Calculate heat rate of gas turbine

WebThe repeatable determination of the turbine cycle heat rate also depends on cycle isolation. Since primary flow is measured in the feedwater line, any leakage between the flow measure-ment and the turbine stop valve must be elimi-nated or the test results adjusted accordingly. Otherwise, an erroneous measurement of heat rate will be obtained.
