Observation: See clearly, repair preciselyObservation
The furnace is the least visible part of a boiler — whether the flame is centered, where slag builds up, which tube section runs hot, was long inferred from instruments alone. High-temperature imaging and temperature-field reconstruction turn it into continuous images and traceable curves: operators spot deviations earlier, and maintenance decides more precisely what to fix first and when. See clearly, repair precisely — and base every judgment on evidence.
