Patent number: 9764281Abstract: A flue gas stream arising from fossil fuel fired sources containing nitrogen oxide contaminants is conveyed through an exhaust duct into a quencher. In the quencher aqueous medium is sprayed into contact with the flue gas stream. The quenched flue gas stream is mixed with ozone distributed at a high velocity in a sub-stoichiometric amount for partial oxidation of NOxto form NO2 and prevent the formation of N2O5. The flue gas containing NO2 is absorbed into an acidic medium of a wet scrubber to form nitrous acid. In the scrubber the nitrous acid is mixed with selected compounds of ammonia to decompose the nitrous acid for release of nitrogen. With this process the consumption of ozone and the operating costs associated therewith eliminate the requirement to dispose of nitrate recovered from the scrubber purge stream.Type: GrantFiled: December 18, 2015Date of Patent: September 19, 2017Assignee: Cannon Technology, Inc.Inventor: Naresh J Suchak

Patent number: 8865098Abstract: In a method for removing a portion of contaminants, such as nitrogen oxides, from an exhaust gas stream of a combustion process, the exhaust gas stream is separated into two or more gas streams. At least one of the two or more gas streams is treated first by mixing with ozone. The treated gas stream is then fed to a scrubber where it is recombined with the untreated gas stream. Excess ozone present in the treated gas stream is consumed by oxidation of contaminants in the untreated gas stream before the combined gas stream is released to the atmosphere. The portion of the gas stream separated for mixing with ozone directly correlates to the amount of nitrogen oxides that are desired to be removed from the stream.Type: GrantFiled: October 15, 2013Date of Patent: October 21, 2014Assignee: Cannon Technology, Inc.Inventor: Naresh J.

Patent number: 7702424Abstract: A load control management protocol, system, and method that address many different customers, individually, in geographic groups, or in other predefined groups to control at least one or more electrical power consuming appliances are disclosed. The computer-implemented protocol provides wired and wireless communication schemes that enable a utility to quickly and efficiently communicate commands and messages to end user devices. Specific electrically powered appliances and certain uses of electricity can therefore be managed by communicating with the controllers of those appliances, providing management of a utility load during peak price and consumption periods to prevent delivery interruptions.Type: GrantFiled: October 30, 2007Date of Patent: April 20, 2010Assignee: Cannon Technologies, Inc.Inventors: Joel Cannon, Robert Cox, Roger Rognli

Patent number: 7528503Abstract: Control of a variable output appliance of a small energy consumer participating in an electrical load shedding program. A baseline operating characteristic of the appliance is determined for ordinary operation (such as in an absence of any load shedding requirements). An amount by which to reduce output of the appliance is determined in accordance with the load shedding program. Operation of the appliance is controlled to achieve the output reduction in accordance with the load shedding. This approach enables providing incentive for the small energy consumer to participate in the load shedding program, the incentive being based on the amount by which output is reduced, thereby representing a reduction of actual energy consumption for that small energy consumer.Type: GrantFiled: July 24, 2006Date of Patent: May 5, 2009Assignee: Cannon Technologies, Inc.Inventors: Roger Rognli, Brian Ahlsten

Patent number: 7400150Abstract: Systems and methods for remotely monitoring and detecting faults in power distribution systems. In one embodiment, a remote fault monitoring system comprises a plurality of remote fault detection devices distributed on a power distribution network, and a monitoring station. Each remote detect device includes a first electrical parameter measurement circuit electrically or electromagnetically coupled to a neutral power distribution circuit conductor, and a second electrical parameter measurement circuit electrically or electromagnetically coupled to a power distribution circuit ground conductor. The monitoring station receives measurements transmitted by the remote fault detection devices and determines from the measurements whether a fault intermediate a pair of adjacent remote fault detection devices has occurred.Type: GrantFiled: January 19, 2006Date of Patent: July 15, 2008Assignee: Cannon Technologies, Inc.Inventor: Michael Cannon

Patent number: 7355412Abstract: Remote indication devices are each a combination of electrical parameter measurement circuitry, a CPU, and a communication device. Each remote indication device is electrically or electromagnetically coupled to a power distribution circuit conductor to monitor the current flowing in the conductor. The monitored conductor may be an energized power line (“phase”), or a current return line (“neutral”). In either case, the direction of power transfer at each measurement point can also be monitored by each remote indication device. Each remote indication device processes the monitored electrical current information to convert it into a form suitable for data transmission. The information is then presented to a monitoring station. The monitoring station collects and analyzes the electrical current information from the plurality of remote indication devices and is programmed to identify one or more particular power line segments that appear to have a fault.Type: GrantFiled: August 5, 2005Date of Patent: April 8, 2008Assignee: Cannon Technologies, Inc.Inventor: Michael Cannon

Patent number: 7355301Abstract: A method for detecting line under voltage (LUV) events and initializing load shedding of loads located near the electrical disturbance without customer and utility intervention. In one example embodiment, the LUV detection system samples a primary voltage source at regular time intervals, thereby generating a series of voltage readings, and compares the voltage readings to an under voltage trigger threshold. If an under voltage condition is detected, then an under voltage in-response cycle is initialized that controls the electrical load. When the voltage readings decrease to below a voltage-power fail level, a plurality of load restore counter values are stored in memory before the load is shed from the primary voltage source. A restore response is then initialized after the voltage level rises above a restore value and is maintained above the restore value for an under voltage out-time period.Type: GrantFiled: February 25, 2004Date of Patent: April 8, 2008Assignee: Cannon Technologies, Inc.Inventors: William R. Ockert, Robert Cox, Kevin Allmaras

Patent number: 7242114Abstract: A method for detecting line under frequency (LUF) events and initializing load shedding of loads located near the electrical disturbance without customer and utility intervention is disclosed. In one example embodiment, the LUF detection system measures the time period of each power line cycle and then compares the measured time period to a utility-configurable trigger period. If the cycle length is greater than or equal to the trigger period, a counter is incremented. If the cycle is less than the trigger period, the counter is decremented. If the counter is incremented to a counter trigger, an under-frequency condition is detected and the LUF response either controls the load or temporarily disconnects it. A restore response is initialized after the frequency rises above a restore value and an under-frequency counter counts down to zero.Type: GrantFiled: April 15, 2004Date of Patent: July 10, 2007Assignee: Cannon Technologies, Inc.Inventors: Joel R.
