Abstract

A description and details of performance are given for a differential thermal apparatus which has been developed at the C.S.I.R.O. Division of Coal Research for use in studies of the mineral matter in coal. An important feature of the design is the block assembly unit, which fits into a vertical furnace, and comprises a stainless steel block in which are the three sample wells and three insulated chromel-alumel thermocouples. The output from the differential thermocouples is applied to a simple transistorized D.C. amplifier before being passed to a recorder which traces simultaneously against time the temperature difference and the temperature. Features of the apparatus which have proved especially attractive in research on coal are its automatic operation, ease of maintenance, and base-line stability. Reproducibility of results is good.
