Analysis of technical parameters of black coals used in low–power boilers

The article presents the results of technical analysis of black coals available in retail sales in Poland. A comprehensive list of fuel technical parameters and analysis of the possibilities of their use in low-power boilers was supported by the experience of the authors of the study. A thorough analysis of technical parameters of fuels concerned basic thermodynamic parameters of fuels responsible for the quality of thermal processes occurring in boilers. The collected data is presented in a uniform description of the current state of the sold fuels. In the last point, the researchers were looking at the technical aspects of the fuels offered in relation to the existing emission standard for low-power boilers.
