We describe the ignition and control of a flash fire at elevated pressure (≈1 MPa) within a packed bed of biomass. The fire moves upward through the bed, against the downward flow of air, triggering the transformation of biomass into gas at elevated pressure, and charcoal with fixedcarbon yields that reach the thermochemical equilibrium “limit” in
