A natural draft combustion system having a housing enclosing at least a portion of a material heating container and at least one combustion space in heat exchange relation with the material heating container and extending from a heat inlet side of the housing to a heat outlet side of the housing. A downward angled burner having a burner outlet in fluid communication with a heat inlet to the at least one combustion space is disposed on the heat inlet side. A natural draft combustion products exhaust conduit in fluid communication with the at least one combustion space is disposed proximate the heat outlet of the housing. As a result, a flame produced by the burner is introduced into the combustion space with a downward velocity component, which, in turn, results in improved efficiency over comparable conventional systems.
A natural draft combustion system comprising:
In a hot oil fryer comprising a housing enclosing at least a portion of a liquid container and at least one combustion space in heat exchange relation with said liquid container having a heat input side forming a heat inlet and an opposed heat output side forming a combustion products exhaust, a burner disposed on said heat input side having a burner outlet in fluid communication with said heat inlet, the improvement comprising:
In a heating apparatus comprising a housing enclosing at least a portion of a fluid container, at least one combustion space extending from a heat inlet side to an opposed heat outlet side and having a heat inlet, said at least one combustion space being in heat exchange relation with said fluid container, and a burner having a burner outlet in fluid communication with said heat inlet, a method for heating a fluid in said fluid container comprising:
