Abstract
The objectives of the present article are to report the development of an inward burning premixed cylindrical flame radiant tube and experimental verification of the similarity of the combustion species concentration and temperature fields. Methane and air were mixed with each other at the molecular level in a tee and in a long tube before entering the burner. Major conclusions of the present study are as follows: (1) The novel burner can stabilize steady state cylindrical flames at various radial positions within an annulus. (2) Measurements of concentrations of combusting species at different axial locations show that they are a function of radial distance only. Complete combustion was achieved without fuel leakage within the least count of the present instrument. Present experimental results support the existence of similarity in the flow field predicted by Takeno and Ishizuka. (3) Temperature measurements exhibit a self-similar radial profile for various axial distances. The self-similar temperature profiles and the large gradient in temperature near the outer wall indicate that the present configuration can result in a very high performance radiant tube.
