Fire detection in carbon silos

Oxygen and carbon powder are injected into an electric arc furnace to produce a frothy layer of slag. The combustion of CO creates CO₂. It provides additional energy for the smelting process. The coal for this process is stored in silos. When a coal silo is not in use, the use of oxygen measurement technology makes it possible to detect the fire risk based on the increase in oxygen content in the silo. Alternatively, a GM901 in-situ gas analyzer can detect the fire risk based on the increase in CO content in the silo. A combination of these two fire detection methods is also possible.
