【 摘 要 】
The fabrication drawings for the Advanced ElectroCore module and the water-cooled precharger were completed during this reporting period. The drawings were sent to four fabrication shops as part of a bid package. Of the three companies that chose to participate, the contract to fabricate the two components was awarded to Advanced Fabrication Services of Lemoyne, PA on 3 November 2000. Fabrication began the following week. The components are scheduled to be completed in mid to late January 2001. The design of the dry scrubber was delayed while the problem of low dew point spread in the exhaust stream was resolved. The temperature of the exhaust gas from the outlet of the existing ESP is only 260 F. Some of the sorbents to be tested are liquid and therefore, the amount of sorbent that can be added before the exhaust gas reaches the due point is limited. The solution was to use a combustor to burn LPG and mix the two exhaust streams to get the desired temperature. Calculations indicated that burning LPG at the rate of 500,000 Btu/hr would be sufficient to raise the gas temperature to 400 F.
