Apparatus and method to distinguish between oil and gas combustion by remote observation using an infrared spectrometer

摘要

An apparatus and method for detecting and analyzing the emissions or effluents from gas or oil combustion so as to discriminate between them. A spectrometer detects the spectra of a combustion effluent or exhaust. Identifying features of carbon dioxide and water vapor are selected at predetermined wavenumbers. The ratio of the relative intensities of the identifying features of carbon dioxide and water vapor is then computed, which results in the discrimination between oil and gas effluents.
