Patent ID: 7712306

Claim:
A system for controlling emission levels of NO x in a selective non-catalytic reduction (SNCR) system comprising: a. a furnace for receiving an amount of waste, said furnace containing a flue and a grate for moving the waste through the furnace; b. a continuous emissions monitoring (CEM) system comprising: i. a probe for determining composition of pollutants, NO x levels, or levels of un-reacted reagents emitted by the furnace; ii. a link to the SNCR system for providing information on the pollutants, NO x levels, or un-reacted reagents contained in the emissions from the furnace; c. an SNCR controller having programmable logic stored on computer readable media for causing the SNCR system to perform the step of distributing a reagent to one or more locations in the furnace which have reached a specified temperature; and d. a combustion controller for controlling and monitoring the amount of waste introduced into the furnace.
