A latent heat-ballasted gasifier suitable for converting biomass, coal, or low-quality fuels into a producer gas. Latent heat is stored in the reactor in ballasts containing a metal alloy with a melting point approximate the pyrolysis temperatures of the fuel. A fluidized bed reactor is used to enhance heat transfer between the latent heat material and the fuel. The latent heat-ballasts allows the reactor to be operated in a quasi-steady mode rather than a batch operation employed in the prior designs.

[ What is claimed is:] [1.] A method for storing heat comprising the steps of:providing a vessel having a) a fluidization chamber in the vessel, b) a plurality of ballast housings arranged in the fluidization chamber to permit dispersion of heat therebetween, the ballast housings containing a solid material with a melting point at a predetermined temperature, c) a particulate material in the fluidization chamber, and d) an exhaust port in fluid communication with the vessel;introducing heat into the fluidization chamber; andmelting said solid material;heat energy evolved from the material in the ballasts during a transition from a liquid state to a solid state being capable of providing heat at least into said fluidization chamber.
