Účinnost odsiřování v sub-stechiometrickém tlakovém spalování uhlí – teoretické a praktické problémy
Svoboda, Karel ; Pohořelý, Michael ; Schosger, J.-P. ; Baxter, D. ; Rogut, J.
This paper deals with a comparison of pressurized thermogravimetric (TG) analyses of desulfurization with Cizkovice limestone under steady state reducing conditions at temperatures 800 and 900 oC and operating pressure 1 MPa with the same limestone under conditions of sub-stoichiometric PFBC of coals at air/fuel ratio = 0.75. Comparison of attainable degree of desulfurization in the PFBC and composition of solid product with theoretical predictions of desulfurization efficiency and with results of TG analyses has shown that desulfurization in sub-stoichiometric PFBC is more complicated involving formation and reduction of CaSO4.
Vývoj a praktické testy izolační a současně chladící skřínky se senzorem pro in-situ měření koncentrací CO na pohyblivých roštech ve spalovnách komunálních odpadů
Martinec, J. ; Skála, Z. ; Schosger, J.-P. ; Baxter, D. ; Svoboda, Karel
In-situ measured data are essential for better understanding and further development of incinerators with moving grate burning solid waste. We have designed and developed a special cube-capsule with insulating refractory ceramic fibres and materials with cooling effects enabling measurements of temperature and CO by an electrochemical sensor, small gas pump and electronics placed inside. This self-contained and mechanically/thermally protected probe consisting of measuring and recording electronic components was able to withstand temperatures over 1000 oC for a period longer than two hours.
