A gasifierincludes a first chemical process loophaving an exothermic oxidizer reactorand an endothermic reducer reactor. CaS is oxidized in air in the oxidizer reactorto form hot CaSOwhich is discharged to the reducer reactor. Hot CaSOand carbonaceous fuel received in the reducer reactorundergo an endothermic reaction utilizing the heat content of the CaSO, the carbonaceous fuel stripping the oxygen from the CaSOto form CaS and a CO rich syngas. The CaS is discharged to the oxidizer reactorand the syngas is discharged to a second chemical process loop. The second chemical process loophas a water-gas shift reactorand a calciner. The CO of the syngas reacts with gaseous HO in the shift reactorto produce Hand CO. The COis captured by CaO to form hot CaCOin an exothermic reaction. The hot CaCOis discharged to the calciner, the heat content of the CaCObeing used to strip the COfrom the CaO in an endothermic reaction in the calciner, with the CaO being discharged from the calcinerto the shift reactor

A system for reducing carbon dioxide emissions from gasses generated in burning fossil fuel, includes a vessel, separator and reheater. The upper portion of the vessel receives downward flowing, first type solid particles capable of absorbing heat from upward flowing gasses and second type solid particles capable of capturing carbon dioxide from the gasses. The separator separates the second type solid particles with the captured carbon dioxide from the gasses discharged from the first vessel discharge, and directs the separated second type solid particles with the captured carbon dioxide to a separator discharge. The reheater directs the first type solid particles and the second type solid particles with the captured carbon dioxide in a downwardly flow to a first reheater discharge, such that heat from the first type solid particles causes the captured carbon dioxide to be released from the second type solid particles.

A recuperative and conductive heat transfer system ( &prime;) that is operative to effect therewith the heating within the second portion ( &prime;) of the heat transfer system ( &prime;) of a &ldquo;working fluid&rdquo; flowing through the heat s transfer surfaces ( &prime;) as a consequence of the transfer thereto by conduction of heat from a multiplicity of regenerative solids ( &prime;). The multiplicity of regenerative solids ( &prime;) derive their heat from a recuperation thereby within the first portion ( &prime;) of the heat transfer system ( &prime;) from either an internally generated or an externally generated source of heat ( &prime;).
