Abstract
A steam generator boiler for generating steam is connected to a supply conduit for supplying water to the boiler with a supply valve for controlling the supply of water through the supply conduit. A heater supplies heat to the boiler for generating steam with a discharge conduit for discharging excess impure water therefrom. A metering device is operatively connected to the supply conduit for regulating the flow of water to the boiler by calculating the amount of water required based on wattage or BTU's generated by the heater. A pressure switch or thermostat is provided for operating the boiler and the supply valve on the supply conduit for supplying water to the boiler to permit water to be added every time the heater is energized. In addition, a heat exchanger is provided for receiving discharged heated water from the steam generator and preheating water supplied to the steam generator.
