AI Heat Recovery Systems

Avoids overly conservative, calendar-based part replacement by tailoring maintenance intervals to real operating conditions. Operator distrust of black-box AI and difficulty spotting sensor calibration issues or hidden inefficiencies in complex thermal plant operations.

The Problem

“Optimize heat recovery maintenance and efficiency with explainable AI”

Organizations face these key challenges:

1

Calendar-based maintenance ignores real operating stress and customer-specific usage

2

Operators distrust black-box AI that cannot be validated against thermodynamic logic

3

Sensor calibration drift masks true equipment condition and efficiency losses

4

Complex interactions between load, fouling, ambient conditions, and fluid quality are hard to diagnose manually

5

Hidden inefficiencies persist because alarms are threshold-based rather than context-aware

6

Engineering teams spend excessive time reconciling conflicting sensor readings and maintenance decisions

Impact When Solved

10-25% reduction in premature part replacement spend5-15% extension in component service intervals based on actual duty2-8% improvement in heat recovery efficiency through earlier issue detection20-40% faster diagnosis of sensor drift and thermodynamic anomaliesHigher operator adoption due to explainable recommendations and evidence trails

The Shift

Before AI~85% Manual

Human Does

  • •Review historian trends and operating logs to estimate recoverable heat losses.
  • •Adjust heat recovery setpoints and operating modes based on manual engineering judgment.
  • •Investigate efficiency drops, alarms, and suspected fouling after performance declines appear.
  • •Plan cleaning, inspection, and maintenance using time-based schedules and periodic audits.

Automation

    With AI~75% Automated

    Human Does

    • •Approve operating strategy changes when recommendations affect safety, emissions, or production priorities.
    • •Review prioritized degradation and downtime risks and decide maintenance timing.
    • •Handle exceptions when plant conditions, demand commitments, or equipment constraints require override decisions.

    AI Handles

    • •Continuously monitor process conditions and equipment behavior to estimate recoverable heat in real time.
    • •Detect early signs of fouling, leaks, sensor drift, and performance degradation across recovery assets.
    • •Forecast heat availability and demand and recommend optimal operating points across interacting units.
    • •Prioritize efficiency losses, downtime risks, and corrective actions based on current operating constraints.

    Operating Intelligence

    How AI Heat Recovery Systems runs once it is live

    AI runs the first three steps autonomously.

    Humans own every decision.

    The system gets smarter each cycle.
