Operational Thermodynamics Methodology
Historian-derived deterministic interpretation of thermal-state behaviour across industrial thermal environments. The institutional methodology framework behind ControlAlign™.
The interpretive framework
Eight engineering disciplines that, together, constitute the operational thermodynamics methodology. Each is independently reviewable, deterministic, and historian-derived.
Steam-Fuel Interpretation
Load-normalized reconstruction of steam-to-fuel behaviour from historian streams, isolating thermodynamic drift from operational variability.
Thermal-State Reconstruction
Reconstruction of the unit's operating state — pressure, temperature, flow, combustion — into a coherent thermodynamic frame for interpretation.
Radiative Coupling Behaviour
Interpretation of furnace radiative transfer behaviour and its contribution to effective heat-transfer under varying load and fuel conditions.
Thermal Coupling Effectiveness (TCE)
A deterministic indicator of how effectively combustion energy is transferred into the working fluid across the operating envelope.
Operational Drift Detection
Continuous identification of deviation from best demonstrated performance, isolated from load, ambient and fuel-quality effects.
Best Demonstrated Performance
Empirical, historian-derived envelope of the unit's own demonstrated optimum — used as the deterministic reference state.
Historian-Derived Interpretation
All interpretation is derived from existing industrial historian environments — read-only, non-intrusive, and operationally unobtrusive.
Deterministic Operational Analytics
No black-box models. Interpretation is reproducible, traceable, and engineering-reviewable across audit cycles.
From historian to audit
A repeatable, deployable systems architecture for operational thermodynamics intelligence. Read-only ingestion, deterministic interpretation, fleet-scale visibility.
Industrial Historian
PI / OSIsoft, Aveva, GE Proficy and equivalent process historians.
Signal Ingestion
Read-only extraction of tag streams; no DCS or control-system authority.
Data Normalization
Load, ambient and fuel normalization to a stable thermodynamic basis.
Deterministic Interpretation Engine
Reproducible thermodynamic interpretation — no opaque ML, no inference layer.
Thermal-State Reconstruction
Coherent reconstruction of the operating state across the load envelope.
Operational Guidance Layer
Drift indicators and operating-envelope guidance for control-room engineering.
Fleet Intelligence Environment
Cross-unit visibility — drift, TCE and best-demonstrated benchmarking at fleet scale.
Audit & Reporting
Audit-grade outputs, traceable to historian source data and reference state.
Trust architecture
Operational governance is part of the methodology — not an afterthought. Eight non-negotiable boundaries that define how ControlAlign™ operates inside utility-grade environments.
Read-only historian ingestion
Operates entirely from a read-only feed of the existing process historian.
No DCS control authority
ControlAlign™ does not write to any control system, actuator or safety layer.
Deterministic interpretation
Reproducible thermodynamic interpretation — no opaque models, no hidden inference.
Audit-grade outputs
Every interpretation is traceable to the source historian tags and reference state.
Traceable operational analysis
Versioned reference states and methodology revisions for engineering review.
Load-normalized interpretation
Load, ambient and fuel-quality normalization isolates thermodynamic behaviour.
Secure processing environment
Isolated processing with strict access controls and no DCS connectivity.
Fleet-scale deployment capability
Designed for multi-unit, multi-site operational deployment across thermal fleets.
