Cofiring and biomass firing have become programs in coal-fired power plants towards net zero emissions. Cofiring with biomass and other solid waste fuel in a coal-fired power plant will undoubtedly impact the power plant's performance. This study evaluates machine learning algorithms for modeling thermal efficiency in a coal-fired power plant. The model …

One of the rapid methods for ash content determination is XRF analysis where the mineral component amount is determined as a sum of all concentrations of oxides [14], [15], [16].The elements in coal are diverse and complex, so the dimension of the dataset is also high [17].Direct fitting may make it difficult to single out and accurately …

The direct gas content determination methods subdivide the total gas content of a coal sample into three components [12].These components are defined as lost (Q 1), desorbed (Q 2) and residual (Q 3) gas.The Q 1 is gas lost from the samples subsequent to its removal from its in-situ position and prior to its containment in the canister. Q 2 is the …

GCV is coal's most influential rank property and depends on the composition of minerals and maceral [6]. The most exact measurement is GCV generated from a coal sample in a laboratory using an adiabatic bomb calorimeter, but the process is expensive, time-consuming, and tedious [4, 7]. These limitations forced the formulation of different ...
