The ZoloBOSS™ makes use of tunable diode laser absorption spectroscopy, (TDLAS) measurements, laser multiplexing capabilities, and tomographic algorithms to generate two-dimensional maps of boiler conditions including temperature, O₂, CO, CO₂, and H₂O concentrations, simultaneously, anywhere in the combustion region or in the back-pass of the boiler. Installation is simple and requires only a 2 1/2" access ports for each pair of measurement heads.

Measurement is possible with only a beam of light, so there are no sensor tips to wear out or replace - no reference gases are required, and no probe heating necessary. The system does not need calibration, and does not drift.

There are four essential system components. An overview showing the control rack and a typical measurement layout is shown below. The control rack, located in the control room, generates detects and processes observed laser signals. The Matrix Distribution Cabinet (not shown), mounted near the boiler, switches the laser signal from path to path. Node boxes (not shown) are mounted on each measurement level and house electronics. Send and receive heads are mounted on customer supplied flanges directly on the boiler, and align to each other at all times to deliver and receive laser through the boiler.
