Due to its very high content of water, mechanically dewatered sewage sludge cannot be incinerated on its own. Peculiar characteristics of dried sewage sludge include its very high proportion of volatile matter and its high contents of the fuel-bound nitrogen and ash. The experimental apparatus consisted of three fundamental partrs: electrically heated reactor, 0.98 m high and of 0.0936-m diameter; facility for the continuous withdrawal and analysis of gas samples, and feeder of solids. Pre-dried sewage sludge particles were injected near the base of a shallow, air-fluidized, bubbling bed of ceramsite under different operating conditions. The study comprised an experimental program of steady-state tests for providing a full picture concerning the influence of main operating variables (i.e., bed temperature, freeboard temperature and excess air) on the most significant gaseous emissions (i.e., CO, NOx, and N2O).

Studie přináší výsledky rozsáhlého experimentálního programu k vyřešení vlivu podmínek spalování vysušeného čistírenského kalu na celkový obraz plynných polutantů.
