摘要： The present publication discloses a method and an apparatus for drying the fuel used for firing a fluidized-bed boiler (1). The hot, inert solids of the fluidized bed are circulated by a regulated rate from the furnace (2) to a simple dryer (11) incorporated into the fuel feed line (7) to the boiler (1), whereby the fuel is dried and steam is generated. By virtue of controlled bed solids recirculation, a constant temperature of the dryer (11) can be maintained, thus permitting the omission of all heat transfer surfaces from the dryer (11). The nearly clean steam released from the drying process is routed from the dryer (11) to useful applications. (FIG. 1)

摘要： A fluidized bed reactor in which a heat exchanger is located adjacent the reactor with each enclosing a fluidized bed and sharing a common wall including a plurality of water tubes. A mixture of flue gases and entrained particulate materials from the fluidized bed in the reactor are separated and the separated particulate material is passed to the fluidized bed in the heat exchanger. Coolant is passed in a heat exchange relation with the separated materials in the heat exchanger to remove heat from the materials after which they are passed to the fluidized bed in the reactor. Auxiliary fuel is supplied to the heat exchanger for combustion to control the temperature of the coolant. When the system of the present invention is utilized to generate steam the coolant can be controlled to match the requirements of a steam turbine.

摘要： A fluidized bed combustion system and method in which a recycle heat exchange section, including an inlet compartment and a heat exchange compartment, is located within an enclosure housing the furnace section of the combustion system. The flue gases and entrained solids from a fluidized bed in the furnace section are separated, the flue gases are passed to a heat recovery section, and the separated particulate material is passed directly to the inlet compartment via a dipleg. The recycle heat exchange section includes a bypass chamber for permitting the separated solids to pass directly from the inlet compartment to the furnace section. Heat exchange tubes are provided in the heat exchange compartment to transfer heat from the separated material in the latter compartment to a fluid flow circuit for heating the fluid flow circuit. The separated material in the heat exchange compartment is passed back to the furnace section. Air is introduced into the inlet compartment below the dipleg and in alignment therewith to control the flow of separated material from the separator and therefore the recycle rate.

摘要： A reactor in which a furnace and a heat recovery area are provided. A bed of solid particulate material including fuel is supported in the furnace and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel. The products of combustion (or flue gases) pass upwardly through the furnace and transfer heat energy to the walls thereof to produce steam. Flue gases leaving the upper region of the furnace section are transported to a heat recovery area, which functions to remove additional heat energy from the flue gases for producing the steam. A flue gas by-pass system is provided which transports relatively hot flue gases from a lower region of the furnace section to the heat recovery area for improving isothermal operating conditions and optimizing reactor performance. One or more conduits pass flue gases directly from selected extraction points within the lower region of the furnace to an upper portion of the heat recovery area. A dust collector may be connected to the gas extraction conduits for separating particulate material from the flue gases, if needed.
