Flame Improved by Oxygen-Enhanced

Abstract

This experiment studies combustion gas burner flame by injecting pure oxygen into the oxidizer air stream. The oxygen enrichment can be achieved from 21% up to 21.86% (1 liter/min), 22.71% (2 liter/min), 23.57%, (3 liter/min), 24.42% (4 liter/min) and 25.28% (5 liter/min) respectively. This experiment studies the heat energy, flame shape, emission (CO and CO2) combustion efficiency noise level and flue gas temperature at a certain fuel (LPG) flow rate 0.2 kg/min (200 g/min). The results indicate that the combustion rate, flame shape and temperature increased when the percentage of oxygen were added up. On the other hand, noise emission low level based on air combustion.
