Nozzle For Feeding Combustion Media Into A Furnace
View pageUS Patent:
8413595, Apr 9, 2013
Filed:
Aug 26, 2009
Appl. No.:
12/547868
Inventors:
John Grusha - Bethlehem PA, US
Assignee:
R-V Industries, Inc. - Honey Brook PA
International Classification:
F23D 1/00
F23K 3/02
F23K 3/02
US Classification:
110104B, 110261, 110265, 431160
Abstract:
In a boiler furnace having nozzles for introducing combustion media such as air and coal, nozzle tip walls that have the greatest exposure to radiant heat and hot gases are provided with arrays of air holes that allow air to flow to the exposed sides of the walls from the opposite sides in order to reduce the temperature difference between the two sides and thereby reduce thermal distortion and damage resulting from oxidation.
Clustered Concentric Tangential Firing System
View pageUS Patent:
50204548, Jun 4, 1991
Filed:
Oct 31, 1990
Appl. No.:
7/606682
Inventors:
Todd D. Hellewell - North Granby CT

Michael S. McCartney - Bloomfield CT
Assignee:
Combustion Engineering, Inc. - Windsor CT
International Classification:
F23D 102
US Classification:
110264
Abstract:
A clustered concentric tangential firing system (12) particularly suited for use in fossil fuel-fired furnaces (10) and a method of operating such furnaces (10) equipped with a clustered concentric tangential firing system (12). The clustered concentric tangential firing system (12) includes a windbox (20), a first cluster of fuel nozzles (38,40) mounted in the windbox (20) and operative for injecting clustered fuel into the furnace (10) so as to create a first fuel-rich zone therewithin, a second cluster of fuel nozzles (68,70) mounted in the windbox (20) and operative for injecting clustered fuel into the furnace (10) so as to create a second fuel-rich zone therewithin, an offset air nozzle (56) mounted in the windbox (20) and operative for injecting offset air into the furnace (10) such that the offset air is directed away from the clustered fuel injected into the furnace (10) and towards the walls of the furnace (10), a close coupled overfire air nozzle (78) mounted in the windbox ( 20) and operative for injecting close coupled overfire air into the furnace (10), and a separated overfire air nozzle (90) mounted in the window (20) and operative for injecting separated overfire air into the furnace (10).
Split Nozzle Tip For Pulverized Coal Burner
View pageUS Patent:
46340548, Jan 6, 1987
Filed:
Mar 14, 1985
Appl. No.:
6/712454
Inventors:
John Grusha - Windsor Locks CT
Assignee:
Combustion Engineering, Inc. - Windsor CT
International Classification:
F23K 302
US Classification:
239423
Abstract:
An improved nozzle tip (30) which provides enhanced ignition and stabilization of pulverized fuel flames in furnaces operating at low load. The nozzle tip (30) comprises open-ended inner and outer shells (32,34) mounted to the fuel delivery pipe (12) and defining a flow passageway within the inner shell through which the pulverized fuel is directed into the furnace and an annular flow passageway (50) between the inner and outer shells through which additional air is directed into the furnace. A pair of diverging splitter plates (41,42) are disposed within the inner shell (32) so as to divide the flow passageway therethrough into two separate, diverging subpassages (52,54) so that the pulverized fuel stream discharging from the fuel delivery pipe is split into first and second streams (60,70) which pass from the nozzle tip (30) into the furnace in a diverging manner thereby establishing an ignition stabilizing pocket in the low pressure zone (80) created between the diverging fuel streams.
Nozzle For Feeding Combustion Providing Medium Into A Furnace
View pageUS Patent:
62604910, Jul 17, 2001
Filed:
Sep 13, 1999
Appl. No.:
9/394417
Inventors:
John Grusha - Bethlehem PA
Assignee:
Foster Wheeler Corporation - Clinton NJ
International Classification:
F23D 100
US Classification:
110261
Abstract:
A nozzle for feeding combustion maintaining medium into a furnace at high temperature conditions includes a nozzle tip, at least partly protruding into the furnace, and a feeding mechanism for feeding the combustion medium from a source of the medium to the nozzle tip. The nozzle tip includes a mainly open ended outer shell, an air cooling zone, a shroud, and an air channel. The outer shell includes a first end wall portion in flow connection with the feeding mechanism and a second end wall portion protruding into the furnace. The cooling zone is formed on the interior side of at least a portion of the second end wall portion of the outer shell, by providing an air flow along the interior side. The shroud includes a shroud wall portion disposed to cover at least a portion of the first end wall portion of the outer shell. The shroud channel is formed between the shroud wall portion of the shroud and the first end wall portion of the outer shell, for discharging from the shroud channel an air shroud flow along the exterior side of the second end wall portion of the outer shell.
Nozzle For Feeding Combustion Media Into A Furnace
View pageUS Patent:
20230061105, Mar 2, 2023
Filed:
Aug 31, 2021
Appl. No.:
17/462838
Inventors:
- Honey Brook PA, US
John Grusha - Shoemakersville PA, US
John Grusha - Shoemakersville PA, US
Assignee:
R-V Industries, Inc. - Honey Brook PA
International Classification:
F23D 1/00
Abstract:
In a nozzle for feeding a combustible medium such as coal particles along with air into a furnace, the exit end of each splitter plate in the nozzle is reinforced by a stiffener having an external cross-sectional shape in the form of a continuous curve proceeding outward and forward from a first surface of the plate to a first location, inward from the first location to a second location beyond the level of an opposite second surface of the plate, and inward and rearward from the second location to the second surface. The stiffener can be hollow, and can also be provided with openings for the flow of cooling air from the interior to the exterior of the stiffener. The continuous curvature of the exterior of the stiffener avoids recirculating flow at locations adjacent the stiffener and thereby minimizes flame attachment and deposition of ash or fuel sediment onto the reinforced splitter plates.
