38996Re: FIELD REPORT: Brasslite Turbo I (Steve)
- Oct 5, 2003I've found that if I close the ports about 1/2-3/4 way during
initial firing, the boil time increases significantly, but less fuel
is used. How much less, I'm not exactly sure. There's a trade-off in
allowing the pot to heat more slowly due to ambient heat loss to the
air, which may be modified by playing with the windscreen. I haven't
been able to consistently get any of my stoves to use less than 12
ml. of alcohol to boil 16oz. of water, even under "ideal"
conditions. 12 ml. seems to be the lower limit. There are so many
other external factors besides fuel(air temp, water temp, elevation,
wind, pot size/material, and position of windscreen) that whatever
results I might obtain would not easily be duplicated by others in
the field. Most people seem to be able to get a boil of 16 oz. of
water using 15 ml(0.5 oz) of alcohol. However, in BGT (and other)
field tests I've sometimes heard an ounce wasn't enough if the wind
was blowing. There are steps that can be taken to improve the
environment around the pot (ie. foam pad wind break) to bring the
fuel usage back in line with average. In other words, fuel economy
is also mitigated by the experience level of the user.
