Emissions of Toxic Components from Firing of Used Oils in a 102 kW Burner Boiler
Tydlitát, Vratislav ; Janota, J. ; Pekárek, Vladimír ; Punčochář, Miroslav
Firing of used motor oils in burner-type boilers does not produce emissions of the investigated substances which would exceed the current emission limits, except for a small deviation in the content of chlorine. The measurements unexpectedly showed that the new limit for PCDD/F to be effected in the Czech Republic since April 2002 is only slightly exceeded.
Pop Formation at Co-combustion of Wastes and Coal
Veselý, Václav ; Punčochář, Miroslav ; Čech, B.
Co-combustion of PVC and coal produced from 8 to 25 ngTEQ/m3. Formation of p-dioxine is eliminated by addition SO2/SO3. The main influence on concentration PCDD is equilibrium SO2 ů SO3 and HCl ů Cl2. Formation of dibenzofuranes is independed on concentration SO2/SO3.
Recyklace paladia z polymetalických roztoků vznikajících loužením elektrochemického šrotu
Gruber, Václav ; Punčochář, Miroslav
In the present work, the rate of the reduction of divalent palladium with formaldehyde was determined in several inorganic solutions. The effect of temperature and Pd2+ concentration on the reaction rate is discussed, a simple kinetic model of the process is proposed and tested, and its parameters are calculated for specific conditions.
