HAD-HRSG ] Heat Recovery Steam Generator

This program is called HAD-HRSG, which is a program to design a heat recovery steam generator for high-temperature exhaust gas or waste gas at the exhaust of gas-turbine. The program can calculate the following contents.

Flue gas conditions : Weight or volume type
Evaporator : 3-pressure type, Bare tube/Solid finned tube/Serrated finned tube
Superheater : 1st, 2nd and 3rd superheaters with Reheater, Bare tube/Solid finned tube/Serrated finned tube
Economizer : 3 modules economizer, Bare tube/Solid finned tube/Serrated finned tube
Deaerator : Integral / External type
Detail information of Thermal calculation
Detail information of heat transfer
Detail pressure drop of gas side/water side
Detail information of Max. temperature of tube/fin metal tubes
Geometry information
Noise analysis
ASME tube thickness (ASME section I)
Acid dew point
Heat losses of surface for HRSG
Fresh air and argumenting air firing conditions for duct burner
Heat flux of per bank tubes for evaporator
Natural water circulation (separate one)
Vibration analysis

C is a fitting constant that is a function of the stiffness ofthe system, and the pitch-to-diameter ratio of the tube array.
The Connors criterion provides a suitable stability map with adistinct boundary between stable and unstable flow. However, a
look into the literature shows a large scatter around the suggested stability boundary fixed by the ASME boiler code at C=3

SPL is sound pressure level,which is dependent on the
distance and environment and is easily measured with a
sound level meter. SPL values should be referred to
distance.PWL is sound power level and is a measure of
the total acoustic power radiated by a given source.
PWL is a constant for a given source and is independent
of the envirnment.It cannot be measured directly but
must be calculated.
