电蒸汽锅炉http://www.jnshengxin.cn/炉膛负压过大，加剧了对烟管、尾部对流管壁的磨损，时间一长对流管壁会磨损减薄，且易出现主汽温度偏高，发生超温爆管等事故，对锅炉安全运行危害更大。
1、电蒸汽锅炉炉膛负压过大会使受热面和炉排工况恶化；炉门、钢架变形，炉墙裂缝。
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、电蒸汽锅炉炉膛负压过大会加剧对流管壁的磨损，金属管壁过热，破坏水循环。
Electric steam boiler furnace pressure over the General Assembly increased convection wall wear, metal wall overheating, damage the water cycle.
3、电蒸汽锅炉炉膛负压过大易使烟管胀口泄漏，蒸汽大量带水，恶化蒸汽品质，发生水冲击。
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.
