    Abstract: A steam generator to convert liquid into vapor having an inlet to receive liquid, a heating element, and an outlet to discharge vapor. The steam generator may further have a plurality of pathways to facilitate the flow of liquid or vapor through the steam generator. In one embodiment, one or more filter elements disposed in a chamber of the steam generator may help with preventing the buildup of precipitated particulates in the steam generator. In an embodiment, an exit conduit may be configured to further help with preventing particle buildup in the steam generator. In some embodiments, a body may have an inner and outer body and multiple chambers through which liquid or vapor passes as liquid or vapor travels through the steam generator.
