Control for supercharged vapor generators

Claim 1

IN A COMBUSTION CONTROL SYSTEM FOR A SUPERCHARGED VAPOR GENERATOR TO WHICH FUEL AND AIR FOR COMBUSTION ARE SUPPLIED UNDER PRESSURE AND WHEREIN THE PRODUCTS OF COMBUSTION FROM THE GENERATOR ARE UTILIZED AS THE MOTIVE POWER FOR A GAS TURBINE DRIVING A COMPRESSOR SUPPLYING THE AIR UNDER PRESSURE AND WHEREIN A VAPOR TURBINE IS PROVIDED FOR ASSISTING THE GAS TURBINE IN DRIVING THE COMPRESSOR AND SURPLUS COMPRESSOR OUTPUT IS WASTED, THE OUTPUT FROM SAID COMPRESSOR WHEN DRIVEN SOLELY BY THE GAS TURBINE BEING INSUFFICIENT IN AN INCREASING AMOUNT TO SUPPLY THE AIR REQUIRED FOR COMBUSTION AS THE RATING OF THE GENERATOR DECREASES BELOW A NORMAL RATING AND EXCEEDING THAT REQUIRED FOR COMBUSTION IN AN INCREASING AMOUNT AS THE RATING OF THE GENERATOR INCREASES ABOVE SAID NORMAL RATING, IN COMBINATION, MEANS FOR ESTABLISHING A CONTROL SIGNAL CORRESPONDING TO THE REQUIRED RATE OF AIR FLOW FOR COMBUSTION, MEANS FOR ESTABLISHING A CONTROL SIGNAL CORRESPONDING TO THE ACTUAL RATE OF AIR FLOW FOR COMBUSTION, MEANS UNDER THE CONTROL OF SAID FIRST AND SECOND CONTROL SIGNALS FOR ESTABLISHING A THIRD CONTROL SIGNAL CORRESPONDING TO THE DIFFERENCE BETWEEN THE FIRST AND SECOND CONTROL SIGNALS, AND MEANS OPERATED BY THE THIRD CONTROL SIGNAL FOR INCREASING THE VAPOR FLOW TO THE VAPOR TURBINE AS THE GENERATOR RATING DECREASES BELOW THE NORMAL RATING AND INCREASING THE AMOUNT OF COMPRESSOR OUTPUT WASTED AS THE GENERATOR RATING INCREASES ABOVE THE NORMAL RATING TO MAINTAIN THE FIRST AND SECOND CONTROL SIGNALS EQUAL.
