Characteristic Study of Coal-firing Unit Plasma Firing

Abstract: This topic main research plasma ignition technology's application and the present moves the existence question, the coordinated ion ignition principle, the movement mechanism have carried on the multianalysis, take the present Lingwu power plant two 600,000 kilowatt air cooled units as main object of study, real-time track power plant normal and under unusual operating mode movement condition, to each time suspends shipment, the starting time plasma fired state to carry on the computation, the analysis, then has conducted the research to the existence question, proposed that solves the question method. Regarding enhanced the boiler to start the efficiency, the energy conservation aspect put forward the proposal, to its efficient beneficial supplement.The plasma burner is takes the ignition source ignition powdered coal using the plasma electric arc, is one kind highly effective, the stable boiler starts the ignition way, the use plasma ignition technology may reduce when greatly the unit start the oil used…
