現今的火力發電廠及其他燃燒重油或煤炭的工廠，大多仰賴靜電集塵的方法來減少廢氣中的懸浮微粒。然而靜電集塵器的集塵效率往往會隨著使用時間的增加而降低，除了敲擊系統規律的震落積灰之外；也必須在每次工廠停工時將集塵器作較徹底的清洗，以恢復集塵效率。
假若靜電集塵器的效率隨使用時間的加長而降低得太快，為了使排放至大氣的懸浮微粒不超過新的環保標準；工廠或電廠常常得作不必要的停工維修，或者必須作運轉的降載，此兩者皆會嚴重影響它們的運轉效率。
另外，由於環保標準趨於嚴苛，目前正在使用中的靜電集塵系統勢必面臨重新改造翻新（Retrofitting）或完全更新的命運。為了避免因為排氣標準的限制而降低工廠或電廠的運轉效率，以及進一步地增進現有系統之集塵效率以符合未來更嚴苛的排放標準；本研究乃利用脈衝賦能法來開發更有效率及更省電的靜電集塵器，利用此技術將可對現有集塵器的控制設備加以改造，達到省電以及提升集塵效率之目的。

Electrostatic Precipitation（EP,or ESP）is a very effective way in removing the particulate from air streams. Thus, the EP technique has become a very popular gas cleaning method for many industrial plants which burn coals and other fossil fuels.
The performance of any EP unit will gradually decline as its service time prolong, therefore, the thoroughly clean-up on electrodes is essential during the plants’ maintenance interval. However, if the decline rate becomes too fast, the plant may have to reduce its load or completely stop its operation in order to avoid the violation of pollutant emission standard. Both the load-shredding and the irregular interruption on plant’s operation will certainly cause adverse operational efficiency and great economic impact.
More stringent emission standards in the future regulation will force the existing EP systems to either be retrofitted or replaced by a newer system. In order to improve the plant’s availability and comply with the future emission standards, the impulse energization method is theorectically and expermentally studied in this paper. The developed new technology will be used to implement the existing EP units. The modified EP system is expected to use the less operation energy and provide a much better dust-collection efficiency and with less decline rate.
