電蒸汽鍋爐http://yangchuncity.com/爐膛負(fù)壓過(guò)大,加劇了對(duì)煙管、尾部對(duì)流管壁的磨損,時(shí)間一長(zhǎng)對(duì)流管壁會(huì)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(duì)鍋爐安全運(yùn)行危害更大。
1、電蒸汽鍋爐爐膛負(fù)壓過(guò)大會(huì)使受熱面和爐排工況惡化;爐門(mén)、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(fù)壓過(guò)大會(huì)加劇對(duì)流管壁的磨損,金屬管壁過(guò)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(fù)壓過(guò)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.
