以催化裂化油浆作热源的蒸汽发生器,油浆走管程,壳程发生蒸汽。以前在停工检修时,由于降温减油不能发生蒸汽则先停脱氧水.当停油浆用蒸汽吹扫油线和发生器管程时,管程残存的油浆就从小浮头或漏了的管子漏入壳程。结果管程吹净了,而不该清扫的壳程却漏入了油浆,也被迫进行清扫,基本年年如此,浪费了人力和物力。1983年5月停工检修时,采取壳程停水后,接 Catalytic cracking slurry as a heat source steam generator, slurry go tube, shell side steam. Previous stoppage overhaul, due to the cooling oil can not steam stop the first deoxygenated water.When the stop slurry with steam purge oil line and the generator tube, the tube residual slurry from small floating or missing tube Leak into the shell. As a result, the pipe was blown clean, and the shell-side, which should not be swept away, leaked into the slurry and was forced to clean. This has been so year after year that human and material resources were wasted. May 1983 stop work overhaul, take shell-side water, then
