PHOTOMETRIC PROCEDURE FOR THE DETERMINATION OF THE CALORIFY POWER OF A TEST GAS.

摘要

Procedure for the photometric determination of the calorific value of a test gas, in which a broadband measuring radiation drives the test gas that has CH-bonds and spectrally decomposes the measuring radiation that passes through the test gas and drives a radiation receiver, with which, according to the intensity of the measurement radiation that drives it at different wavelength ranges, electrical measurement signals are generated, which are amplified with a predetermined degree of amplification, which is characterized by a parameter of the calorific value (bi) associated with the wavelength range, and are added, the calorific value of the test gas being determined from the summed measurement signals, characterized in that the intensity of the measurement radiation is detected at intervals of wavelengths, which detect the spectral region, in which the oscillation or oscillation are found Harmonic lamination of the C-H bonds, where the number of wavelength intervals depends on the spectral widths and average wavelengths, to detect the intensity of the measurement radiation in the spectral range.
