The ageing of plant assets presents a real problem for owners and operators. The viability of future operation can be called in to question when a boiler or HRSG begins experiencing failures, reducing availability and the bottom line. The decision to run, re-rate, replace or retire is one that can only be answered by in-depth, cross-discipline analysis. In particular, the gap between engineering and economic questions can be difficult to bridge.
Tetra aims to address both questions by first understanding the degree of degradation to the pressure parts:
- Superheaters and Reheaters
- Evaporators and Waterwalls
- Economisers and Preheaters
