The report gives results of an evaluation of Advanced Electrostatic Augmentation of Fabric Filtration (ESFF) on a slipstream from a stoker-fired boiler. Advanced ESFF, with its characteristic high-voltage center-wire electrode, was compared with conventional filter bags in the same baghouse using calibrated flow orifices. The advantage of advanced ESFF was demonstrated by consistently higher gas flow rates in the bags with the corona producing electrodes. Analysis of the data showed that the specific resistance of an electrostatically enhanced filter was 70% less than that of a conventional bag. An economic analysis showed a capital cost savings of 26% with advanced ESFF based on doubling the air/cloth ratio for advanced ESFF. In a second test, the feasibility of using top-inlet filtration on stoker fly ash was established. No definitive comparison with conventional bottom-inlet filtration could be made in the allotted test period.
