Abstract

A thermally sprayed gas heater comprises a gas flow apparatus that propels a gas through a housing; and a thermally sprayed heater bonded to a surface of the apparatus, the heater positioned to heat the gas flow in the housing. In other aspects, a heater system for a turbulent flow gas duct comprises a duct having a gas flow channel, the channel having a shaped surface providing turbulent gas flow in the channel, and a thermally sprayed heater positioned to heat the gas flow in the channel.
