| Abstract: | Recently a technique for predicting fly ash resistivity from an as-received, ultimate coal analysis and the chemical composition of the coal ash produced by simple laboratory ignition was published. This paper evaluates this technique by comparing predicted resistivity data with laboratory measured values, in situ resistivity data, and precipitator performance information acquired from 12 field test programs. Considering the precision of measurement generally encountered in precipitator technology and the limited amount of certain laboratory data available, the results are encouraging and the evaluation is favorable. |
