| dc.description.abstract | Burners at coal fired Power Plants require a controlled ratio of air fuel mixture to realise lower NOx emissions and to optimise combustion efficiency in coal fired power plants. Another contributing factor for lower NOx emissions is the coal particle size distribution. Iso-kinetic sampling is utilised for the monitoring of PF size and mass distribution to the burners at Power Utilities. The accuracy of these sampling methods is questionable. The primary aim of the project was to establish the degree of accuracy of the manual and automated sampling equipment used in Eskom and their methods of application. Based on international and local standards and procedures a testing program was setup and the sampling equipment were evaluated on an industrial scale at one of Eskom’s Power Plants. Flow correlation calculations and CFD modelling were also carried out to complement the site evaluation of the PF Sampling methods. The Rotoprobe and 3 Axis traverse produce favourable results with respect to accuracy and repeatability. The target plate and 1 Axis traverse produced questionable results. | |
