METHOD AND DEVICE FOR ESTIMATING COMBUSTION GAS PROPERTIES USING TEMPERATURE MEASUREMENT

摘要

PURPOSE: A method and a device for estimating the properties of combustion gas using a temperature measurement are provided to reduce manufacturing costs because only temperature measuring work of combustion gas is required. CONSTITUTION: A method for estimating the properties of combustion gas using a temperature measurement is as follows. The real temperature of combustion gas inside a combustor is measured(S1). A temperature estimation value is obtained by calculating the Governing Differential Equations of heat fluid through the assumed properties of the combustion gas(S4). If an objective function value about a difference between the temperature estimation value and the measured real temperature is converged within a determined reference value, the assumed properties are used as real properties(S7). If the objective function value is diverged from the determined reference value, the assumed properties are controlled using optimized algorithm(S8).
