Blue Flame Combustion of a Candle under the Earth's Gravity and at Ordinary Temperature and Atmosphere Pressure

Abstract

The efficient combustion of biomass is important for reducing CO₂ emissions and to prevent people from inhaling toxic carbonous substance emitted from biomass burning. To investigate the possibility of burning biomass in a cleaner way under the earth's gravity at ordinary temperature and atmosphere pressure, a candle, that is composed of simple constituents and shows a luminous flame with slight blue at the bottom, was used, as a substitute for biomass. Almost complete blue flame combustion was attained by applying simple obstacles to the original candle flame.
