Answer» Not satisfied with these answer. Kahan se copy kiyA hai.....valise. ..mst....hai..thanks •A blue gas flame indicates complete combustion. Red or yellow gas flames may be the sign of incomplete combustion. With hydrocarbon flames, such as gas, the amount of oxygen supplied with the gas determines the rate of combustion. This is the most important factor in determining the colour of the flame. Blue Flame = Complete Combustion•When you adjust a burner to increase the air supply you get more complete combustion, less soot, a higher temperature and a blue flame. With complete combustion, an LPG (Propane) flame burns at a temperature of around 1,980°C. For Natural Gas (Methane), the temperature is about 1,960°C.Complete Combustion:Gas + Oxygen = Water + Carbon Dioxide + Heat Because flame is only produce when gaseous substance burns |
