Process optimization of sampling and determining the uncertainty associated with the properties of solid fuels for cocombustion

Abstract

This paper presents the process used to determine the statistical uncertainty associated with eight different properties of solid fuels for co-combustion tests of moisture and ash. Provides a map of sampling to determine the sample sizes in the light of the uncertainties that are considered acceptable. The values obtained show that despite the heterogeneity of the fuel itself, a well-planned campaign of samples can extrapolate the properties of the samples from the entire lot with an uncertainty controlled and quantified.
