Abstract
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.
Claims24
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 heat exchanging fluid 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 to the adjacent horizontal layer of tubing;
- and
- a steam-powered electric generator in thermal communication with the heat exchanger.
A power generator system comprising:

- a heat exchanger carrying a heat exchanging fluid and having a heat exchanging portion within the fluidized bed of each of the plurality of heating zones, the heat-exchanging portion including a three dimensional tube arrangement including a plurality of spaced apart tubing layers and configured to distribute the resident loose particles through the fluidized bed to facilitate uniform transfer of the heat to the heat exchanging portion;
- and
- a steam-powered electric generator in thermal communication with the heat exchanger.
