A module system for thermal diagnosis has been developed and put into practice at the BOT Opole Power Plant. The described system includes the following modules: preliminary and advanced validation of measurement data, thermal calculations of the boiler, calculations of indices characterizing the operational conditions and its deviation of the index of specific consumption of fuel chemical energy. The advanced validation of measurement data is based on the criterion of Gauss likelihood function maximization and on the validation model of the steam cycle. The DIN 1942 standard is applied for thermal calculations of a steam boiler. Reconciliated measurements data and unmeasured parameters of power unit operation for calculations of indices characterising the operational conditions have been used. A simulation model of power unit has been worked out. The developed model is applied for calculations of the deviation of the specific consumption of chemical energy of fuel.
