Re: Nitrous oxide and virgin introduction... just curious.
There are at least three gases that are formed when ammonium nitrate burns: NO2 (nitrogen dioxide), NO (nitrogen oxide) and N2O (nitrous oxide). The last is 'laughing gas.' Since the first two are somewhat corrosive, I suspect that the purpose of burning ammonium nitrate is to make nitrous oxide. The amounts of these gases that are formed depend on the precise conditions (temperature, oxygen amount, moisture) inside the smoker, so it's not possible to nail down the exact amount of nitrous that would be produced from a fixed amount of ammonium nitrate. Hotter, more moisture and more oxygen would lead to higher amounts of the first two gases. But, they will always be there no matter what the conditions. chucking reality aside, and assuming that only nitrous oxide is formed, if one teaspoon of ammonium nitrate has a mass of 10 g, then:
10 g (1 tsp) ammonium nitrate produces up to 10.4 g (11 L) of pure nitrous oxide. A canister contains about 8 grams of the same gas, the same as 8.5 L once opened up and no longer under pressure.
If it is nitrous oxide that does the trick, then the canisters would be a safer way to deliver it (no corrosives).
