The physics of the boiler island,
resolved at operating granularity.
YBG Global is built on a first-principles understanding of the thermodynamic and heat-transfer processes that govern utility-scale combustion. Radiative coupling between flame and furnace wall, convective heat transfer through the superheater and economiser banks, and the combustion stoichiometry behind them are not modelled inferentially — they are resolved against the plant's own operating record, load band by load band.
This is the work that distinguishes a measurement layer from a dashboard. A dashboard reports what a sensor saw. A measurement layer understands why that reading was physically possible — and what an adjacent operating point would have produced under the same boundary conditions.
The result is a determination an operator's own performance engineer can review line-by-line: not a prediction, not a benchmark, but a quantification of what the unit has already proven it can do.
- Radiative couplingFurnace-wall absorption resolved per load band; flame emissivity and view-factor effects accounted for at native DCS resolution.
- Convective heat transferTube-bank fouling and gas-side film coefficients separated from boundary drift, not lumped into a single heat-rate residual.
- Combustion stoichiometryExcess-air, unburned-carbon, and GCV interactions reconciled against measured fuel and steam flows — no assumed split.
- Load-band normalisationPerformance envelopes constructed per load band; partial-load behaviour not extrapolated from full-load curves.
- Steam-side reconciliationHeat balance closed across drum, superheater, reheater, and economiser using the plant's instrumentation, not synthetic tags.
- Best-observed envelopeP10 of the unit's own operating record — what the asset has demonstrated, not what a fleet average suggests.
