Original abstract
The present paper describes the influence of important geometry parameters of a gas burner on the formation of nitrogen oxides. Large number of experiments was carried out using a burner with staged gas and air supply and nominal duty of 1000 kW. Natural gas was used as the fuel. The tests were aimed at analyzing the influence of geometry factors, namely size, shape and position of swirl generator, position of secondary nozzle heads, impact of homogenization of combustion air and other parameters on the formation of nitrogen oxides. Formation of nitrogen oxides was not the only observed dependent variable. Other variables included carbon monoxide emissions, as well as the shape and structure of visible flame. The paper deals with the analysis of a gas burner design with staged air or staged gas supply for primary reduction of thermal nitrogen oxides.
Czech abstract
Prezentovaná práce popisuje vliv důležitých geometrických parametrů plynového hořáku na tvorbu oxidů dusíku. Vysoký počet experimentů byl proveden s plynovými hořáky se stupňovitým přívodem plynu a se stupňovitým přívodem vzduchu o nominálním výkonu 1000kW. Jako palivo byl použit zemní plyn. Cílem experimentů bylo posoudit vliv geometrických parametrů hořáků na tvorbu oxidů dusíku, jmenovitě vliv velikosti, tvaru a pozice vířiče, pozice sekundárních trysek, vliv homogenizace spalovacího vzduchu a salších parametrů. V průběhu experimentu nebyla sledována pouze tvorba oxidů dusíku. Dalšími pozorovanými veličinami byly emise oxidu uhelnatého, tvar a struktura viditelného plamene. Práce se zabývá následnou analýzou naměřených dat, která vede k redukci emisí oxidů dusíku.
