A gasifier (10) for particulate combustible material in effect separates the pyrolysis and the oxidation of the flowable fuel material with a traveling grate (40) for advancing a bed of the material from a material feed station (40A) to a material discharge station (40B). A material feed mechanism (60) has fuel and ember chutes (62, 64) for depositing hot embers below combustible material. Discharge transport apparatus 70 separates ash from combustible residue, i.e., embers. A recirculation transport (80) delivers combustible residue to the ember chute (64) where it is reintroduced to the traveling grate (40) for a further transit through the gasifier (10).
