Standard ISO 19700 proposed equivalence ratio (
) concept, core is to control the generation speed (v of fuel
fuel) with the delivery rate (v of air
air) ratio, shown in formula specific as follows,
When
when=1, >1, represent that respectively material is in air abundance, stable state combustion when stoichiometric ratio (theoretical value) and under oxygen deprivation condition.Wherein,
physical meaning refer to the supply of air when each element in fuel fully burns.Therefore, based on oxygen consumption principle, utilize controlled equivalence ratio method just can Measurement accuracy tobacco heating power under simulation cigarette burning situation.
