Результаты измерений выхода токсичных веществ и сажи при горении неоднородных керосино-воздушных смесей в лабораторных условиях

Abstract

This paper present measurements results of kerosene-air mixture (kerosene TS-1) heterogeneity influence to the output of toxic substances CO, HC, NOx and soot (PTS.). Heterogeneity inlet chamber has been created by a combination of two homogeneous flows kerosene-air mixtures of varying composition (α1 and α2) with the same velocity and temperature. The degree of heterogeneity of kerosene-air mixture entering the combustion chamber is varied from N = 0 (homogeneous mixture) to N = 1 (the maximum possible heterogeneity). Prechamber square section of 50 mm side is divided by a vertical partition into two equal portions, forming two parallel channels equal in front of the camera. In each channel at the same distance (100 caliber) from the entrance to the chamber has been set at a centrifugal atomizer with the same flow rate characteristics. For each channel, at the entrance to the combustion chamber, there are a mixture of vaporized kerosene and air of different composition. Measurements have been performed on a model of square ramjet combustor type (50 x 50 mm). Flame stabilization has been carried out by two recesses arranged symmetrically in the upper and lower walls of the combustion chamber. Set of refrigerated spacers allow measurements over the entire length of the flame and beyond. Has been carried out measurements for toxic substances in the square ram type model of combustion chamber (50 x 50 mm). Flame stabilization has been carried out by two recesses arranged symmetrically in the upper and lower walls of the combustion chamber. Set of refrigerated spacers allow measurements over the entire length of the flame and beyond. Grounded on samples that has been gained during combustion has been defined the length of the chamber, the length of the combustion zone, assumed that all combustion zones are within the chamber.
