The plants that win are those that treat sootblowing as a dynamic, data-driven process. They install the right sensors, deploy predictive models, and train operators to think in terms of cleanliness factors rather than fixed timers.
Modern systems use a network of thermocouples, gas temperature sensors, and differential pressure transmitters to infer the cleanliness of each heat transfer section. The logic is: soot blow
A 1% increase in flue gas exit temperature (due to fouling) typically reduces boiler efficiency by 0.5–1.0%. For a 500 MW coal plant, that can translate to $1–2 million per year in excess fuel costs. The plants that win are those that treat
For decades, sootblowing was purely heuristic: "Blow every 8 hours during load changes, every 12 hours at steady state." This was crude and inefficient. The logic is: A 1% increase in flue
