<p>An apparatus for generating steam from water in a tank. A heater is located within a member having labyrinthine baffles thereon. The member is located within a bore formed within a housing and is supplied with water from the tank by an electromagnetic pump. The pump may be comprised of an electromagnetic coil in contact with a pivoting armature. The armature is connected to a diaphragm in communication with an inlet valve and an outlet valve. A control means may be provided to limit movement of the armature and thus to control the amount of vapor pumped and steam produced. Water contacting the heated section is vaporized and passes through an outlet in the housing. Preferably, the baffles are comprised of a series of anti-sputter baffles at the top of the heater for preventing condensed water from exiting through the outlet. A condensate trap may be connected to the outlet from preventing condensed water from exiting and for directing condensed water back into contact with the baffles. In such an embodiment, an outlet with a drain valve is provided for redirecting, condensed water into the tank. It is contemplated that baffles may be arcuate with alternating apertures therein.</p> |
