Dynamic control of selective non-catalytic reduction system for combustion of urban solid waste based on semi-continuously fed loader

摘要

A SNCR method (300; 400; 500; 600) for controlling an amount of a NOx reducing reagent in urban waste combustors, the method (300; 400; 500; 600) comprising the steps of: providing an oven (700 ) which has a grid (750) for waste (710); measure in real time (310; 410) oven temperature changes; use (320; 420) measured oven temperature changes to predict changes in oven NOx levels in real time; and use (330; 430) the predicted changes in oven NOx levels to dynamically adjust the amount of NOx reducing reagent
