| Abstract: | Pulverized coal is ignited by a high temperature electric arc generated by a plasma generator in the pulverized coal burner. Experiments from laboratory and power plant show that the air plasma ignition technique displayed a good performance. It can enable coal-fired boilers to start, as well as to operate at low load, without or only requiring small addition of oil. Hence, the cost of power generation is reduced, environmental pollution is improved and the reliability of starting and operation at low load ... |
