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.

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

Life Assessments

Knowing the remaining useful operating life of your boiler, HRSG and associated balance-of-plant is a key parameter for effective management of your thermal power plant.

Performance & Efficiency Assessments

Services to help you evaluate how your operating performance has changed since the plant / boiler was commissioning, or to help you check the potential performance impact of planned modifications before they are implemented.

Root Cause of Failure (RCA)

Knowing the fundamental causes leading to failure is essential to mitigate the risk of the failure repeating. Tetra Engineering calls on an interdisciplinary team to assess the failure (or degradation) and determine the root cause.

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.
