科林炉停车概述

Overview of Colin Furnace Parking

粉煤气化炉停车过程中涉及到的步序和注意事项繁多,不同炉型之间的停车步序也各不相同且不同操作人员的操作手法也存在差异,这使得气化炉整个停车过程存在优化空间。介绍科林气化炉停车过程中减负荷、退气、烧嘴停车、保压置换,降温和泄压等主要步骤和注意事项,在保障整个系统负荷、压力稳定和操作安全的前提下,通过操作人员在各个环节的人为干预,有效减少了气化炉停车过程中对前、后系统造成的波动,加快了停车置换、降温所需的时间,为气化炉停车检修进度节约了时间成本,也为气化炉下次开车投料时的工况稳定奠定了基础。

There are many steps and precautions involved in the shutdown process of a powder coal gasification furnace.The shutdown steps vary among different furnace types,and the operating techniques of different operators also vary.This leaves room for optimization in the entire shutdown process of the gasification furnace.This article introduces the main steps and precautions during the shutdown process of the Colin gasifier,including load reduction,gas withdrawal,burner shutdown,pressure replacement,cooling,and pressure relief.Under the premise of ensuring the stability of the entire system load,pressure,and operational safety,human intervention by operators in various stages has effectively reduced the fluctuations caused by the front and rear systems during the shutdown process of the gasifier,and accelerated the time required for shutdown replacement and cooling.This has saved time and cost for the shutdown and maintenance progress of the gasifier,and also laid the foundation for stable working conditions during the next start-up and feeding of the gasifier.
