Abstract This paper reports an experimental work related to measurement of
laminar flame speeds of liquefied petroleum gas (LPG) (Indian domestic grade)
against calibrated LPG fuel (70% propane + 30% n-butane). The measurements
were carried out on in-house developed cylindrical flame tube apparatus. The flame
speed was calculated by measuring the distance propagated by flame front of a known
test length on flame tube. The reported work also brings out the partial automation
feature that was added to the existing flame tube apparatus, which lead to determination of flame speed electronically. The average flame speed of respective gaseous
fuels was measured on manual basis (using stop watch) and also through photocells
(LDR sensors). The error in measurements was found to be well within 2% and quite
satisfactory. The experimentally obtained values were compared against literature to
address the gap.

1 Introduction
In the recent times, combustion has played a vital role in driving the humanity toward
the pathway of prosperity and progress, but at the cost of environmental degradation.
About, 80% of the worldwide energy demand is alleviated by combustion of fuels.
