A new concept in particulate control, called an advanced hybrid particulate collector (AHPC), is being developed at the Energy& Environmental Research Center (EERC) under U.S. Department of Energy (DOE) funding. The AHPC combines the best features of electrostatic precipitators (ESPS) and baghouses in a manner that has not been done before. The AHPC concept combines filtration and electrostatics in the same box, providing major synergism between the two collection methods, both in the particulate collection step and in transfer of dust to the hopper. The AHPC provides ultrahigh collection efficiency, overcoming the problem of excessive fine-particle emissions with conventional ESPS and solves the problem of reentrainment and recollection of dust in conventional baghouses. The objective of the project is to develop a highly reliable AHPC that can provide >99.99% particulate collection efficiency for particle sizes from 0.01 to 50 μm, is applicable for use with all U.S. coals, and is cost-competitive with existing technologies.
