COOLING JACKET, HEAT TRANSFER APPARATUS AND HEAT RECOVERY APPARATUS

摘要

A cooling jacket, heat transfer apparatus and heat recovery apparatus for use with a burner comprises a main body having a front end and a back end and defining a longitudinal axis extending between the front end and the back end. There is at least one air inlet and a mixing chamber. A fuel passageway has a fuel receiving inlet and a fuel emitting outlet for delivering fuel to the mixing chamber. A first air flow channel has an inlet in fluid communication with the at least one air inlet, and an outlet disposed adjacent the fuel emitting outlet, for delivering air to the mixing chamber. The main body defines a fluid receiving and retaining chamber. There is a fluid inlet in the main body to permit the ingress of fluid into the fluid receiving and retaining chamber of the main body, and a fluid outlet in the main body to permit the egress of fluid from the fluid receiving and retaining chamber of the main body. A plurality of fluid directing vanes are disposed in the fluid receiving and retaining chamber of the main body to define a fluid flow path from the fluid inlet to the fluid outlet.
