<p>In apparatus for using focused solar radiation to gasify coal and other carbonaceous materials, incident solar radiation is focused from an array of heliostats (19) onto a tower-mounted secondary mirror (21) which redirects the focused solar radiation down through a window (12) onto the surface of a vertically-moving bed of coal, or a fluidized bed of coal, contained within a gasification reactor (11). The reactor is designed to minimize contact between the window and solids in the reactor. Steam introduced into the gasification reactor reacts with the heated coal to produce gas consisting mainly of carbon monoxide and hydrogen, commonly called "synthesis gas", which can be converted to methane, methanol, gasoline, and other useful products. The steam is generated at the rear surface of the secondary mirror. <IMAGE></p> |
