Patent CA-2584855-A1 (CA)
Inventor: DEVAULT DOUGLAS J
IPC: F23J15/00
Filed: 2007-04-12
Abstract: The invention is related to a system for removal of moisture and contaminants from recirculated flue gas which is used for combustion in fossil fuel power plants The system includes a spray tower having an inlet at one end of the housing and an outlet at an opposite end of the housing for channeling the flue gas into and out of the housing. Sprayers are located in the housing for spraying the flue gas with a liquid reagent to remove contaminants, including SO2, from the flue gas. A  heat exchanger is integrally connected to the housing. The heat exchanger cools the liquid reagent before the reagent is sprayed onto the flue gas stream. The sprayers quench the flue gas stream with the cooled liquid reagent. The cooling of the liquid reagent to a temperature below the flue gas water vapor dew point improves the condensation of the water vapor in the flue gas during the spraying process.  The flue gas exits the system with a lower moisture content and is redirected to burner for combustion. As a result, the efficiency the combustion process will improve with less moisture in the flue gas.

Title: Low complexity adaptive channel estimation
Inventor: PIETRASKI PHILIP J
IPC: H04B1/69
Filed: 2005-11-30
Abstract: A channel estimation apparatus and method is provided for a wireless communication signal received from at least one relatively mobile wireless transmit/receive unit (WTRU). Predetermined filter coefficients having unique index values are stored in a memory device. An index generator matches estimation values of the mobile unit speed and SNR to a particular filter coefficient, and selects a corresponding index value, whereby the memory performs a look up function according to the index value and outputs a filter coefficient vector. The channel estimation of the wireless communication signal is taken from the output of the filter. Alternatively, a set of parallel filters which run continuously are used to produce several channel estimates, from which the final estimate is selected based on the associated lowest mean square error or highest SNR.
