Abstract:
A cooking medium heating system includes a cooking vessel for holding a cooking medium, at least one heat transfer tube for transferring heat generated by combustion to the cooking medium, and a combustion gas eductor for venting combustion gas exhausted from a combustion gas exhaust opening. Each heat transfer tube includes a bottom wall, a pair of side walls, a top wall, and a combustion gas entry opening and a combustion gas exhaust opening formed therein at opposite ends thereof. The tubes may include at least one heat transfer fin and a combustion gas flow separator dividing the tube into two spaces between the separator and the pair of side walls. The combustion gas eductor includes a flue including a narrower, exhaust gas receiving end disposed adjacent to the combustion gas exhaust opening, a nozzle including a nozzle inlet and a nozzle outlet, and a blower.
