【Abstract】 The technique of plasma-ignition of pulverized coal, as applied in Hengyun Power Plant——the first time it being made use of in Guangdong, is being described. Pulverized coal-air flow is ignited by a high temperature electric arc, generated by a plasma generator in the pulverized coal burner, herewith enabling coal fired boilers to start, as well as to operate at low load, without or only requiring but a small addition of oil. Herewith, the cost of power generation is reduced, environmental pollution is alleviated by the electric precipitator being put in action at an earlier stage and the reliability of starting and operation at low load is warranted too.更多还原
