ABSTRACT

Conventional fossil fuels as well as alternative ones are carriers of energy which is
transformed and used during combustion processes in power-generation plants. The
knowledge of precise fuel quality is thus indispensable information as it is related to a
number of further calculations and processes. Both accurate analytical processes as well
as precise representative sample drawing are crucial for an exact determination of
qualitative fuel characteristics. In large power-generating plants, those activities are
carried out using automatic sampling lines, which may however cause a constant shift in
the qualitative values of the drawn samples and they may thus distort further
calculations for which the values are used. The paper also deals with the question what
may cause the shift, it describes the course of its evaluation and finally it states possible
consequences for certain balance calculations in power-engineering.
