| 20130074482 | EXTRACTION OF HOT GAS FOR REAGENT VAPORIZATION AND OTHER HEATED GAS SYSTEMS - A method to extract hot exhaust gas from the exhaust flue and use its heat energy to vaporize aqueous reactive reagents such as aqueous ammonia or to provide a heated air process gas mixture. Compressed air provides motive force to induce a vacuum in an ejector venturi device which draws hot exhaust gas (“hot gas”) from the exhaust flue. In one embodiment the hot gas is drawn into a vaporizer unit. The heat energy in the hot gas vaporizes the injected aqueous reagent. The vaporized mixture is drawn into the ejector and is entrained in the motive air. The diluted reagent vapor mixture is injected back into the exhaust flue to support the selective catalytic reduction (SCR) process and reduce nitrogen oxide (NOx). | 03-28-2013 |
