The fully-automatic RSC inert control unit was supplied as an intelligent interface between the gas analyser system and the CO2 inerting system. The RSC controls all parameters of the gas analyser system, coal mill temperature sensors, CO2 inerting system, valves and flaps of the entire coal grinding process.
Coal Mill Inertization. an inerting system decreases the probability of combustion of flammable materials stored in a confined space, especially a fuel tank, by maintaining a chemically non-reactive or "inert" gas, such as nitrogen,1 in such a spaceinerted" fuel tanks may be used on land, or aboard ships2 or aircraft.
Application Example: A coal pulverizer - when it is started and coal is added, there is a point when the suspended coal particles and the air are in the explosive range. The same condition exists on shut down as coal is removed. CO2 can make this start up and shut down safe by inerting the air/coal mixture and preventing an explosive atmosphere.
