Description:
The report gives results of a laboratory test demonstrating the feasibility of electrostatic precipitation at high temperatures (to 1366 K) and pressures (to 3550 kPa): corona currents were stable at all temperatures. Detailed current/voltage characteristics under negative and positive polarity were obtained in dry air, in a simulated combustion gas, and in a substitute fuel gas for each temperature and pressure level. Major effects of temperature, pressure, and electrode geometry on precipitator design characteristics (sparking voltages, corona starting voltages, and current levels) were evaluated. This work has established that no practical temperature or pressure limitation exists to the levels tested. A preliminary cost estimate is presented for a commercial-size precipitator design applied to a commercial fluidized-bed combustor and turbine system.
