Boiler Process Modelling and Simulation

Tetra Engineering provides a full-scope service for the modelling and operation analysis of all types of natural or forced circulation Power Boiler and HRSGs, including supercritical and once-through designs.  This can be integrated into a full plant model to incorporate the steam turbine and steam cycle balance of plant.

The level of detail can be adapted to focus on local effects (e.g. row-to-row temperature differences) and can be steady-state or time-dependent, the latter to model transients such as startups.  The state-of-the-art Power Plant Simulator and Designer™ (PPSD) software package developed by KED software is the primary tool for this work.  Frequent applications at Tetra Engineering include:

  • Calculating steam cycle efficiency (heat balance) according to ASME PTC or other codes
  • Determining natural circulation rates in support of FAC risk assessment
  • Generating metal temperature profiles for inputs to finite-element stress calculation
  • Assessing the impact of design changes or modification to original plant operating regime
