Kohlenstaub-Druckverbrennung : Entwicklungsstand und Anforderungen des Prozesses an die Verbrennungsführung

Pressurized pulverized coal firing develops power station process efficiencies in the region of 50%. In this process, the hot flue gas is introduced directly to a gas turbine. Special requirements are imposed thereby on fluid ash deposition and on minimization of alkali concentrations. High NO x concentrations occur at high combustion temperatures according to the process used. By means of mathematical models. measures to reduce NO x can be studied and evaluated.
