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.
