2019-4-18 · To meet the legal emission standards, Ma Pan et al. designed the flue gas emission control system. In the quench tower, a NaOH solution is sprayed into the flue gas through three double-fluid atomizers to eliminate the acid gases and decrease the gas temperature rapidly from 550 to 180 °C such that the re-formation of dioxins and furans is largely avoided [16, 17].

EMISSIONS MONITORING OF BRICK KILNS EMISSIONS

proposed to fix the emission standards for PM at 250 mg/Nm3 for all kilns. It also stated that the existing kilns should comply with these new standards for PM and convert to zigzag within three years. In the intervening period, the existing brick kilns (except the down draught kilns) would be allowed to comply with the PM standard of 500 mg/Nm3.

2018-6-7 · The flue gas recirculated from the exit of the ESP is injected at approximately 23 feet above the centerline of the kiln through a separate set of blast nozzles. This injection cools the flue gas to 1350°F to eliminate the carryover of plastic or semi-molten particulate material and insures an uniform profile of flue gas entering the boiler.

2019-6-16 · Fly ash is the one of the pollutants which is emitted as SPM through flue gas. Along with fly ash un-burnt carbon is also emitted through flue gas. Due to un-burnt carbon, flue gas can be seen as black in colour. Energy efficient kiln can achieve 100 percent elimination of un-burnt carbon and can also reduce the fly ash percentage.
