Abstract
In the present analysis, the flame stabilization and
temperature distribution within a premixed burner
contain porous wall are studied experimentally. The effects
of inner diameter, length, and pore density of the
porous wall, thermal load, equivalence ratio, and the
inlet velocity of the fuel‐air mixture on these are studied.
The fuel used in this study is natural gas and the porous
wall is SiC (silicon carbide) ceramic foam. The experimental
results clearly indicate that the axial temperature
along the porous wall increases when the inner diameter
of the porous wall decreases and its length increases. The
porous wall temperature with an inner diameter of
40 mm, length of 66mm, and pore density of 30 PPI
(pores per inch) has the highest temperature among the
examined states. The results of studying the effect of the
porous wall on flame stability show that the flame stability
limit has a direct relationship with the length and
pore density of porous wall and an inverse relationship
with the inner diameter of the porous wall. Also, it is
found that the porous wall has the highest temperature
causes the maximum flame stability limit.
