      abstract     = {Pressurized pulverized coal combustion (PPCC) is a novel,
                      coal based combined cycle process which is comparatively
                      simple in design and which offers efficiencies of about 55
                      $\%.$ In order to protect the gas turbine from corrosion and
                      erosion, a gas turbine compatible flue gas has to be
                      supplied. The current specifications of gas turbine
                      manufacturers are particle concentrations below
                      3$^{mg}$/${{m}^{3}_{N}}$ with a maximum particle diameter of
                      3μm and a maximum concentration of alkali species of 0, 01
                      3$^{mg}$/${{m}^{3}_{N}}$. While the demands regarding
                      particle concentration and diameter have been met, the
                      measured alkali concentrations in the flue gas at the test
                      plant in Dorsten are still too high. In order to develop
                      technical measures to reduce the concentration of alkali
                      species in the flue gas, an increased understanding of the
                      release behaviour of alkali species and other pollutants
                      during the combustion of coal is necessary. In this work,
                      the influence of coal composition, temperature and pressure
                      on the release of pollutants during coal combustion was
                      examined. To this aim, combustion experiments were carried
                      out in an atmospheric pressure tube furnace, a high pressure
                      tube furnace and with a flat flame burner. The experiments
                      were supplemented with thermodynamic calculations. High
                      pressure mass spectrometry (HPMS) was used for the
                      semi-quantitative analysis. In this way important insight
                      into the influence of composition, temperature and pressure
                      and into the release mechanisms could be gathered.},
