  • Patent number: 10725075
    Abstract: A method of evaluating an optimization system is disclosed. The system is transitioned from an on state to an off state. Data is collected at time intervals for a time period before and after the system is transitioned from the on state to the off state. The transitioning occurs while a load of a particular type is active. In one embodiment, the optimization system is a Volt/VAR Optimization (VVO) system.

  • Patent number: 8425850
    Abstract: Embodiments describe an arrangement for reducing the amount of LPA that reaches a NOx reducing apparatus such as a SCR system. The arrangement includes deflection elements, screens, means for dislodging any LPA that might become lodged in the screens, an aperture for removing the ash through, hoppers or collection means and an ash conveyance system. The arrangement is positioned in a region of ductwork with a reduced gas flow such as the SCR reactor. The screens are positioned relative to one another to direct the LPA downward toward an aperture for removal. In one embodiment the positioning of the screens creates a half-trough or inverted pyramid appearance when placed next to a vertical wall in the flue gas ductwork or the SCR reactor. The low point of the trough is in communication with the aperture allowing the LPA to exit the flue ductwork.

  • Publication number: 20090212140
    Abstract: The present invention is a system and method for reducing the size of a hygroscopic material while simultaneously drying the material at a relatively low temperature to a predetermined value during the reduction process. The present invention utilizes a preconditioning make-up air system to significantly dehumidify the make-up air to values in the range of 0.02 grains per pound of dry air while limiting the temperature of the make-up air exiting the preconditioning make-up air system to below a predetermined critical value. While not limited in its application to any one particular hygroscopic material, the present invention is particularly adapted to uses where the product is a temperature-sensitive, water adsorbing material such as sodium sesquicarbonate or trona ore.

  • Publication number: 20050201914
    Abstract: The present invention is a system and method for treating a flue gas stream to remove strong acid compounds selected from the group consisting of hydrofluoric acid (HF), hydrochloric acid (HCl), sulfuric acid (H2SO4), and sulfur trioxide (SO3) by injecting a sodium sorbent selected from the group consisting of sodium sesquicarbonate, sodium carbonate-bicarbonate, trona ore, mechanically refined trona ore, and trona into the flue gas stream, calcining substantially all of the sodium sorbent in the presence of the flue gas stream to form a soda ash, reducing the concentration of the at least one strong acid compound in the flue gas stream by reacting the at least one strong acid compound with the soda ash to form a sodium based by-product; and changing the chemistry of the flue gas stream to reduce the overall average resistivity of the particulate matter.

  • Patent number: 6900556
    Abstract: A large-scale, capacitor-based electrical energy storage and distribution system capable of effectuating load-leveling during periods of peak demand on a utility, and of effectuating a cost savings associated with the purchase of electrical energy. A capacitor or multitude of capacitors may be charged with electrical energy produced by the utility, such as during periods of low demand or low cost, and discharged during periods of high electrical energy consumption or high electrical energy cost. One or more capacitors may be located at a consumer's residence or business. Alternatively, a farm of capacitors may be provided at or near a utility, or at or near a location experiencing high demand. In another embodiment, one or more capacitors may be located in or on a vehicle, such as an automobile, a truck, or a train of a light rail system.
