Abstract: This paper introduces the basic concepts of fluid mixing and a new gas-gas mixer with a cone-shaped distribution section researched and developed according to the mixing requirements of flue gas and purified flue gas during the development of activated coke dry flue gas desulfurization technology. Compared with the existing tee-type mixer, the speed and temperature distribution in the new gas-gas mixer is more uniform, which can effectively prevent the low temperature zone and avoid dew point corrosion during the gas mixing process. Meanwhile, this can also improve the mixing efficiency, but the pressure drop may increase slightly.

Key words: high-efficiency, gas mixing, dew point corrosion, flue gas
