Evaluation of the influence of the soot deposition on thermocouple measures in combustion experiment

Abstract

Soot formation in industrial combustion systems constitutes an important theme of the engineering interest. The presence of the soot in the flame increases the transfer of the heat from the combustion gases by thermal radiation, yet it may constitute an environmental problem when is emitted in the atmosphere. This work evaluates the influence of the soot deposition in the thermocouple’s measures in an acetylene diffusion flame, produced in a burner with parallel coaxial oxidizer flow that has problems of accurating the temperatures measures with thermocouple. The evaluation about the date explains the influence of the soot deposition in the measures of temperatures and how these errors influence the analysis of physical phenomenon.
