Abstract
Selective non-catalytic reduction (SNCR) of pollutant remissions in a fossil fuel combustion furnace having water cannons installed therein for removing combustion incrustation is accomplished by using the water cannons intended for de-slagging by mixing a reagent with water and administering the mixture under high velocity and high blast flow rate to the interior of the furnace for reduction of pollutant emissions, such as NOx, with the water cannons. The water cannons may be switched from the SNCR function to a de-slagging function.
Claims16
The method of selective non-catalytic reduction (SNCR) of pollutant emissions in a fossil fuel combustion furnace having water cannons installed for removing combustion encrustation, comprising;
- mixing a reagent with water and administering said mixture under high velocity and high blast flow rate to the interior of said furnace for reduction of pollutant emissions with said water cannons.
An apparatus for selective non-catalytic reduction (SNCR) of pollutant emissions in fossil fuel combustion effluent, comprising;
- a fossil fuel combustion furnace having articulatable water cannons installed for removing combustion encrustation in said furnace, said water cannons connected to a source of a de-slagging compound under high pressure for injection by said water cannons into said furnace;
- said water cannons also alternatively connected to a mixture of reagent and water under high pressure whereby selected of said water cannons may be switched form a de-slagging function to an SNCR function.
