PROBLEM TO BE SOLVED: To suppress the production of NO while suppressing the production of NOx and the generation of a clinker by stabilizing a temperature distribution in a posterior combustion furnace disposed in disposal equipment for an organic waste.SOLUTION: A pyrolysis gas generated by the pyrolysis of an organic waste 3 is supplied to a posterior combustion furnace 16 to be burned. A temperature sensor 16a is disposed at a lower section with respect to the center along a height direction in the posterior combustion furnace 16, and a temperature sensor 16b is disposed in a high position separating from the temperature sensor 16a by a prescribed interval. The temperature sensors 16a, 16b measure a lower section temperature and an upper section temperature, respectively, in the posterior combustion furnace 16. A control section 30 calculates a temperature difference between the upper section temperature and the lower section temperature, and controls at least one of the upper section temperature and the lower section temperature so that the calculated temperature difference is kept within a prescribed temperature difference range. Preferably, the temperature difference between the upper section temperature and the lower section temperature is controlled to be constant while controlling the lower section temperature within a prescribed temperature range. |
