DEFINITION OF GAS TURBINE SUCTION MASS FLOW RATE

摘要

FIELD: physics, control.SUBSTANCE: set of inventions relates to determination of gas turbine suction mass flow rate. Proposed method allows definition of suction mass flow rate with the help of turbine inlet pressure. Pressure losses in combustion chamber and that between ambient medium and compressor inlet are used as input parameters. Determination is executed without solution of energy balances and without data on fuel calorific value and that on fuel mass flow rate. Note here that preliminary magnitude for suction mass flow rate is determined for every input parameter. Note also that for every preliminary value defined is appropriate magnitude checked validity by cross comparison with appropriate other preliminary data. Note that characteristic parameter as a mean magnitude is generated for gas turbine mass flow rate from data checked for validity.EFFECT: reliable forecast of expected power gain.17 cl, 3 dwg
