This invention relates to a power recovery process in waste steam/CO.sub.2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.

A method and an apparatus for mixing and pre-burning a gasification agent are disclosed. The apparatus includes a gasifier body comprising a furnace chamber, a gas distribution plate, and a gasification agent mixing chamber. The apparatus also includes a pulverized coal transport pipe and a carbon-containing fly ash transport pipe, which respectively feed a pulverized coal and a carbon-containing fly ash to a middle portion of the gasification agent mixing chamber. The apparatus further includes a gasification agent transport pipe that feeds a gasification agent to a bottom of the gasification agent mixing chamber. The present disclosure advocates a pre-burning process of the gasification agent that involves the pulverized coal and the carbon-containing fly ash, which heats the gasification agent as the gasification agent is being fed to the circulating fluidized bed gasifier, thereby ensuring a more complete burning, pyrolysis and gasification of coal within the circulating fluidized bed gasifier.
