Abstract: A gas-fired infra-red burner has a dome-shaped wire mesh burner screen bulging out of the plane of the burner opening away from a plenum. This bulge or dome effect allows the screen to undergo controlled thermal expansion without any rippling, waviness or other undesirable deformation of the screen. A metal blocking plate is secured to the center of the screen and blocks the flow of gas therethrough to create a non-radiating zone at the center of the burner, thus providing even heating over the surface of the food being cooked. A plurality of creases radiate from the approximate center of the plate in a star-shaped pattern, and the plate is bent about several of the creases to give it a concave surface which contacts the screen. When heated, the creases grow in height so that the overall horizontal dimensions of the plate do not increase as much as would a flat plate. The burner venturi tube is of circular cross section adjacent its upstream end and transitions to a flattened, elliptical cross section adjacent the end where it connects to the plenum. The major axis of the elliptical cross section is parallel to the burner opening so that the depth of the plenum, and hence the overall depth of the entire burner unit, may be smaller than if the circular cross section were connected directly to the plenum.

Abstract: A radiant heating system including at least one gas burner and at least one conduit connected to the at least one burner on one end and connected to at least one exhaust tube at an opposite end for transporting hot exhaust gas. Heat is transferred via conduction to an external surface of the conduit. The heat is then radiated omnidirectionaly from the external surface of the conduit as infrared rays. A fan directs a stream of air across the external surface of the conduit to cool the conduit allowing the at least one burner to operate continuously for longer periods of time.

Abstract: An infrared heater for a fluid immersion apparatus such as a commercial deep fat fryer includes a burner whose burner element is made from woven ceramic fibers, preferably formed as a cloth. The burner can also include a wire mesh or screen for supporting the cloth; alternatively, the cloth can be made self-supporting through the wrapping or affixing of several cloth layers together. The burner element possesses a predetermined gas permeability adequate to avoid any significant backflash during the use of the burner. The gas permeability is selected to match the flow rate, composition and backpressure of the selected gas, and takes into account the insulative capacity of the fiber weave employed. The resulting burner construction is substantially more durable and resistant to damage during replacement or inspection than are burners having conventional ceramic elements, such as foams, felts, or the like.

Abstract: A gas burner for use in water heaters, boilers, cooking appliances or the like uses a ceramic cylindrical body to increase conductivity of the gas burner. The gas burner comprises a solid ceramic perforated tube and a flange arranged on one end of the tube. The burner assembly also compromises a cap arranged on the opposite end of the tube from that of the flange, wherein the tube has turn down characteristics of approximately 30 to 1. The tube is manufactured by molding a non-perforated shell within a die assembly. The non-perforated shell is then dried to a predetermined moisture content and machined with a plurality of orifices into the shell to create the burner tube for a ceramic burner assembly.
