In-duct humidification system development for the LIMB demonstration project
- Babcock and Wilcox Co., Alliance, OH (USA)
Two keys to an operable humidification system are the atomizer design and the atomizer arrangement within the duct. The atomizer must produce a spray of extremely small droplets in order to achieve complete evaporation in the short residence times available in most ducts. The atomizers must also be installed in such a way as to prevent droplet impingement on the duct walls, minimize the ash deposition on the atomizer tip, and maximize the mixing between the spray and flue gas. Good mixing is essential to maximize SO{sub 2} removal and to ensure complete evaporation. A full-scale demonstration of LIMB technology will be conducted on the 105 MW, Unit 4 Boiler at Ohio Edison's Edgewater Station in Lorain, Ohio. This paper presents the results of a project to develop a humidification system for the full-scale demonstration.
