Abstract

To support power plant operators in daily decision-making and in plant operation optimisation, advanced methods for combining data from deposit formation monitoring and process calculations are being developed. These methods will help power plant operators to achieve better power plant performance with improved fuel flexibility. Correlation has been observed between temperature behaviour of VTT Prosesses' deposit monitoring probe and thermal efficiency of steam boilers. Based on the data provided by heat transfer monitoring probes, correlations have been developed to describe on-line changes in heat transfer rate and boiler efficiency. This gives basis for developing on-line methods for maximising boiler efficiency and quantifying the implications of applied fuel blend on boiler performance.
