通過模擬結果與軟開關點焊逆變器試驗結果的對比分析，得到了如下主要結論：採用輔助網路可以完全拓寬全橋軟開關逆變器的滯后橋臂軟開關范圍，減小了次級占空比丟失，降低了逆變電阻點焊電源的開關損耗；諧振電容是影響軟開關工作狀態的重要因素，其大小不僅影響開關管的零電壓關斷，同時也影響開關管的零電壓開通范圍，因此，諧振電容應該綜合考慮；功率變壓器漏感越大，越容易滿足滯后橋臂的軟開關條件，但是大的漏感也使變壓器的通態損耗增加，降低了軟開關逆變器的效率。Abstract : the causes for low efficiency of the heater in no. 2 crude unit of jpc refinery are described and analyzed including water leaking of steam soot blower, dew point corrosion caused by steam, soot deposits in convection chamber owning to poor soot blowing, high flue gas temperature, no heat recovery of flue gas, and poor performance of insulation lining, etc. by using sonic soot removing system, flue gas recovery system, spray coating of fiber and rock wool, as well as adjustment of flow scheme accordingly in the technical revamping. the dew point corrosion is completely eliminated, the insulation performance is improved, the heat loss is reduced by 1. 25 %, the flue gas temperature is reduced to about 170, and the heater efficiency is increased from 83 % to more than 90 %
