IN-FURNACE RETRO-REFLECTORS WITH STEERABLE TUNABLE DIODE LASER ABSORPTION SPECTROMETER

A method of monitoring combustion properties in an interior of a furnace is described. A beam of light is projected through a pitch optic including a pitch collimating lens residing outside the boiler interior. The pitch collimating lens projects the beam through a penetration into the boiler interi...

Summary:A method of monitoring combustion properties in an interior of a furnace is described. A beam of light is projected through a pitch optic including a pitch collimating lens residing outside the boiler interior. The pitch collimating lens projects the beam through a penetration into the boiler interior. The beam of light projected by the pitch collimating lens is reflected from at least one in-furnace retro-reflector, and received with a catch optic substantially identical to the pitch optic residing outside the boiler interior. The pitch optic and the catch optic may be embodied in the same pitch/catch optic. The pitch collimating lens may also be steered toward another of the at least one in-furnace retro-reflectors. Combustion properties may be calculated for each retro-reflector based on retro-reflector zones within the furnace.
