一、概述 空气等离子焰点火是在发电厂锅炉上取代常规的燃油点火的一种新方法,是一项节油的新技术。空气等离子焰具有很高的能量,其中的活化氧粒子对煤粉具有强烈的氧化性,在同煤粉混合的过程中能迅速地传递能量,并瞬间点燃煤粉。据美国马里塔电厂介绍,用这种方法点火可比常规方法点火减少5/6的点火能量,潍坊电厂采用这种方法减少点火能量7/8。 铀矿开采研究所与山东电力所、潍坊电厂协作,于1981年9月在75吨/时烟煤锅炉上实现空气等离子焰点火,一次点火可节油2.2吨,1982年7月又应用于莱芜
First, an overview of the air plasma flame ignition is a new method to replace the conventional fuel ignition on the power plant boiler is a new fuel-efficient technology. Air plasma flame has a high energy, of which the activated oxygen particles have a strong oxidative power of pulverized coal in the process of mixing with the powder can quickly transfer energy and instant ignition of pulverized coal. According to the introduction of the United States Marita Power Plant, ignition by this method can reduce the ignition energy by 5/6 compared with the conventional method, and the Weifang Power Plant adopts this method to reduce the ignition energy by 7/8. Uranium Mining Research Institute and Shandong Electric Power, Weifang Power Plant in September 1981 in 75 tons / hour bituminous coal-fired boilers to achieve air plasma flame ignition, an ignition can save 2.2 tons, in July 1982 and applied to Laiwu
