Boosted No-Lance Injection Systems And Methods
US Patent:
2013012, May 23, 2013
Filed:
Sep 6, 2012
Appl. No.:
13/605322
Inventors:
Lewis B. Benson - Sewickley PA, US
Brian S. Higgins - San Francisco CA, US
Brian S. Higgins - San Francisco CA, US
International Classification:
B01D 53/12
US Classification:
95108, 96150
Abstract:
A boosted no-lance injection system (BNLS) and methods of operating a combustion system to reduce acid gas or metal emissions in the flue gas is shown and described. In one embodiment, a BNLS includes an injection device, a high volumetric flow air mover, a transport air mover, a sorbent hopper and a mounting apparatus. In other embodiments, a method of operating a combustion system includes positioning the BNLS to inject into the ductwork, applying transport air and sorbent into the ductwork, and applying the high volumetric flow air into the ductwork. The result is methods and systems for reducing acid or metal emissions in the flue gas.
Method For Producing Activated Lime For Removal Of Acid Gases From A Combustion Gas
US Patent:
2009022, Sep 3, 2009
Filed:
Apr 13, 2006
Appl. No.:
10/583008
Inventors:
Lewis B. Benson - Sewickley PA, US
J. Casey Schulz - Crescent PA, US
J. Casey Schulz - Crescent PA, US
International Classification:
C04B 2/02
US Classification:
423636
Abstract:
An activated lime for use in removing acid gases from a combustion gas stream is produced by thermally decomposing calcium hydroxide to calcium oxide through contact or the calcium hydroxide with a heated gas stream at a temperature or between 750-950° F. for a time sufficient to produce a calcium oxide having a specific surface area of between 30-48 square meters per gram, and collecting the product so produced.
