PROBE FOR CONTROL OF TEMPERATURE MODE OF COAL PILE

摘要

A probe for control of temperature mode of a coal pile includes a sharpened and sealed at the lower end steel tube inner cavity of which is restricted at the upper end of the tube with a plug, temperature sensor. From partially filled with heat carrier inner cavity of the tube air is removed, and it is sealed. A device for filling and sealing is used as a plug. The temperature sensor is installed outside of the tube at its upper end. The upper end of the tube above the coal pile is covered with heat-insulation material.
