<p>PURPOSE:To provide a trash incineration furnace with a NOx removal system which can ensure an NOX removal reaction space between a denitration agent and combustion exhaust gas without increasing the capacity of a vacant air tower part, and perform an NOx removal process without newly adding denitration agent injecting air. CONSTITUTION:A trash incineration furnace 2, input chute 1 to feed trash in the trash incineration furnace 2, supply pipes 8, 10 to supply secondary and tertiary air to a vacant tower part on the top of the incineration furnace, device to mix/make accompany a denitration agent in a denitration agent tank 18 in the secondary, tertiary air by flow gauges 28, 29 and control valves 30, 35, flame sensor 36 which are provided in stages in the vertical direction in the vacant tower, and a device to control a mixing quantity of the denitration agent in response to the increase/decrease of a flame extension and flame capacity being detected by the flame sensor, or in response to a trash supply quantity to be input in the furnace are provided.</p> |
