The paper presents a method for determining thermo-flow parameters for steam boilers. This method allows one to perform the calculations of the boiler furnace chamber and heat flow rates absorbed by superheater stages. These parameters are important for monitoring the performance of the power unit. Knowledge of these parameters makes it possible to determine the degree of furnace chamber slagging. The calculation can be performed in online mode and used in the monitoring of the steam boiler. The presented method allows the steam boiler to be run at high efficiency.
