  • Patent number: 10696913
    Abstract: A large-scale fluidized bed biogasifier provided for gasifying biosolids. The biogasifier includes a reactor vessel with a pipe distributor and at least two fuel feed inlets for feeding biosolids into the reactor vessel at a desired fuel feed rate of more than 40 tons per day with an average of about 100 tons per day during steady-state operation of the biogasifier. A fluidized bed in the base of the reactor vessel has a cross-sectional area that is proportional to at least the targeted fuel feed rate such that the superficial velocity of gas is in the range of 0.1 m/s (0.33 ft/s) to 3 m/s (9.84 ft/s). In operation, biosolids are heated inside the fluidized bed reactor to a temperature range between 900° F. (482.2° C.) and 1600° F. (871.1° C.).
