【 摘 要 】

The U.S. Department of Energy and ADA Environmental Solutions have begun a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the flyash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During the second reporting quarter for this project, design and development is continuing on an electrostatic tensiometer to measure cohesion of flyash layers. A dedicated test fixture to automate flyash electrical resistivity testing is also underway. Ancillary instrumentation to control gas humidification within these test fixtures is also under construction.
