Abstract
Provided is an oxidation equipment for oxidizing a raw material containing at least one of carbonized coal and a torrefied biomass, the oxidation equipment including: a main body unit forming a fluidized bed; a gas supply unit supplying an oxygen-containing gas so that the raw material flows; a gas discharge unit discharging gas which has passed through the fluidized bed; a cooling unit cooling an oxidized product obtained by oxidizing the raw material; and a delivery unit delivering the oxidized product from the cooling unit, in which the main body unit has a first pressure measurement unit in a freeboard portion and a second pressure measurement unit in a portion through which the fluidized bed passes, and the delivery unit has a delivery amount control unit that controls the delivery amount of the oxidized product based on a differential pressure of the first and second pressure measurement units.
