Decrease in nitrogen oxide emissions from the combustion of the prepared gas mixture in the swirl burner
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2017, Vol 21, Issue
Abstract
The results of numerical studies prepared by the combustion of the gas mixture (α'v=0.75) in the vortex burner. The results of computer simulation of three-dimensional low-emission gas burning scheme taking into account the influence of the design parameters of the burners and technological activities. In the calculations made burner design parameters: the register vanes installation angle in the flow of primary air φ1 = 45 ° at α'v = 0.75 and installation angle of the blades in the flow of secondary air φ2 = 60 °, the overall excess air factor is αv = 1.10. Simulation results show that in the methane combustion may reduce the emissions of nitrogen oxides to thermal 25-30 mg/m3 values. Performed numerical study of heat exchange and air dynamics of water-tube steam boilers shows possibility of estimation of operation efficiency of burners
