If the fluid merely enters the fluid receiving and retaining chamber 50 and is not specifically directed along a defined cooling path, the fluid would generally just randomly migrate around in the fluid receiving and retaining chamber 50.

  • the amount of heat that can be removed from the burner 20 is controlled by the overall size of the cooling jacket, heat transfer apparatus and heat recovery apparatus 30 of the present invention, both the diameter and the length, and also by the amount of coolant fluid that is passed through the burner 20 per unit time.
  • FIG. 23 shows the second preferred embodiment of a cooling jacket, heat transfer apparatus and heat recovery apparatus, as indicated by the general reference 130 for use with a burner 120 that bums a combustible gas such as propane, butane, and so on.
