Combustion characteristics of coaxial diffusion flame with preheated air temperature and dilution level
예열공기온도와 희석비율에 따른 동축 확산 화염의 연소 특성
Abstract
An experiment using preheated air in the coaxial diffusion flame burner was carried out in order to decrease NOx emission and improve the thermal efficiency. Preheated air combustion generally produces high NOx emissions but it was known very well to reduce NOx emission by diluting the combustion air with inert gas in preheated air combustion. In our study,
