Integrated low emission cleanup system for direct coal-fueled turbines (electrostatic agglomeration)
The objective of this contract is to investigate the removal of So{sub x} and particulate matter from direct coal-fired combustion gas streams at high temperature and high pressure conditions. This investigation will be accomplished through a bench-scale testing and evaluation program employing sorbent mixed with a coal-water slurry for So{sub x} removal, and an innovative particulate control concept. The particulate control device utilizes electrostatic agglomeration followed by a high efficiency mechanical collector (cyclone). The process goal is to achieve particulate collection efficiency better than that required by the 1979 new source performance standards. An additional goal is to demonstrate 70% So{sub x} removal efficiency. This research project is now in the second of a 3 phase (Phase II) project. Phase II is to fabricate the combustor and particulate control devices and install the system at a test facility located at Research-Cottrell's, KVB Western Laboratory, Santa Ana, CA. There are three functional categories, or tasks which are to be completed in sequence. These tasks are itemized as follows: Design, procurement, and installation; Shakedown and startup; Reporting. Attempts to validate the concept of electrostatic agglomeration were not possible in the shakedown program before budget constraints halted the program. What was learned was that electrostatic precipitation is feasible in the temperature range of 1600--1800{degrees}F and at pressures above 10 atmospheres.
