Annotation	V práci je navržen a ověřen matematický model pro vysokoteplotní oxidaci toxického oxidu uhelnatého pro režim ideálně míchaného reaktoru. Numerická řešení modelových rovnic vymezují možnosti výkonu dopalovací komory za realistických pracovních podmínek.
Description in English	An ideally mixed flow model is developed for the high-temperature oxidation of toxic carbon monoxide into inert carbon dioxide occurring in an afterburner chamber. The extent of the oxidation reaction in oxygen – and water vapor – bearing flue gas is explored as a function of the relative throughput, the gas density, and the global rate of reaction. Steady-state experimental measurements of the CO, O2, CO2, and water vapor concentrations were conducted in a pilot-plant refractory afterburner fitted with a natural gas burner. The global burnout reaction is assumed to be first order in carbon monoxide and one-half order with respect to oxygen and water vapor. The numerical solutions of the model equations outline the possibilities and limitations for the performance of a well-mixed afterburner chamber (reactor) under realistic operating conditions.
