摘要： A filter assembly for high temperature gases, such as from a circulating fluidized bed reactor, mounts monolithic ceramic filter elements within an upright vessel so that as the hot gas flows from the top toward the bottom of the vessel the gas passes through the elements with the clean gas discharged through a side wall of the vessel. The particle discharge is provided at the bottom of the vessel. Filter supporting elements within the vessel are cooled by cooling fluid, and pulse cleaning elements are associated with each of the filter elements. Flow directing elements within the vessel typically define a generally conical or pyramidal shaped flow directing surface. The flow directing elements may be refractory material bodies, or funnel shaped thin elements (e.g. of metal capable of withstanding high temperature), and may be mounted so that small amounts of movement are possible to accommodate thermal contraction or expansion.

摘要： In a fluidized bed reactor, nozzles are provided for distributing fluidizing gas from a windbox into the reactor while preventing the backflow of solid particles through the nozzle into the windbox. The nozzle defines an upper part of high heat and wear resistant material adapted to contact the mass of particles. At least one opening is defined in each nozzle through which fluidizing gas passes between the upper part and the windbox, and a solid, though porous, material abuts or defines the opening for allowing the passage of gas while preventing passage of solid particles. The nozzle may comprise a stand pipe having a sintered metal portion disposed below the upper part. Other constructions provide the solid mass as a metal wire mesh acid proof filter, or as a porous ceramic material, or as a high temperature ceramic material. The solid mass may have pores with a pore size of between about 50-1,000 micormeters. The solid mass may be defined by a pair of concentric adjacent porous ceramic tubes with different effective gas permeabilities. A horizontal solid metal ring may have openings in it, with the ring supported above the windbox so that gas can flow through the openings, the porous solid material sandwiched between the upper part and the ring.

摘要： In the filtering of high temperature (e.g. greater than 400.degree. C.) and high pressure (e.g. greater than 5 bar) gas--such as produced by pressurized fluidized bed combustion or gasification of coal--there is often a buildup of particles on the supporting elements for the filters, and on surrounding structures. This buildup of particles can damage the filter elements, or greatly reduce their effectiveness. This problem is avoided by periodically automatically cleaning the supporting and/or surrounding surfaces of the filters, as by directing high pressure gas streams at the supporting and/or surrounding surfaces. The filters may also be backflushed with compressed gas, as is conventional, at the same time as, or at different times than, when the supporting and/or surrounding structures are cleaned. Conduits with nozzles may be mounted directly on the supporting and/or surrounding surfaces and connected by a pipe with an automatically controlled valve to a source of high pressure fluid.

摘要： A method of burning solid fuel having low melting point alkaline compositions, such as alkali metal salts, particularly lignite and salty brown coal. The fuel is introduced into the reaction chamber of a circulating fluidized bed reactor, and is mixed prior to introduction to the reaction chamber with a reactant material capable of reacting with the low melting point alkaline compositions of the fuel to produce high melting point alkali metal compounds during combustion. The temperature in the reaction chamber is kept below the melting point of the formed alkali metal compounds. The reactant material comprises silica oxide or a metal oxide, or hydroxide, of the group consisting of aluminum, calcium, magnesium, iron, titanium, and mixtures of two or more thereof. Kaolin is particularly effective, especially when the molar ratio of Al/(Na and K) is at least 1.0.
