US Patent:

53933150, Feb 28, 1995

Filed:

Jul 28, 1994

Appl. No.:

8/282518

Inventors:

Michael G. Alliston - Lewisburg PA
Brian T. Sinn - Williamsport PA

Assignee:

Tampella Power Corporation - Williamsport PA

International Classification:

B01D 4512

US Classification:

55269

Abstract:

A cyclone separator for a solids-laden process gas from a fluidized bed boiler or reactor also provides a pressure seal and heat exchanger surfaces for the reactor or boiler. The cyclone includes a cylindrical main housing with a longitudinal axis. The housing is made of membrane wall construction. A portion of the tubes are bent outwardly to form an inlet which communicates with the main housing for receiving the solids-laden process gas from the boiler or reactor. Solids are separated from the solids-laden process gas as they swirl together in the main housing of the cyclone separator. A partition wall is disposed at the lower section of the main housing around the longitudinal axis for defining an outer chamber and an inner chamber adjacent the outer chamber. Gas is provided to the outer and inner chambers for creating fluidized beds of the solids in the outer and inner chambers. Solids are passed from the inner chamber to the outer chamber through an underflow port in the partition wall.

Tampella Power Corporation - Williamsport PA

International Classification:

B01J 824

US Classification:

422143

Abstract:

A biased air distribution grid is used to promote solids entrainment and dense bed internal mixing for the bed material of a fluidized bed reactor. The air distribution grid distributes air at a high velocity zone having a velocity ranging from 11 to 50 feet per second and a low velocity zone having a velocity ranging from 3 to 10 feet per second. The high velocity zone and the low velocity zone provide an improved lateral mixing for the reactor.

Appl. No.:

6/663533

Inventors:

Brian T. Sinn - Williamsport PA

Assignee:

Foster Wheeler Energy Corporation - Livingston NJ

International Classification:

F27B 1508

US Classification:

48197R

Abstract:

A method of operating a fluidized bed in which a bed of particulate combustible material is disposed on a perforated plate and air is introduced through the plate and into the bed to fluidize and promote the combustion of the material. Additional particulate material, of a size less than that of said combustible particulate material, is introduced to the bed so that it is entrained in the air to maintain the combustible material in the bed.

International Classification:

F22G 500

US Classification:

1224791

Abstract:

A method and system for controlling reheater steam temperature is disclosed. The method can be carried out by selectively adjusting the flow of superheated steam into a superheater positioned between two reheater sections in the convection pass of a carbonaceous fuel boiler system.

International Classification:

B01D 4512

US Classification:

55269

Abstract:

A cyclone separator for a solids-laden process gas from a reactor also provides a pressure seal for the reactor. The cyclone includes a main housing with a longitudinal axis. The housing is made of a membrane wall construction having a plurality of tubes arranged around the axis and encased within membrane wall panels. A portion of the tubes are bent outwardly to form an inlet which communicates with the main housing for receiving the solids-laden process gas from the boiler. Solids are separated from the solids-laden process gas as they swirl together in the main housing of the cyclone separator. A partition wall is disposed at the lower section of the main housing around the longitudinal axis for defining an outer chamber and an inner chamber adjacent to the outer chamber. Gas is provided to the outer and inner chambers for creating fluidized beds of the solids in the outer and inner chambers. Solids are passed from the inner chamber to the outer chamber through an underflow port in the partition wall.
