Electric thermal storage heater system for heating fluids

A thermal storage heater system comprising:

• means for storing a high temperature fluid, including means for heating the stored fluid to a high temperature, thereby storing heat in the fluid;
• first heat exchange means for heating a fluid to be heated mounted in said storing means in heat exchange relationship with the high temperature fluid stored therein, said first heat exchange means including at least one tube with an inlet and an outlet aligned in a horizontal plane, and
• a first fluid circuit in fluid communication with the inlet of said first heat exchange means and a source of a first fluid to be heated coupled to said first fluid circuit, a heating coil in said storing means in heat exchange relationship with the high temperature fluid therein, a second fluid circuit in fluid communication with the inlet of said heating coil for circulating a second fluid to be heated therein, and a condenser in communication with said second fluid circuit, said condenser comprises a spray tube communicating at a first end with said source of second fluid and at a second end with the inlet of said heating coil, an outer shell concentric of said spray tube and an imperforate baffle interposed between said tube and said shell, said shell communicating at one end with the outlet of said heating coil, and at its other end with said second fluid circuit.

In a thermal storage heater system for heating fluid including means for storing a liquid capable of being heated to a high temperature, means for heating the stored liquid to a high temperature, heat exchange means in said storing means for transfering heat from the high temperature liquid to a fluid to be heated, fluid circuit means for communicating said heat exchange means with a source of fluid to be heated and a fluid utilization device coupled to said fluid circuit means, the improvement comprising;

• a condenser in said fluid circuit means, said condenser condensing steam from said heated fluid on exiting said heat exchange means and comprising an outer shell for containing heated circuit fluid flowing from said heat exchange means to said utilization device, an inner spray tube mounted in said shell for distributing fluid from said source of fluid, internally of said shell and to said heat exchange means, and a baffle mounted in said shell between said shell and said tube, wherein steam generated by said heated fluid on entering said shell is condensed by said source fluid to be heated, providing continuous flow to said utilization device.
