Corrosion of heating furnace chimneys
Thread Content
Figure 1 shows that, due to the fact that during the operational process the flue gas temperature remained within the range of the low-temperature dew point, the carbon steel chimney suffered corrosion and perforation after more than 2 years of use; Figure 2 depicts the condition of the chimney after repair. The lesson to be learned from this incident is that for metal equipment in flue gas systems, it is essential to avoid the flue gas dew point, which can prevent metal corrosion.
The chimney corrosion incident tells us that metal components in flue gas systems should be prevented from operating at the dew point temperature for extended periods to avoid metal corrosion. .
May I ask what the temperature of the exhaust smoke is, and which device is it?
