How many Btu's are given off by one cigarette?

Hmmmm

Is that burning or in the pack?
If burning is it idle in the ash tray or in the process of a big drag?
Standard or virginia slim?

Dave Yates (PAH)

standard

leisurely smoke - not the frenzied suck-on-it-till-there's-a-two-inch-long-glowing-ember you see when truly addicted smokers first get off a long flight!

One cig gives off 1-gram of smoke particulate matter, but I'm curious about the Btu load it adds indoors. Energy costs to filter and condition the air in clubs or restaurants.

Here is a site

that appears to have the info you are looking for. It is all in metrics though so get out the Heating Helper to help convert it. The info you are looking for starts on page 4 of this document.

Alrighty

25 Btu's per smoke,as my rough guess, 500 Btus per pack smoked to the filter. 100 smoking patrons 1 night in the club 1 pack per smoking patron equals 50,000 Btus per night......Priceless. Using Btu content of coal as my base since no Btu content exists for tobacco. Cigarette is about 1 gm of tobacco. 12500 Btu's per pound of coal, 781.25 Btu's per ounce,27.91 Btu's per gm.

Did you come up with a number?

Dave Yates (PAH)

not yet

but at the temps listed (as Glenn said, they begin on page 4), I'd have to think it'd be more like 200+ Btu's per smoke. Unattended, they used to take about ten minutes (evidently most now will extinguish themselves as a "safety feature" - an oxymoron if ever there was one!) to burn down to the filter.

Having once had a lit cigarette in my pants pocket in order to avoid getting suspended from school, I can attest to the fact that they burn through clothing and skin quite effectively!

Based on Aidan's number

I get 14 BTUs per cigarette. A wooden kitchen match is one BTU. bob

Latent heat from filtration system? Extra exhalation in the smoking process?
