越来越多的电厂开始采用等离子煤粉点火燃烧器,等离子煤粉点火燃烧器采用直流空气等离子体作为点火源,可点燃挥发分较低的(10%)贫煤,实现锅炉的冷态启动而不用一滴油。文章结合近期内蒙古准大发电厂等离子点火装置的投运情况、等离子点火装置投运情况下影响煤粉着火的主要因素进行了分析。 More and more power plants have begun to use plasma ignition of pulverized coal, plasma-fired pulverized-coal burners use direct-current air plasma as an ignition source, and can ignite lean coal with a lower volatile content (10%) to achieve a cold start of the boiler Without a drop of oil. Combining with the recent operation of the plasma ignition device in Zhundao Power Plant in Inner Mongolia and the main factors affecting the ignition of the coal powder during the operation of the plasma ignition device,
