摘要： A UV reactor for treating water, the reactor includes a UV source, a tube positioned around the UV source, a surrounding structure coaxially surrounding the tube, a flow path positioned between the tube and the surrounding structure for the flow of water to be treated, and a diffusive surface positioned around the surrounding structure to reflect UV light from the UV source back into the flow path.

摘要： A flame rod analysis system, methods for determining a condition of a flame and a flame rod, and circuits for determining a condition of a flame and a flame rod. The flame rod analysis system comprises energy storage connectable to a flame rod, a pulsed source connected to the energy storage and providing a voltage pulse or a current pulse, and a buffer to allow a processor to measure a buffered voltage at various time points. Flame rod analysis systems can distinguish between various flame conditions (no flame, low flame, etc.) while simultaneously characterizing the condition of the flame rod (shorted to ground, contaminated, etc.). Some flame rod analysis systems can directly measure the resistance of the flame rod.

摘要： A modulating burner apparatus includes a variable speed blower feeding a multi-chamber burner having first and second burner chambers. A manifold system communicates the blower with the burner, and a flow control valve member is located between the blower and the second chamber of the burner. The flow control valve is configured to provide fuel and air mixture from the blower to only the first burner chamber at lower blower speeds of the blower and to both the first and second burner chambers at higher blower speeds of the blower.

摘要： A water heater includes a tank containing water to be heated and a thermal displacement conduit communicating between a portion of the tank and a receptacle. Water is displaced out of the portion of the tank, through the conduit, and to the receptacle during thermal expansion of the water during heating.

摘要： A burner apparatus for burning a gas and air mixture may include a burner wall. The burner wall may have a plurality of ridges and a plurality of grooves. Each groove may be defined between adjacent ridges. Each groove may also include a pair of slopes. Each slope may have an area of permeability having openings defined therein from which flames can project. Each ridge may define an area of reduced permeability relative to the areas of permeability of the slopes.

摘要： System and methods of operating a water heater receiving power from an electrical grid. The water heater includes a heating element, a controller, and a first control circuit. The first control circuit including an energizing terminal and a microprocessor. The method includes connecting an energizing terminal of the first control circuit between a power output terminal of the controller and the heating element, receiving driving power from the controller based on a temperature signal. The method also includes receiving control signals from the controller based on electrical grid information, and selectively energizing the heating element, by the microprocessor of the first control circuit and through the energizing terminal of the first control circuit based on the control signals.

摘要： A fuel fired, atmospheric water heater has a burner positioned inside a combustion chamber. All combustion air entering the combustion chamber must pass through a damper. The damper is operable to adjust the flow resistance to combustion air entering the combustion chamber. The damper is biased to a closed position such that during non-firing periods of the water heater, the damper significantly reduces the flow rate of combustion air being provided to the combustion chamber reducing standby heat loss. An actuator is in fluid communication with a fuel supply line such that when pressurized fuel is provided to the burner, the pressurized fuel causes the actuator to move the damper to an open position to permit operative combustion air delivery to the combustion chamber during firing periods of the water heater.
