Heat emission from a burning cigarette was measured. Both radiation heat and convective heat were evaluated individually. Heat flux from a burning cigarette to an object under the cigarette was estimated. Downward and upward heat emissions from a burning cigarette were measured with heat flux sensors. Both downward and upward heat emission were proportional to static burning rate (SBR) of the cigarette. The downward heat emission was about 30% of the total heat emission and can be considered to be half of the total radiation heat. The convective heat was determined by subtracting the downward heat emission from the upward heat emission. The ratio of the convection heat to the radiation heat was independent of the cigarette SBR. Heat flux distribution from a burning cigarette was evaluated by the surface temperature of the cigarette. The heat flux distribution depended on the cigarette SBR, however, the maximum value of heat flux was independent of the SBR.
