Abstract: Featured is a resistance heater air heating device that includes a low thermal conductivity enclosure and an electric resistance heater that is disposed within such an enclosure. In more particular embodiments, such an enclosure is configured so as to provide a high surface area which in combination with the heater heats the air passing through the enclosure. In more particular embodiments, the ceramic enclosure is configured and arranged so as to include a through aperture in which is disposed the electric resistance heater and through which the air flows along the length of the through aperture.

Abstract: Resistive igniter systems are provided that comprise a metal substrate with an associated resistive igniter element in electrical connection through braze applied to the metal substrate. Igniter systems of the invention can enable significantly simplified manufacturing as well as notably higher yield production of more robust igniters. In preferred systems, the braze material is applied to the metal substrate prior to adjoining the igniter and metal substrate, which can enable application of a relatively precise amount of braze in a defined area of the metal substrate.
