Thermal properties of flue gas
The thermal properties for flue gas used in these procedures are curve fits of the following families of curves. The source for these curves is not currently known, as they were originally constructed some thirty years ago as we were developing some of the software proceedures presented herein. However, the reliability of these values seem to be very suitable for HRSG design.
Below is a JavaScript calculator which can interpret these curves.
