电除尘脉冲供电技术在350MW机组中应用

Application of Pulse Energization in the Electrostatic Precipitations of the 350MW Power Plant

文章简介了电除尘器脉冲供电技术原理与特点,以及其在350MW燃煤发电机组的电除尘器的直流供电改造试验情况。结果表明,改造后电除尘器的除尘效率明显提高,其出口浓度比原直流供电的降低56.30%,脉冲供电能无故障运行,效果好,安全可靠,可大幅节约电能。

In this paper,the principle and characteristics of the pulse engergization for electrostatic precipitations(ESP) was introduced simply,and application experiment of pulse energization in the ESP of the 350MW power plant was described.It is concluded from applications that derating of dust concentration at exit with pulsing are 56.30% in contrast to d.c.power supplies,under identical gas factors.Applications demonstrate that pulse source operate without difficulty,have high efficiency,good safety and reliability,and greatly safe energy.
