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.

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

Optimized NDE

Optimized NDE

Risk-based inspection (RBI) is an approach for ranking the priority of inspection and maintenance according to an assessed risk to the component or system integrity. One key aspect of any RBI program is to carefully select the locations for non-destructive examination (NDE) that are most susceptible to damage, according to the component's design and past and project operating mode, while considering the resources and time available during an upcoming inspection. Using multi-disciplinary experience and tools (thermal simulation, life assessment, structural calculations….) Tetra will help you get the most out of your NDE campaigns, by providing pre-outage planning, on-site supervision and post-inspection review.

Grade 91 Low Alloy Steel Concerns for Older CCGTs

Grade 91 is a CSEF (creep strength enhanced ferritic) alloy introduced in the late 20th century for high temperature service in power boilers. ASME BPVC-II develops material properties based on time-to-rupture data after 100,000 hrs, with a safety factor of 3.5.
