An organic-waste-processing apparatus reducing a moisture of, and conducting a thermal operation process to, an organic waste, includes: a moisture-reducing unit; a combustion unit; a combustion-energy-supply unit; an energy-supply-operation controller; an organic-waste-energy-estimating unit; a total-energy-consumption measuring unit; a relation-maintaining unit; a quantitative-relationship-grasping unit; and a moisture reduction controller. The moisture reduction controller controls an operation of the moisture-reducing unit so that the estimated value of the organic waste energy to be estimated by the organic-waste-energy-estimating unit is directed in a direction reducing a quantitative difference from the optimum value of the organic waste energy based on the quantitative relationship grasped by the quantitative-relationship-grasping unit between the optimum value of the organic waste energy and the latest estimated value of the organic waste energy.

An inside of an incinerator body into which sludge is fed is divided into a lower portion, a portion above the lower portion, and a top portion in a height direction. The lower portion serves as a pyrolysis zone for supplying fluidizing air having an air ratio of 1.1 or less together with fuel to thermally decompose the sludge while fluidizing the sludge. The portion above the lower portion serves as an over bed combustion zone for supplying only combustion air having an air ratio of 0.1 to 0.3 to form a local high temperature place to decompose NO. The top portion serves as a perfect combustion zone for perfectly combusting unburned contents. The quantity of NO generated during sludge incineration can be drastically reduced while maintaining the use quantity of auxiliary fuel at the same level as that of a conventional incineration method.
