Abstract
In recent years, the focus for the development of combustion technology focus
has been set on the following main aims: fuel consumption reduction, nitrogen
oxides emission reduction, increased productivity and product quality. Fuel
consumption reduction has been reduced by as much as 30–40%, and also CO2
emission reduction was achieved by replacing combustion air with oxygen. To
achieve very low emission of nitrogen oxides (NOx) the new combustion
technology is characterised by: lower temperature of flame, more uniform
temperature distribution and reduced concentration of oxygen as well as nitrogen
inside the combustion chamber. As in this combustion technique a flame is
replaced by a large chemical reaction zone and thus is often not visible the
process was named as \“flameless” combustion. \“Flameless” combustion process
that use oxygen, so called oxyfuel combustion, as well as its technical
application is the subject of this work. The work presents a description and main
features of the \“flameless” oxyfuel combustion, results of laboratory tests of a
new type of burner, REBOX®, as well as examples of industrial applications
including waste incineration are included.
