VDI 4670 BLATT 1

Thermodynamic properties of humid air and combustion gases

active, Most Current
Organization: VDI
Publication Date: 1 April 2016
Status: active
Page Count: 34
ICS Code (Thermodynamics in general): 17.200.01
scope:

This standard applies to the thermodynamic design of components in energy and process installations with humid air and combustion gases, such as steam generators, gas turbines, industrial furnaces and driers.

This standard makes possible:

• to reproduce as accurately as possible the thermodynamic behaviour of the process gases within the entire region of interest when taking into consideration the technological developments to be expected

• to demonstrate the influences of dissociation, of real-gas behaviour and of condensation which limit the accuracy of the simple models, and, where necessary, to include such influences

• to optimize the formulation of the equations with regard to accuracy and calculating speed

• by means of comparisons to demonstrate the shortcomings of popular physical property models so as to make users aware of the necessity for a common database of sufficient accuracy

Purpose of this standard is not the estimation of the composition of gas mixtures. For the calculation of the composition of humid air and combustion gases an example may be found in VDI 2048 Part 3.
