For enthalpy (FMAPx=106) and heat flow (FMAPx=107)
Provides the enthalpy or heat flow that a fluid with the same composition would have at the same pressure and temperature when calculated according to FDBR (classic stream type).
This is used to simplify auxiliary constructions in which energy balances between different stream types are to be mapped.
For the time being, only the most common case has been implemented, namely water or steam on the one hand and air (FDBR only), flue gas, fuel gas, raw gas, coal, oil or user-defined fluid on the other.
Previously, an auxiliary stream of the latter line type had to be modeled for the energy balance, with 100% water as composition and the same pressure and temperature as the water stream.
