ABSTRACT:
Steam is produced by introducing compressed air into one end of a vessel, heating the air, and inducing a continuous swirling motion of the air as it travels from an inlet toward an outlet. A heated deflector plate is disposed in the vessel upstream of the outlet and is opened at its outer periphery to conduct the swirling air. Water is sprayed against a backside of the heated deflector plate such that the water becomes vaporized and entrained in the air flow to exit as steam through the outlet. Additionally or alternatively, a pair of outlets can be provided, one situated at a radially outer portion of the vessel and another situated centrally of the vessel. Hotter steam is exited through the outer outlet and cooler steam is exited through the center outlet.
