Boiler Efficiency Optimization
Autonomous Loss Reduction & Fuel Savings
Increase boiler efficiency from ~80% to 83-85%, reduce fuel consumption, and detect operational inefficiencies in real time using AI analytics on existing combustion and process data. No new sensors required.

AI-ranked root causes of efficiency loss with explanation and recommended action
O₂ levels swing between 2.1% and 4.6% across load ranges. At 70-80% load, median O₂ reaches 4.45% vs. an expected 2.8%. High O₂ means excess air is absorbing heat and carrying it out the stack. This is direct fuel waste.
Recalibrate the air/fuel ratio control valve. Adjust damper positions for the 60-80% load range. Target O₂ between 2.5-3.5% across all loads.
Stack temperatures range from 130°C to 180°C with wide spread across operating conditions. High stack temperature means thermal energy is escaping to the atmosphere instead of being transferred to water/steam.
Inspect and clean heat exchanger surfaces for fouling. Evaluate economizer performance. A 20°C reduction in stack temperature can yield approximately 1% efficiency gain.
Efficiency stays flat at ~79.5-80.5% regardless of load (20-100%). Typically, boilers should operate more efficiently at higher loads. A flat curve indicates the combustion control logic is not adapting to changing conditions.
Review and retune the burner modulation curve. Implement load-dependent air/fuel ratio setpoints. Consider upgrading to O₂ trim control if not already in use.
Load distribution shows a heavy spike near 100%. Running consistently at maximum load increases thermal stress, accelerates wear on refractory and tubes, and reduces the window for efficiency optimization.
Evaluate if load can be distributed across multiple boilers. Consider staging strategies to keep individual units in their optimal efficiency band (typically 60-85% load).
