SimSteam

Steam-System Simulation for Simulink®

SimSteam is intended for use by Process Control Engineers, Mechanical Engineers, Chemical Engineers, Process Engineers and others carrying out engineering design dynamic simulations for steam generation and steam distribution systems; and who are committed to using what is probably the world's most most popular engineering dynamic simulation environment: MATLAB & Simulink, or who are prepared to learn how to use these tools.

SimSteam is a block library for Simulink that enables the dynamic simulation of site-wide steam systems, including such items as Boilers, HRSGs, header pipe work, steam turbines, let-down stations, steam valves and other generators and users of steam. SimSteam also includes a complete version of WATSTEAM (Water & Steam, Thermophysical Properties for MATLAB).

Drag, drop and connect block models for pipe sections and pipe nodes to build your steam header dynamic model. Header volumes are calculated automatically from pipe dimensions. Steady-state and run-end pressures, temperatures, flows and their directions can be shown as annotations directly on the block diagrams.

SimSteam was developed in-house for our own use in our steam-system modelling and simulation studies for our clients in the UK and abroad. SimSteam is now available as an add-on to Simulink to allow our customers and clients to build and test their own steam-system simulations.

Typical applications include modelling and dynamic simulation of steam-generating and distribution plant in support of boiler, HRSG and user trip and shutdown simulation studies, steam-load shedding, steam-flow distribution and other studies of dynamically evolving steam generation, distribution and use.

A SimSteam Licence (single-user, perpetual license) for commercial use costs £2500, with electronic documentation and 1-year E-mail and telephone support. (Holders of WATSTEAM Licenses can upgrade to SimSteam at a reduced price of £2000.) Academic/Educational pricing is also available. Licenses for MATLAB/Simulink are available separately from The MathWorks Inc.
