steam emission
A conduit, chimney, cooling tower, or other facility releasing water vapor from a heating process into the atmosphere.
A steam emission conduit, chimney, cooling tower, or other facility is an object through which water vapors from any heating process are released into the atmosphere.
The emitted material is water vapor arising from a heating process. A chimney is one possible structure rather than the only permitted form.
Smoke emission concerns gases resulting from combustion. A visible plume alone does not determine which process a facility serves.
