Abstract

An apparatus and method for non-intrusive collection of
off-gas data in a steelmaking furnace includes structure and
steps for transmitting a laser beam through the off-gas
produced by a steelmaking furnace, for controlling the
transmitting to repeatedly scan the laser beam through a
plurality of wavelengths in its tuning range, and for detecting
the laser beam transmitted through the off-gas and
converting the detected laser beam to an electrical signal.
The electrical signal is processed to determine characteristics
of the off-gas that are used to analyze and/or control the
steelmaking process.
