Název v původním jazyce

The influence of oxygen-enhanced combustion methods on NOx emissions, in-flame temperatures and heat flux distribution

Popis výsledku v původním jazyce

The present work is aimed at experimental investigation and comparison of characteristics of three various oxygen-enhanced combustion (OEC) methods, namely premix enrichment (PE), air-oxy/fuel combustion (AO) and oxygen lancing (OL). The combustion testsare carried out with an experimental two-staged gas burner at a large-scale burners testing facility. As for the PE method, the high-purity oxygen is injected into the incoming combustion air stream through the diffuser inserted in the air supply duct before entering the burner, while in the AO and OL methods the oxygen is injected directly into the flame through oxygen nozzle heads inserted in the center burner pipe and near secondary gas nozzles, respectively. The total oxygen concentration is variedfrom 21 % to 38 % which corresponds to the flow rate of oxygen in the range from 0 Nm3/h to 100 Nm3/h (N denotes the normal conditions, i.e. 0 Celsius degrees, 101.325 kPa). All tests are carried out at the burner thermal input of 750 kW
