  • Patent number: 6659026
    Abstract: A control system for providing improved control over the combustion process of a multiple-intertube pulverized-coal burner that commonly forms a portion of a roof-fired boiler. The system utilizes actual mass fuel flow measurements to calculate corrected, optimal secondary and interjectory air demands. The corrected secondary and interjectory air demands are used by a proportional and integral control loop to regulate the respective supply of secondary and interjectory air to the combustion process of each in-service burner. The control system allows for optimal combustion of the fuel and a reduction in NOx emmissions.

  • Patent number: 6562108
    Abstract: A method of removing a liquid entrained in a gas moving at a velocity in an upward direction from a base to a top of a stack comprising the steps of imparting a swirling direction to the velocity of the gas adjacent the base of the stack and then recovering at least some of the liquid adjacent the top of the stack. Also disclosed is an apparatus for removing a liquid entrained in a gas in a stack having a base and a top comprising at least one duct having a longitudinal axis entering the stack adjacent said base and at least one vertical vane disposed at and angled to the longitudinal axis of the duct and a collector adjacent the top of the stack for recovering liquid.

  • Patent number: 6518734
    Abstract: A system and method for creating capacitor-based electrical energy storage modules and electrical energy storage systems assembled therefrom. Submodules having a plurality of capacitors capable of storing electrical energy are used in different combinations to create electrical energy storage modules. Preferably, a number of submodules are placed into corresponding receptacles within an enclosure or cabinet, wherein the submodules become electrically connected. The number of submodules installed in a cabinet is determined by the power output desired, and the space constraints of the area in which the cabinet will be located. One cabinet of one or more submodules, or a plurality of interconnected cabinets of one or more submodules, may form an electrical energy storage module. The module may be designed to output either DC or AC electric power, and is preferably equipped with a power conversion system and/or communication and control electronics to control the charging and discharging thereof.
