“…The phenomena of Corona discharge are composed of a cumulative ionization process. Production of these ions extracts energy from the transmission supply and thus contribute to net electrical losses [25]. Factors that affect corona losses are atmosphere, conductor size, and spacing between conductors and line voltage.…”

The goal of the research is to develop a methodology to minimize the public's exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective is achieved by combining EPA Screen3, ISC3 and Japanese METI-LIS model equations with minimum spanning tree (MST) algorithm. Prim's MST algorithm is used to simulate an electric distribution system and coal transportation pathways. The model can detect emission interaction with another source and estimate the ground level concentrations of emissions up to distances of 25 kilometers. During a grid search, the algorithm helps determine a candidate location, for a new coal power plant, that would minimize the operational cost while ensuring emission exposure is below the EPA/NIOSH thresholds. The proposed methodology has been coded in form of a location analysis simulation. An exhaustive search strategy delivers a final candidate location for a new coal power plant to ensure minimum operational costs as compared to the random or greedy search strategy. The simulation provides a tool to industrial zone planners, environmental engineers, and stakeholders in coal-based power generation. Using operational and emissions perspectives, the tool helps ascertain a list of compromise locations for a new coal power plant facility.

“…Ozone production especially intended to water treatment is probably one of the main industrial application of corona discharges in competition with chlorine-based techniques [11,12]. Corona discharge can be unwanted such as in high voltage lines where it leads to non negligible power losses [13] or in printing devices generating ozone that can be harmful to human health [14,15] as well as for the material due to the high oxidizing potential of this molecule. Last but not least, ozone is a greenhouse gas that contributes to the climate change.…”

The spatial and temporal evolution of the ozone density has been measured in a 1 cm electrode gap tip to plane positive pulsed corona discharge in air at atmospheric pressure with no gas flow. It was expected to observe a higher ozone density in the vicinity of the discharge gap but ozone has been found at a quasi uniform density level up to 10 cm from the electrode gap after only 30 s of ignition. Such a wide distribution of ozone in the reactor cell is attributed to strong turbulence mostly triggered by the ionic wind. The mapping of the ozone density associated to the power measurement led to the estimation of the ozone production yield in term of mass per electrical energy.
