Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
A COMBUSTION PROCESS FOR PRODUCING A COMBUSTION GAS SUITABLE FOR FEEDING TO A COMBUSTION GAS TURBINE COMPRISING THE STEPS OF BURNING AN EXTRANEOUS COMBUSTIBLE FUEL WITH SUBSTANTIALLY THE THEORETICAL AMOUNT OF A COMPRESSED COMBUSTION-SUPPORTING GAS IN A COMBUSTION ZONE IN THE PRESENCE OF SUB-DIVIDED SOLIDS AT A TEMPERTURE BETWEEN ABOUT 1350* TO 1800* F. AND A PRESSURE OF ABOUT 75 TO 250 P. S. I. G., REMOVING A COMBUSTION GAS FROM THE COMBUSTION ZONE, REMOVING HEAT FROM THE COMBUSTION ZONE BY CONTINUOUS WITHDRAWL OF SUBDIVIDED SOLIDS THEREFROM, ABSTRACTING HEAT FROM THE WITHDRAWAL OF SOLIDS BY CONTACTING THEM WITH A SECOND RELATIVELY COLD COMPRESSED GAS EQUAL IN AMOUNT TO ABOUT 2 TO 6 TIMES THE AMOUNT OF SAID COMBUSTION SUPPORTING GAS, SEPARATING THE COOLED WITHDRAWN SOLIDS FROM THE SECOND HEATED COMPRESSED GAS, AND COMBBINING THE COMBUSTION GAS FROM THE COMBUSTION ZONE WITH THE HEATED COMPRESSED GAS TO FORM A TURBINE GAS MIXTURE HAVING A TEMPERATURE OF AT LEAST 1200* F. AND A PRESSURE OF AT LEAST 75 P. S. I. G.

Claim 3
Dependent Claim
116 words
A COMBUSTION SYSTEM COMPRISING A COMBUSTION CHAMBER FOR THE COMBUSTION OF A COMBUSTIBLE FUEL AND ADAPTED TO CONTAIN FINELY DIVIDED NON-COMBUSTIBLE SOLID PARTICLES IN CONTACT WITH COMBUSTION GASES, MEANS FOR WITHDRAWING COMBUSTION GAS FROM THE COMBUSTION CHAMBER, MEANS FOR INTRODUCING FUEL INTO SAID COMBUSTION CHAMBER, MEANS FOR INTRODUCING COMBUSTION SUPPORTING GAS TO SAID COMBUSTION CHAMBER, A COOLING ZONE SEPARATE FROM SAID COMBUSTION CHAMBER, MEANS FOR INTRODUCING COOLED GAS INTO SAID COOLING ZONE, MEANS FOR CONVEYING HOT FINELY DIVIDED SOLIDS FROM SAID COMBUSTION CHAMBER TO SAID COOLING ZONE, MEANS FOR RETURNING SOLIDS FROM THE COOLING ZONE TO THE COMBUSTION CHAMBER, AND MEANS FOR COMBINING THE WITHDRAWN COMBUSTION GAS WITH THE HEATED GAS WITHDRAWN FROM THE COOLING ZONE.
