“…In literature, you can find positions on the methodology of calculating fouling and slagging factors. The calculations are based on the use of the heat transfer model in the boiler and the determination of the thermal power absorbed by the heating surfaces [6][7][8]. Taler and others [6] applied a model of heat exchange in the furnace chamber to assess the evaporator cleanliness.…”

The article deals with the problem of optimizing the operation of soot blowers in a pulverized coal-fired boiler based on the instantaneous degree of cleanliness of heating surfaces, determined in real time. The elaborated methodology of calculations and the algorithm that determines the optimal configuration of the blowers operation has been implemented and tested on a boiler with a capacity of 380 t/h. The indicator defining the degree of cleanliness of a given heating surface is calculated using available measurements of process parameters based on the epsilon-NTU method. The calculations are carried out in the DCS system for each surface individually (air and water heaters, evaporator, superheaters). During the standard operation of the boiler, the adopted methodology was verified, having analysed the usefulness of the tool to assess the boiler cleanliness under operating condition.
