Title: Fluidized bed heat exchanger with water cooled air distributor and dust hopper

Full Record
Other Related Research

Abstract

A fluidized bed heat exchanger is provided in which air is passed through a bed of particulate material containing fuel. A steam-water natural circulation system is provided for heat exchange and the housing of the heat exchanger has a water-wall type construction. Vertical in-bed heat exchange tubes are provided and the air distributor is water-cooled. A water-cooled dust hopper is provided in the housing to collect particulates from the combustion gases and separate the combustion zone from a volume within said housing in which convection heat exchange tubes are provided to extract heat from the exiting combustion gases.

Internal dust recirculation system for a fluidized bed heat exchanger

Patent Gamble, Robert L [Wayne, NJ]; Garcia-Mallol, Juan A [Morristown, NJ]

A fluidized bed heat exchanger in which air is passed through a bed of particulate material containing fuel disposed in a housing. A steam/water natural circulation system is provided in a heat exchange relation to the bed and includes a steam drum disposed adjacent the bed and a tube bank extending between the steam drum and a water drum. The tube bank is located in the path of the effluent gases exiting from the bed and a baffle system is provided to separate the solid particulate matter from the effluent gases. The particulate matter is collected and injected back intomore » the fluidized bed. « less

A fluidized bed heat exchanger in which air is passed through a bed of particulate material containing fuel disposed in a housing. A steam/water natural circulation system is provided and includes a steam drum disposed adjacent the fluidized bed and a series of tubes connected at one end to the steam drum. A portion of the tubes are connected to a water drum and in the path of the air and the gaseous products of combustion exiting from the bed. Another portion of the tubes pass through the bed and extend at an angle to the upper surface of themore » bed. « less

Gas distributor for fluidized bed coal gasifier

Patent Worley, Arthur C [Mt. Tabor, NJ]; Zboray, James A [Irvine, CA]

A gas distributor for distributing high temperature reaction gases to a fluidized bed of coal particles in a coal gasification process. The distributor includes a pipe with a refractory reinforced lining and a plurality of openings in the lining through which gas is fed into the bed. These feed openings have an expanding tapered shape in the downstream or exhaust direction which aids in reducing the velocity of the gas jets as they enter the bed.

Heat exchanger support apparatus in a fluidized bed

Patent Lawton, Carl W [West Hartford, CT]

A heat exchanger is mounted in the upper portion of a fluidized combusting bed for the control of the temperature of the bed. A support, made up of tubes, is extended from the perforated plate of the fluidized bed up to the heat exchanger. The tubular support framework for the heat exchanger has liquid circulated therethrough to prevent deterioration of the support.

Circulating fluidized bed connected to a desublimating heat exchanger

Patent Baxter, Larry; Baxter, Andrew; Mansfield, Eric; ...

Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a circulating fluidized particle bed cooled by an out-bed heat exchanger to desublimate the solid form of condensable vapors from the process stream. Gas and solids may be sorted in a separator, and the solids may then be subcooled in a heat exchanger. The condensable vapors may be condensed on the bed particles or in the heat exchanger while the light gases from the process stream, which are not condensed, form a separated light-gas stream.
