The U.S. Department of Energy and ADA Environmental Solutions has 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 third reporting quarter, the electrostatic tensiometer for laboratory determination of flyash cohesivity was completed. Modifications were made to this method to improve repeatability. In addition, a new multi-cell laboratory flyash resistivity furnace was completed. Also during this quarter an agreement was reached for the initial field trial of the new additives at the City of Ames, Iowa Municipal Power Plant
