Pollutant emission and noise radiation from open and impinging inverse diffusion flames

This paper reports an experimental investigation of the pollutant emission and noise radiation characteristics of both open and impinging inverse diffusion flames (IDFs), produced by five burners of different air port diameter (dair=5, 6 and 6.84mm) and air-to-fuel spacing (S=8, 11.5 and 15mm). The effects of dair, S, overall equivalence ratio Ф and nozzle-to-plate spacing H on the pollutant emissions of CO and NOx and the noise radiation are examined.
