Abstract
In this study, the effect of steam addition on spray combustion characteristics was investigated experimentally. A small scale experimental spray combustor which had a swirl burner was used. Kerosene was used as the fuel. The steam flow rate was changed in the steam addition cases. Two steam addition methods (CASE 1 and CASE 2) were used. In CASE 1, the steam was directly introduced into the fuel spray. In CASE 2, the steam was mixed with air and introduced into the combustor together. The temperature, O2, CO, CO2, and NO distributions in the combustor were measured. As a result, the miximum temperature and the high temperature region in the combustion chamber were decreased by steam addition, and therefore thermal NO was effectively reduced. The effect of NO reduction in CASE 1 was larger than that in CASE 2. However, in CASE 2, more steam can be added than in CASE 1 with CO emission kept low.
