Modeling and Evaluation of a Coal Power Plant

03-05-2016 The results indicate that cofiring 10% of biomass in a coal-based power plant only slightly affects the energy performance of the plant, reducing the net efficiency by 0.3% points. The addition of an amine capture system to both the coal-fired and biomass cofiring plants further reduces the efficiency of the plants by more than 10% points.

The beneficiation of tailing of coal preparation

In this study, the usability of cyclones in the beneficiation of tailings of a coal preparation plant was investigated. For this purpose, separation tests were conducted using spiral concentrator and heavy medium cyclones with the specific weight of medium 1.3–1.8 (g/cm 3 ) on different grading fractions of tailing in an industrial scale (the weight of tail sample was five tons).

Evaluation of the radiological characterization

The transformation and environmental characteristics of natural radionuclides in a coal‐fired power plant were investigated. The coal, bottom ash, fly ash, and soil samples were collected. The activity concentrations of natural radionuclides (226 Ra, 232 Th, and 40 K) were determined by a high‐purity germanium gamma ray spectrometer.
