電蒸汽鍋爐http://www.scsuntao.cn/爐膛負壓過大，加劇了對煙管、尾部對流管壁的磨損，時間一長對流管壁會磨損減薄，且易出現(xiàn)主汽溫度偏高，發(fā)生超溫爆管等事故，對鍋爐安全運行危害更大。
　　
1、電蒸汽鍋爐爐膛負壓過大會使受熱面和爐排工況惡化；爐門、鋼架變形，爐墻裂縫。
Electric steam boiler furnace pressure over the General Assembly so that the heating surface and grate conditions deteriorate; door, steel deformation, cracks in the furnace wall.
　　
2、電蒸汽鍋爐爐膛負壓過大會加劇對流管壁的磨損，金屬管壁過熱，破壞水循環(huán)。
Electric steam boiler furnace pressure over the General Assembly increased convection wall wear, metal wall overheating, damage the water cycle.
　　
3、電蒸汽鍋爐爐膛負壓過大易使煙管脹口泄漏，蒸汽大量帶水，惡化蒸汽品質(zhì)，發(fā)生水沖擊。
Electric steam boiler furnace pressure is too easy to make big bulging mouth breathing tube leak, with a lot of water vapor, the deterioration of the quality of steam, water hammer occurs.
　　
4、電蒸汽鍋爐http://www.scsuntao.cn/爐膛負壓過大會加劇受熱面的腐蝕。
Electric steam boiler furnace pressure over the General Assembly increased heating surface corrosion.
