Abstract:
Thermocouples are suspended to extend vertically and centrally of a coal reservoir to sense temperatures of coal at vertically plural points. When at least one of temperatures of coal sensed exceeds a preset temperature, a purge command signal is output by a controller to an inert gas valve.
