Description:
The report gives results of a successful Charged Droplet Scrubber (CDS) pilot demonstration of coke oven emissions control. It also describes the design, installation, and checkout of the demonstration system. The CDS uses electrically sprayed water droplets, accelerated through an electric field, to remove particulate material from a gas stream. The pilot demonstration was a continuation of laboratory and bench scale studies for application of the CDS to fine particle control. The pilot demonstration included, in addition to the CDS, the ducting, flow transitions, and blower necessary to circulate process gas through the CDS. The test was performed at the Kaiser Steel Company coke oven facility, Fontana, California. A large fraction of the coke oven emissions were submicron and composed of carbon particles and hydrocarbon aerosol. After the system checkout was completed, during which CDS operating parameters were established, the demonstration test series was performed. Results of the demonstration test indicate that the CDS is an effective pollution control device for controlling coke oven stack emissions.
