Is nitrogen or steam better for purging the furnace chamber of a heating furnace?

I think nitrogen is good; it’s a pure gas with no side effects!

However, steam purging allows gases to be seen from the chimney, while nitrogen cannot be seen；；

The steam is great! Nitrogen cannot blow away coke formation on the furnace walls and similar deposits

Steam is used for furnace purging; after purging with nitrogen, it is necessary to replace it with air, otherwise ignition will not be possible.

Generally, blowing with nitrogen for a few minutes is sufficient; steam is basically useless!

If it’s a large square furnace, simply open the flue damper! Use nitrogen for small furnaces as well
