Title:
DENITRATION EQUIPMENT AND REDUCTANT DISTRIBUTION ADJUSTMENT METHOD FOR DENITRATION EQUIPMENT
Document Type and Number:
Japanese Patent JP2016155102
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress local concentration increase of unreacted reductant on the outlet side of a denitration reactor.SOLUTION: Denitration equipment comprises: a plurality of reductant injection nozzles; an injection amount adjusting part for adjusting an injection amount of reductant from each reductant injection nozzle; a denitration reactor which is disposed downstream of the reductant injection nozzles and is configured so as to decompose nitrogen oxides by reaction between nitrogen oxides in exhaust gas and the reductant; a distribution measuring part for measuring a second distribution of the reactant in a second surface vertical to a flow direction of the exhaust gas on the outlet side of the denitration reactor; and an instruction producing part for producing an operation instruction for the injection amount adjusting part based on: the injection amount of the reductant of each of the plurality of reductant injection nozzles; a correlation of a first distribution of the reactant in a first surface vertical to a flow direction when the reductant injected with the injection amount arrives at the inlet side of the denitration reactor; and the second distribution measured by the distribution measuring part.SELECTED DRAWING: Figure 1
