Abstract
All activities in a technically developed society are accompanied by waste
generation. The question of its removal or consequent environment friendly and
economic use has been dealt with by mankind since the early 1990s. The target
of a common international project worked on by the Investex Group, .a.s.
companies and the Research Institute for Brown Coal, the joint-stock company,
is to look for ways to use the sludge from waste water treatment plants as an
alternative resource for additive agent fabrication. Suitable waste treatment
sludge for the additive agent preparation applied in the combustion of lower
quality fossil fuels with a higher content of sulphur is generated as waste in
ammonia fabrication from the sludge produced by municipal waste water
treatment plants. The procedure in the agent fabrication from waste treatment
sludge, the course of the combustion tests and the results of a theoretical level of
desulphurization form the content of this paper.
Keywords: water treatment plant, lignite, desulphurization limestone.
1 Introduction
One of the important sources of energy in the Czech Republic is still the burning
of coal. In order to reduce pollution, it is necessary to reduce the amount of
harmful substances from burning coal, in different ways. Large energy sources,
such as power plants, use combustion gas cleaning. One of the main harmful
substances that is being removed is sulphur dioxide. Its concentration in
combustion gas is directly proportional to the sulphur content in the coal being
burned. During the burning of coal in fluid boilers, a desulphurization additive is
added to the fluid bed – mostly limestone or dry hydrate which causes part of the
