Steam Plant Simulation Software

This software simulates a single burner, fuel gas fired boiler for training boiler plant operators, and instrumentation and process control personnel. The boiler can be brought online and fully loaded in a manner that closely follows an actual boiler start up. The simulation includes 3 element / 1 element drum level control, cross limited fuel air ratio control and a burner management system that follows the requirements set down set down in NFPA 8501 Chapter 2 Single Burner Boilers. The boiler is equipped with double block and single vent valves on the main burner and pilot. The dynamics of the boiler can be easily changed to mimic various sizes of boilers. Win Boilers Sim makes extensive use of animation. Steaming, valve position, flame size, drum level, fan and feed-water pump are all animated variables that change with the appropriate process or controller variable.
