Abstract

PURPOSE: To remove NOx at a low cost by incinerating the non-composting materials separated before and after a fermentation stage for waste and reducing the NOx in the gas of said incineration by using the ammonia formed by fermentation.
CONSTITUTION: Waste is supplied to a high speed composting plant 1, where it is subjected to middle temp. fermentation then to high temp. fermentation in a fermentation stage. In the middle temp. fermentation, CO2 is generated and in the high temp. fermentation, CO2 and NH3 are generated, by which compost is formed. Before or after the fermentation stage, the non-composting materials which are not suited for composting or are infeasible to compost are separated as the residues of screening, and these are conducted from the plant 1 to a fluidized bed incineration furnace 2, where they are incinerated. The waste gas of fermentation contg. NH3 is kept introduced from the fermentation stage into the furnace 2 and the NOx in said waste gas is reduced by NH3.
