EXPERIMENTAL AND MODELING STUDY OF THE EFFECT OF H2 CO and CH4 ON THE THERMAL DeNOz PROCESS
IntroductionNitrogen oxides (NOx) are one of the most hazardous pollutants in the air. Reducing Nox emissions has been required by implementation of stringent clean air regulations. Thermal DeNOx is a well-known Nox control process by injecting NH3 agent into combustion products containing NO at proper temperature1. A serious limitation of this processes is that the temperature range over which the agents are effective is relatively narrow. In boilers operating with varying load or in many existing boilers where space for injection NH3 is not available in this temperature range, reduction at lower temperature is often desirable2. Researches have indicated that addition of small amounts of selected additives3-7 to the injected NH3 make it possible to decrease the optimum reduction temperature. H2, CO and CH4 are the most common gas additives for thermal DeNOx process. Different experimental studies have indicated that all of them could shift the temperature window to lower temperatures. However few researches identify the difference of these additives.
