An apparatus for burning coal to produce substantially pure hydrogen for use
in
fuel cells, together with "sequestration ready" carbon dioxide and a stream of
oxygen depleted air for powering gas turbines. The apparatus includes two fluidized
bed reactors and a third transfer line reactor. The first reactor is supplied with
coal particles or "char" and fluidized with high temperature steam. The second
reactor is fluidized with high temperature steam and the third reactor is fluidized
by compressed air. Solids circulated among these three reactors include a mixture
of materials containing coal, calcium compounds (present as CaO, CaCO3
and mixtures thereof) and iron compounds (present as FeO, Fe2O3
and mixtures thereof).
