ABSTRACT

This paper summarizes potential modern technologies for large scale power
generation based on lignite which should be used in Kosova. A part of the
study was done to review modern power plant technologies currently available
potential technical concepts for large scale power generation on lignite
taking in account their high moisture contents. Reference is also be made
to the importance of low rank coals-lignite in the international scene. The
combination of the high moisture content and high reactivity of low lignite
necessitates their use close to the mine, unless they can be upgraded to valueadded
products with improved transport safety and economics. Their primary
use is therefore power generation or to provide domestic and industrial fuels for
local use, although a number of novel alternative fuel and non-fuel applications
provide value-added potential. Due to the generally low mining cost of these
coals, emphasis was previously placed on developing technologies to minimise
the capital expenditure rather than maximise thermal efficiency in their use.
However, the current concerns over global warming have focussed attention
on developing utilisation technologies to reduce the comparatively high CO2
emissions from burning these coals.

Keywords: new technologies, lignite, moisture, efficiency, environement.
