Publication number: 20150093295Abstract: A distributor for a circulating dry scrubber reactor includes a venturi section with a venturi section wall extending from a venturi section inlet to a venturi section outlet along a longitudinal axis, with the venturi section inlet connected to an inlet plenum and the venturi section outlet connected to a circulating dry scrubber reactor. A hub is mounted within the venturi section wall with an annular converging-diverging flow path defined between the venturi section wall and the hub for distribution of gas flow from the venturi section outlet into a circulating dry scrubber reactor space and for maintaining stable bed fluidization in a CDS system at a comparatively low system pressure loss.Type: ApplicationFiled: October 9, 2014Publication date: April 2, 2015Inventors: Matthew Quitadamo, Kimbal Hall, Martin J.

Patent number: 8709348Abstract: Circulating dry scrubbing (CDS) systems and methods utilizes a particle classification unit operation to separate unreacted sorbent (such as lime, limestone, or sodium-based sorbent) such that a reactive fraction of the cut stream may be selectively recovered to a flue gas scrubbing system. This reduces the amount of fresh sorbent that must be supplied for pollutant removal.Type: GrantFiled: June 4, 2013Date of Patent: April 29, 2014Assignee: Babcock Power Development LLCInventors: James K. Neathery, Angelos Kokkinos, James D. Dougherty, Matthew Quitadamo

Publication number: 20090011913Abstract: The invention provides a tire and a roll wheel assembly used to crush material in a pulverizer including a generally toroidal body having a crushing surface on the outer periphery thereof. The crushing surface is configured and adapted to contact and crush the material within the pulverizer. At least one beveled surface is defined on an inner periphery of the body. The beveled surface is configured and adapted to engage a wedge disposed on a roller wheel of a roll wheel assembly to hold the tire on the roller wheel. The invention also provides a method of securing a tire to a roller assembly in a pulverizer for crushing material.Type: ApplicationFiled: July 2, 2007Publication date: January 8, 2009Applicant: Babcock Power Inc.Inventors: Qingsheng Lin, Angelos Kokkinos, Joshua Creelman, Gregory L. Morse, Ivo Slezak

Patent number: 6318277Abstract: A method and apparatus for reducing NOx emissions in a furnace having a main combustion zone with a waterwall and apparatus for supplying main combustion air and fuel to the main combustion zone, also reduces unburned carbon and waterwall corrosion in the furnace. The method involves providing at least one lower overfire air injector at a first level over the main combustion zone of the furnace for supplying overfire air to create a lower overfire air zone in the furnace over the main combustion zone and at least one upper overfire air injector at a second level over the lower overfire zone for supplying overfire air to create an upper overfire air zone in the furnace over the lower overfire zone. The overfire air in the lower and upper overfire air zones are supplied at a rate for reducing the stoichiometry in the main combustion zone which reduces unburned carbon and a corrosive reducing atmosphere in the furnace.Type: GrantFiled: September 13, 1999Date of Patent: November 20, 2001Assignee: The Babcock & Wilcox CompanyInventor: Angelos Kokkinos

Patent number: 4672900Abstract: A tangentially-fired furnace is disclosed in enough detail to illustrate the location of injection ports for excess air above the fireball of the combustion chamber to eliminate the swirl of the flue gases as the flue gases flow into the convection section, in order to produce a uniform mass flow and temperature pattern of the flue gases over the cross section of the furnace exit.Type: GrantFiled: March 10, 1983Date of Patent: June 16, 1987Assignee: Combustion Engineering, Inc.Inventors: Richard W. Santalla, Angelos Kokkinos, Robert J. Collette, Michael S. McCartney

Patent number: 4274343Abstract: An improved fuel-air admission assembly having a plate disposed along the longitudinal axis of the coal delivery pipe. The leading edge of the plate is orientated across the inlet end of the coal delivery pipe so that the high coal concentration portion of the primary air-pulverized coal stream discharging along the outer radius of the main fuel pipe outlet elbow is separated from the low coal concentration portion of the primary air-pulverized coal stream discharging along the inner radius of the main fuel pipe outlet elbow. The trailing edge of the plate is orientated across the outlet end of the coal delivery pipe so that the high and low coal concentration streams are directed into the furnace through separate nozzles.Type: GrantFiled: April 13, 1979Date of Patent: June 23, 1981Assignee: Combustion Engineering, Inc.Inventor: Angelos Kokkinos
