Appl. No.:

09/643530

Assignee:

Alstom Power N.V. - Amsterdam

International Classification:

F23L 1502

US Classification:

165 8, 165 6, 165 4

Abstract:

A method for constructing a rotor of an air preheater having a plurality of diaphragm plates dividing the rotor into a number of wedge-shaped compartments. Each compartment includes compartment components such as a rotor shell plate, a hot end rotor angle, a cold end rotor angle, and one or more stay plates and means for locating at least a portion of each of the components within the compartment. The diaphragm plates are manufactured by marking at least one index location associated with each compartment component on each diaphragm plate blank utilizing a template identifying the index locations and forming an opening at each index location. Each compartment is assembled by positioning a first diaphragm plate adjacent to a second diaphragm plate and locating each compartment component between the adjacent diaphragm plates by engaging the locating means of the component in an associated opening in one of the diaphragm plates. The locating means may comprise at least one tab extending from each of the sides of the compartment components. The tabs are inserted into the associated opening in one of the diaphragm plates to locate the component.

International Classification:

F23L 1502

US Classification:

165 9, 165 8, 277370, 277922, 277549

Abstract:

A bypass seal for a rotary regenerative air preheater includes primary and secondary seal leaves that are joined at a single position longitudinally intermediate their first and second sends. The first end portion of the primary seal leaf extends longitudinally beyond the first end of the secondary seal leaf and the second end portion of the secondary seal leaf extends longitudinally beyond the second end of the primary seal leaf. When installed in the air preheater, the first end portion of the primary seal leaf of each bypass seal in one of the seal rings overlaps the second end portion of the secondary seal leaf of an adjacent bypass seal in the seal ring.

Assignee:

Alstom (Switzerland) Ltd - Baden

International Classification:

F23L 1502

US Classification:

165 8, 165 10, 165 4

Abstract:

A semi-modular rotor module for an air preheater having a circular rotor includes a lug assembly having a lug front, a lug back spaced radially outward from the lug front, and cold end and hot end lug members. The lug front and lug back each extend longitudinally from a first end to a second end, with the cold end lug member being mounted to the first ends of the lug front and the lug back and the hot end lug member being mounted to the second ends of the lug front and the lug back. A single main diaphragm extends radially from an inner end portion to an outer end portion, with the inner end portion being mounted to the lug front on a first side of the lug assembly. The outer end portion is mounted to a rotor shell which is spaced radially outward from the lug back. At least one intermediate diaphragm extends radially from an inner end portion, mounted to the lug back at a position intermediate the first and second sides of the lug assembly, to an outer end portion mounted to the rotor shell.

US Classification:

110345, 42324401, 431 2, 700274

Abstract:

A method and apparatus is provided for use in combustion system for capturing gas phase pollutants such as SO. In one example, the invention uses a computer model to model the combustion system. Particles are injected into the combustion system to capture the gas phase pollutants. The model is used to determine the injection location, as well as the size and amount of the particles to be injected.

Robin B. Rhodes - Wellsville NY

Assignee:

ABB Air Preheater, Inc. - Wellsville NY

International Classification:

F23L 1502

US Classification:

165 9

Abstract:

The gas flow bypass around the heating elements in a regenerative air preheater is reduced by the use of floating bypass seals which are placed in the rotor compartments between stacked heating elements. The seals comprise a frame with an open center with the peripheral frame portion bridging the gaps between the heating elements and the sides of the compartments. The seals may be adjustable and may include a deformable edge seal to actually contact and seal against the sides.

Inventors:

Robin B. Rhodes - Wellsville NY

Assignee:

The Air Preheater Company, Inc. - Wellsville NY

International Classification:

F28D 712

US Classification:

165142

Abstract:

A concentric tube type recuperative heat exchanger that includes an outer transparent tube 22 and an inner metallic tube 24 connected to suitable headers 12 and 14. The outer tube 24 is closed at the bottom end and open at the top end in order that cool air may be directed down through the open ended inner tube and up through the annular space therebetween where it may accept radiant energy transmitted through transparent tube 22. A tubular heat shield 36 of apertured metal lying in the annular space between tubes absorbs radiant heat passing directly through transparent tube 22 and that which is reflected from inner tube 24. Shield 36 serves simultaneously as a means for increasing the turbulence of fluid flowing through the annular space between tubes and as a heat sink that absorbs heat radiated between tube walls.
