Description
Summary:Virtually in any industry fuel is burnt in order to convert it to usable energy. The most common way for this is the torch combustion. Previously, it has been demonstrated that implementation of pulsating mode of burning, where the flowrate of fuel fed to the burner is change in a cyclic fashion at frequencies up to 10 Hz, results in considerable reduction of nitrogen oxides in the torch combustion products. The known methods used for processing of data on burning torches obtained by thermal imagers were developed for the stationary combustion mode. This paper describes the development of the data processing method aimed at studies of non-stationary combustion of gas torches in the infrared spectrum, in particular – at pulsating combustion. To run the experiments a special-purpose measuring unit was developed and designed. This unit allows to record burning torch data in the infrared spectrum. This study demonstrates that in the selected band of the infrared spectrum the distribution of pixels does not depend on the mode of combustion, which was repeatedly proven. It was also shown that the abscissa of the minimum on the distribution of pixels by ranges of conditional temperatures (that is, at certain values of the torch brightness) is a stable and quasi-stationary, which makes it available for the use as a control parameter for further processing.
