等离子点火机理及其应用

为了减少电厂锅炉点火和稳燃用油消耗量，最终达到无油点火，采用与传统不同的新工艺，该新工艺既可提高燃烧过程的经济性，又可以改善火电厂的生态条件。丰城电厂1-4号炉自采用新工艺DLZ-200型等离子点火系统以来，节约了大量的燃油，实现了少油点火和低负荷下无油稳燃，为当前各电厂进行燃油系统改造、实现锅炉无油点火或低负荷稳燃提供了较好的经验。

Mechanism of Plasma Ignition and Its Application

With the worldwide lack of the energy,the price of the petroleum is contin ually increasing.In order to decrease the power plant oil wastage on unit start -up and keeping the flame stable with part load to perform oil -free sta rt -up at end,the Model DLZ -200Plasma Ignition System(MDPIS),a new technology which is much more d ifferent from traditional technique should be applied.It can n ot only make the burning process more economical but also improve the ecologic condition of the power plant.FengCheng power plant have saved much fuel -oil and performed few -oil ignition a nd kept the flame stable with part load on oil-free condition since the MDPIS appl ied.This successful experience has provided valuable reference for other power p lants on the alteration of oil -syste m,the performame of oil -free start -up and on keeping the flame stable with part lo ad.
