Bunsen’s studies of the composition of gases given off from blast furnaces showed that 50 to 80 percent or more of the heat was wasted and led to elaboration of his methods of measuring volumes of gases in his only publication, Gasometrische Methoden (1857). Bunsen burner, device for combining a flammable gas with controlled amounts of air before ignition; it produces a hotter flame than would be possible using the ambient air and gas alone. However, unless the airflow is adjusted as well, the flame temperature will decrease because an increased amount of gas is now mixed with the same amount of air, starving the flame of oxygen. The Bunsen/Desaga design succeeded in generating a hot, sootless, non-luminous flame by mixing the gas with air in a controlled fashion before combustion.
