80年代初,上海杨浦煤气厂一台SGS-30/13一I型燃油水管锅炉,突然发生爆管,三小时内锅内水全部漏光,造成脱水事故,被迫紧急停炉,并将事故情况及时地报告了有关部门。我们在对该锅炉进行检查时发现:爆管前,蒸汽压力为6.8kgf/cm~2,(0.667MPa)额定压力为13kgf/cm~2(1.28MPa),蒸发量约17T/h,额定蒸发量为3 0T/h,水冷壁管径φ=42×2.5mm,爆管位置,在炉膛左侧第三根 At the beginning of 1980s, a SGS-30/13-I type oil-water boiler in Shanghai Yangpu Gas Plant suddenly burst pipe and leaked water inside the pan within three hours, resulting in dehydration accident, forced to shut down the furnace and accident situation Timely report to the relevant departments. During the inspection of the boiler, we found that the steam pressure was 6.8kgf / cm ~ 2, the rated pressure was 13kgf / cm ~ 2 (1.28MPa) and the evaporation was about 17T / h before the squib. The rated evaporation The amount of 3 0T / h, water wall diameter φ = 42 × 2.5mm, squib position, the third left in the hearth
