Programme Overview
The concept of coal pulverization stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The raw coal is fed into the pulverizer along with heated air. As the coal gets crushed, the hot air dries it and blows the usable fine coal powder out, which thereafter is transported to coal bunker for storage or directly for use in blast furnace. The exhaust air is then purified by a bag filter.

Critical Control of Process Gas
A mix of fine coal powder and hot carrying air is inevitably creating carbon monoxide(CO). For the purpose of safety operation requests a continuous monitoring of oxygen(O2) and trace carbon monoxide(CO) in each process of coal pulverization, transfer and storage.

FPI's Solution
High-speed response (down to 1s) of the LGA analyzer highlights its reliability for safety control. The non-contact laser and sensor of the in-situ LGA combined with continuous purge results in virtually maintenance free.
