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

Popis výsledku v původním jazyce

The aim of the present study was to experimentally investigate and compare the characteristics of three various oxygen-enhanced combustion (OEC) methods including premix enrichment (further denoted as PE), air-oxy/fuel combustion (further denoted as AO)and oxygen lancing (further denoted as OL). The combustion tests were carried out with the experimental two-gas-staged burner at the large-scale burners testing facility. As for the PE method, the oxygen was injected into the incoming combustion air stream through the diffuser inserted in the air supply duct, while in the AO and OL methods the oxygen was injected directly into the flame through the oxygen nozzle heads placed at different positions depending on used OEC method. The total oxygen concentration in the incoming air was varied from 21 % to 38 %. All combustion tests were carried out at the burner thermal input of 750 kW for two combustion regimes ? one-staged and two-staged fuel combustion. The target oxygen concentration in
