Description
Summary:A technique has been developed which is capable of giving reliable measurements of temperature response at the centre of large wet coal particles during heating in an inert convective heating environment. This technique utilises a water-cooled probe to insulate the thermocouple from the surrounding environment, and multiple particles are attached to the end of the thermocouple to ensure even heating of the thermocouple in this region. These precautions are found to limit the rate of thermal conduction along the thermocouple, which has been shown to have a considerable effect on the measured temperature. This technique has also been shown to provide reasonable measurements for the temperature response of wet coal particles in a fluidised-bed, and for dry coal particles in the convective flow environment.
