The gaseous mixture is then fed through a burner nozzle and burned to heat the atmosphere in a heat exchange chamber. The chamber includes a first coil therethrough in which air from the main oxygen tank is circulated and heated on its way to the diver's mask. A second coil through the heat exchange chamber carries water or other heating fluid from the diver's suit which is heated and returned.
