Reactor system and solid fuel composite therefor

摘要

A reactor system includes a fluidized-bed. A fuel and a sulfur absorbent material are eluted through the fluidized-bed. The reactor system may include a heat exchanger having a heat-exchanging portion within a heating zone of the reactor that is hermetically sealed from the heating zone. The reactor may include loose particles of an inert bed material for forming the fluidized-bed. A feed system may be provided to inject a solid fuel composite that includes a mixture of a solid, carbonaceous fuel and a solid reagent into the reactor.

主权项

1. A power generator system comprising:
a fluidized-bed reactor having a height substantially greater than diameter, the fluidized bed including a plurality of axially spaced apart heating zones permitting separate injection of fuel thereto, each heating zone having resident loose particles therein and being operable to generate heat in a fluidized bed of the resident loose particles; a heat exchanger carrying supercritical carbon dioxide and having a heat-exchanging portion within the fluidized bed of each of the plurality of heating zones and that is hermetically sealed from the plurality of heating zones, the heat-exchanging portion comprising a main supply tube centrally located within and perpendicular to a plurality of horizontal layers of tubing each spaced apart from an adjacent horizontal layer of tubing, wherein each of the horizontal layers of tubing is oriented at an acute angle angled to the adjacent horizontal layer of tubing; and a steam-powered electric generator in thermal communication with the heat exchanger.
