Publication number: 20140141381Abstract: The present invention harvests and utilizes fluidized bed drying technology and waste heat streams augmented by other available heat sources to dry feedstock or fuel. This method is useful in many industries, including coal-fired power plants. Coal is dried using the present invention before it goes to coal pulverizers and on to the furnace/boiler arrangement. Coal can be intercepted on current coal feed systems ahead of the pulverizers. Drying fuel, such as coal, is done to improve boiler efficiency and reduce emissions. A two-stage bed utilized in the process first “pre-dries and separates” the feed stream into desirable and undesirable feedstock. Then, it incrementally dries and segregates fluidizable and non-fluidizable material from the product stream. This is all completed in a low-temperature, open-air system. Elevation of fan room air temperature is also accomplished using waste heat, thereby making available to the plant system higher temperature media to enhance the feedstock drying process.Type: ApplicationFiled: October 21, 2013Publication date: May 22, 2014Applicant: GREAT RIVER ENERGYInventors: Charles W. Bullinger, Mark A. Ness, Nenad Sarunac, Edward K. Levy, Richard S. Weinstein, Dennis R. James

Patent number: 8523963Abstract: The present invention constitutes a heat treatment apparatus like a fluidized-bed dryer for heat treating a particulate material in a low temperature, open-air process. Preferably, available waste heat sources within the surrounding industrial plan operation are used to provide heat to the dryer. Moreover, conveyor means contained within the dryer can remove larger, denser particles that could otherwise impede the continuous flow of the particulate material through the dryer or plug the fluidizing dryer. This invention is especially useful for drying coal for an electricity generation plant.Type: GrantFiled: August 8, 2005Date of Patent: September 3, 2013Assignee: Great River EnergyInventors: Charles W.

Also included is an apparatus for segregating particulate by density and/or size including a fluidizing bed having a particulate receiving inlet for receiving particulate to be fluidized. This is useful for segregating contaminants like sulfur and mercury from the product stream.Type: GrantFiled: October 10, 2011Date of Patent: February 12, 2013Assignee: Great River EnergyInventors: Charles W.

Patent number: 7540384Abstract: An apparatus for segregating particulate by density and/or size including a fluidizing bed having a particulate receiving inlet for receiving particulate to be fluidized. The fluidized bed also includes an opening for receiving a first fluidizing stream, an exit for fluidized particulate and at least one exit for non-fluidized particulate. A conveyor is operatively disposed in the fluidized bed for conveying the non-fluidized particulate to the non-fluidized particulate exit. A collector box is in operative communication with the fluidized bed to receive the non-fluidized particulate. There is a means for directing a second fluidizing stream through the non-fluidized particulate as while it is in the collector box to separate fluidizable particulate therefrom.Type: GrantFiled: August 8, 2005Date of Patent: June 2, 2009Assignee: Great River EnergyInventors: Mark A Ness, Matthew P Coughlin, Edward K Levy, Nenad Sarunac, John M.

Patent number: 6701255Abstract: An emission measuring system and method provide an accurate, real-time calculation of a particular material emitted from an emission source. Specifically, a CEM system installed in an industrial stack can include a dilution probe located in the stack and a data analyzer that records and analyzes characteristic data of the materials sampled by the dilution probe. A dilution ratio is used to correct for the addition of dilution gas into the stack gas sample to determine the concentration of a particular material that is being emitted from the stack. The dilution ratio is based on a molar flow rate, which can be determined by using specific algorithms and measurements.Type: GrantFiled: April 30, 2001Date of Patent: March 2, 2004Assignee: PPL Electric Utilities Corp.Inventors: James P.

Patent number: 5197398Abstract: Processes and arrangements that provide for the separation of pyrite from coal in a fluidized bed. The processes provide for more efficient and complete stratification of the bed materials in a vertical direction, so that the very top layer of the fluidized ved is coal having a reduced pyrite content. The process includes feeding the coal to be cleaned on top of a layer of magnetite. The process also includes fluidizing the bed until bed-bubbling separation occurs in the absence of steady-state conditions. The cleaned top layer of coal having a reduced pyrite content is then separated from the refuse coal in the bottom of the bed.Type: GrantFiled: April 16, 1991Date of Patent: March 30, 1993Assignee: Electric Power Research InstituteInventors: Edward K.
