Smoker Fuel and the Inspection Clock: A Fuel Sizing Rule in Grams per Hive and the Pace at Which Smoke Demand Outruns the Chamber

The smoker is the beekeeper's clock as much as the beekeeper's tool: when it goes out, the inspection round stumbles, and when it burns fast, the round is punctuated by refills that cost more time than the fuel itself. This paper computes smoker fuel demand from stated-assumption burn rates, bulk densities, a standard chamber volume and a fixed per-hive handling sequence. For wood pellets the fuel sizing rule is 15.6 grams per hive, and one chamber load serves 35.77 hives; for pine needles the rule is 28.8 grams per hive, and one load serves only 2.81 hives. A round of 24 hives takes 4.8 hours on pellets with no refill, against 5.2 hours on pine needles with repeated refills, and two common fuels, pine needles and dried grass, cannot keep a chamber alight for a full hour at any inspection pace because smouldering alone empties the chamber sooner. This study is simulated, not measured; all burn rates, densities and behavioural time constants are stated assumptions, and the outputs are the arithmetic consequences of those assumptions.
