Abstract
An apparatus and method are provided for determining the heat of combustion of a material. The apparatus comprises a burner capable of producing a diffusional flame; a device for conveying a sample of the material to the burner, so that the sample is burned within the diffusional flame; and a mechanism for determining the height of the flame in the burner. The method of the invention comprises forming a diffusional flame; burning a sample of the material within the diffusional flame; determining the height of the diffusional flame which results as the sample is burned; and comparing the height determined when the sample was burned with heights determined when standards were burned, the standards having known values for their heats of combustion.
