Steam Module

The Steam module allows you to perform simulations of pipeline networks carrying steam in the supply pipes. The module assumes superheated steam in all supply pipes and condensate in all return pipes.

The pressure loss calculation is based on an average density giving the integrated pressure loss along the pipe.

The pipe outlet temperature on the supply side is based on enthalpy conservation, which means that the downstream enthalpy is equal to the upstream enthalpy minus heat loss and to the environment. The actual downstream temperature is calculated by use of an ASME (American Society of Mechanical Engineers) steam property table using the actual enthalpy and pressure conditions.

The Steam module includes modelling of steam traps. These are devices designed to drain condensate, but steam is also included. The trapped condensate/steam may either be drained to the atmosphere or to the return pipe via an orifice. Furthermore, it is possible to model leaking of steam from the traps.
