ABSTRACT:
A spectrophotometric method is disclosed for measuring the heating value of a mixture of substances commonly comprising a gaseous fuel. The method is based on the recognition that within certain wavebands the mixture exhibits a correlation between heating value and the strength of radiant energy absorption. A spectrophotometric apparatus is disclosed which is adapted to permit the continuous observation of the heating value of the mixture.
