C7 LIGHT EMISSION FROM SURFACE OF Spike-type  Discharge Electrode at Negative Corona Discharge in a Non-Thermal Plasma Reactor

In the past, many experimental investigations for glow or steamer corona induced plasma were conducted by digital real- time or high frame-rate charge-coupled device (CCD) cameras. In this work, the light emissions observed by the CCD camera and optical spectrometers were compared and used in numerical analysis in order to determine the effect of applied voltage as well as the geometry effect in a none thermal spike-plate plasma reactor. Normalized wavelength intensities of the second positive band of nitrogen (wave length 310 to 340 nm and normally proportional to plasma density) show a symmetrical distribution around the maximum value. In contrast, the optical emission profile of the visual spectra (wave length from 400 nm blue to 700 nm red) has bimodal distribution that was also observed by a CCD camera. Therefore, the light emission from the CCD camera is not actually representative of corona discharge or a plasma channel. Hence, all detailed investigations for any discharge plasma applications should be conducted by optical spectrometers.

C8  Use of Computer Model to Predict ESP Enhancement With the Installation of an Indigo Bi-Polar Agglomerator
Robert R. Crynack Ph.D., & Rodney J. Truce,Wallis A. Harrison

The Indigo Bi-Polar Agglomerator is a unique fine particulate control device.   Installed ahead of an existing ESP, the Agglomerator charges one half of the particles positively and one half negatively.The charged particles are mixed together, agglomerating the finer particles with the coarser ones.   A full-scale demonstration Agglomerator has been installed at Plant Watson in the USA on one-half of the 250 MW Unit #4 coal fired boiler. Testing showed a reduction in mass emissions of 45% and a reduction in stack opacity of up to 70%.   A computer model was calibrated, based on the performance of the untreated half of the ESP.   The calibrated model was then applied to the Agglomerator treated half.   After adjusting the model conditions to the flow rate for the Agglomerator side, the mean particle diameter and standard deviation were modified until the predicted emissions and opacity matched the test results.   Additionally, in-situ particle size measurements were made that confirm the increased particle size used in the model to predict the ESP performance with the Agglomerator installed.
