Abstract

A turbulent flow field has a major effect on the premixed flame structure and temperature distribution that specifically determines the effectiveness of the burned fuel and the amounts of produced emissions. However, the premixed flame tangential and axial velocity distribution through the flame length help to predict the combustion and emissions attributes of the burned fuel. In this regard, an experimental and analytical investigation on premixed turbulent burners at different equivalence fuel-air ratios with different swirl vane angles has been achieved in the present work to assess the combustion performance and emissions characteristics. A theoretical methodology was carried out to predict the flame temperature distribution with flame length at the equivalence fuel-air ratio of 0.6 and 0.8and swirl vane angle 20^°. Also, the emission characteristics such as NOx, CO2, CO, and UHC have accounted experimentally and analytically to accounting gas temperature, and axial and tangential velocities distribution along the flame length. However, a statistical analysis was performed to verify and validate the proposed model. The prediction and experimental observations illustrated the acceptable agreement whereas the overall error in the experimental testes verification is about 3.66 %.
