摘要:
A hot solids process wherein a predetermined output, which is designed to be suitable for use as an input to a petrochemical process, is capable of being generated through the use of the hot solids process. The mode of operation of such a hot solids process is designed to be such that preferably a portion of the otherwise normally unusable product output, which is produced from a petrochemical process, is designed to be utilized as an input to the hot solids process for purposes of generating from the hot solids process the predetermined output that is suitable for use as an input to a petrochemical process.

In a method for operating a steam generator, a transport reactor is provided. Only a substantially pure oxygen feed stream is introduced into the transport reactor in an amount sufficient to maintain the transport reactor at or above a specific system load. The specific load is the system load when only the substantially pure oxygen feed stream is provided to the transport reactor at a minimum flow velocity for operating the transport reactor. A fuel is combusted in the presence of the substantially pure oxygen feed stream to produce a flue gas, which contains solid material. The solid material is separated from the flue gas and passed to a heat exchanger. The heat exchange may be one of a moving bed heat exchanger or a fluidized bed heat exchanger. The solid material is directed to the transport reactor to contribute to the combustion process.

A sealpot for a combustion power plant includes a downcomer standpipe which receives solids of the combustion power plant, a bed including a first end and a second opposite end, the first end connected to the downcomer standpipe, a discharge standpipe disposed at the second opposite end of the bed, and an orifice plate disposed between the bed and the discharge standpipe separating the discharge standpipe from the bed. The orifice plate includes apertures disposed at a height above the bed which allow transport of fluidized solids and gas through the orifice plate.

摘要:
A hot solids process operable selectively for combustion purposes and gasification purposes wherein a pre-identified product is selected from a group of products to be generated through the use of the hot solids process. Based on the nature of the pre-identified product, which is to be generated through the use of the hot solids process, a specific fuel from which the pre-identified product is capable of being derived is selected from a group of fuels. Then, from a group of reactors there is selected a first reactor, which is operable for generating in the first reactor the pre-identified product as an output from the first reactor. Thereafter, from a group of reactors, there is selected a second reactor, which is operable for effecting in the second reactor the conversion of air and of a predetermined carrier selected from a group of carriers to produce a predefined output from the second reactor.

摘要:
A fluidized bed combustion system (10) particularly suited for use to effect the incineration, i.e., combustion, therewith of wood waste/sludge mixtures that have high moisture and ash content which makes them difficult to burn. The fluidized bed combustion system (10) includes a fluidized bed combustor (12) embodying a fluidized bed (24) composed of bed solids. Air is injected into the fluidized bed (24) through an air distributor (28) to establish a first controlled fluidizing velocity zone and a second controlled fluidizing velocity zone therewithin. Material (42b) is introduced into the fluidized bed combustor (12) above the second controlled fluidizing velocity zone. Bed solids are projected from the first controlled fluidizing velocity zone to the second controlled fluidizing velocity zone whereupon the bed solids rain down upon the material (42b) and effect a covering thereof. The material (42b) is then dried and thereafter combusted. Inerts/tramp materials/clinkers as well as large diameter solids entrained with the material (42b) are segregated therefrom and then are removed (14,200) from the fluidized bed combustor (12).
