Abstract

An orifice plate for improving particle distribution within a coal piping system includes a plate body defining a central orifice therethrough bounded by an inner periphery of the plate body. The plate body is configured and adapted to be affixed between end flanges of adjacent pipes in a coal piping system so as to generally align the central orifice with an internal flow passage through the coal piping system. Flow disruption features are defined in the inner periphery of the plate body. The flow disruption features are configured and adapted to disrupt a flow of air and particles flowing through the central orifice to provide a more uniform distribution of particles downstream of the plate body than upstream.

Abstract

A method for controlling dosage of a reagent in a selective catalytic reduction (SCR) system includes the step of providing the system with a plurality of reagent injection nozzles, each nozzle being configured and adapted to be independently calibrated during an SCR reaction when the system is in operation. The method further includes determining an influence coefficient for each injection nozzle for a catalyst independently of the other injection nozzles, and optimizing the flow of reagent from each injection nozzle to minimize a sum of deviation across a surface of the catalyst. A system performs selective catalytic reduction (SCR) and a machine readable medium contains program instructions to controlling dosage of a reagent in a selective catalytic reduction (SCR) system.

Abstract

The invention provides a system for converting urea into reactants useful for removing N0씟 from industrial emissions. The system includes a urea inlet, a steam inlet, and a reactor in fluid communication with the urea inlet and the steam inlet The reactor is configured and adapted to inject urea from the urea inlet into a steam flow from the steam inlet to convert the urea into at least one reactant for N0씟 reduction within a substantially gaseous mixture. The invention also provides a method of converting urea into reactants for reducing N0씟 out of industrial emissions. The method includes injecting urea into a steam flow to convert the urea into at least one reactant for N0씟 reduction within a substantially gaseous mixture.

Abstract

This invention relates generally to the treatment of NOx in combustion flue gas. In certain embodiments, the invention relates to the use of a regenerative heat exchanger (RHE) to convert urea to ammonia in a side stream of flue gas. Ammonia and/or other urea decomposition products exit the heat exchanger,- are mixed with the rest of the flue gas, and enter a selective catalytic reduction (SCR) unit for reduction of NOx in the flue gas. The use o an RHE significantly improves the thermal efficiency of the overall process. More particularly in certain embodiments, the regenerative heat exchanger is a dual chamber RHE.
