXCHANGER TRANSFERRING HEAT FROM THE EXHAUST GASES LEAVING THE SAID REACTION CHAMBER TO THE FRESH GAS MIXTURE ENTERING THE SAME, RAISING THE LATTER TO A TEMPERATURE AT WHICH IT BECOMES COMBUSTIBLE, A BY-PASS LINE SHUNTING ACROSS THE SAID COLD HEAT EXCHANGER PASS OF THE REACTION CHAMBER AND REGULATING VALVE MEANS ARRANGED IN THE SAID BY PASS LINE.

Claim 3
Dependent Claim
112 words
A PROCESS OF OPERATING AN ELASTIC FLUID TURBINE PLANT WITH A METHANE-AIR MIXTURE OF A METHANE-CONCENTRATION BELOW 1% AS A FUEL COMPRISING THE STEPS OF POSITIVELY PASSING A STREAM OF THE SAID METHANE-AIR MIXTURE THROUGH AN EXOTHERMIC REACTION REGENERATIVELY TRANSFERRING HEAT FROM THE BURNT GASES LEAVING THE SAID REACTION TO THE FRESH METHANE-AIR MIXTURE RAISING THE SAME TO A TEMPERATURE AT WHICH IT BECOMES COMBUSTIBLE, COMPRESSING A SEPARATE ELASTIC FLUID, TRANSFERRING HEAT BY INDIRECT EXCHANGE FROM THE SAID REACTION TO THE SAID COMPRESSED ELASTIC FLUID, EXTRACTING MECHANICAL ENERGY FROM SAID COMPRESSED AND HEATED ELASTIC FLUID, AND USING THIS MECHANICAL ENERGY PARTLY FOR COMPRESSING SAID ELASTIC AND PARTLY FOR DRIVING AN EXTERNAL LOAD.
