| 
| Two features of the RSD are thermocouple in the sample and flexible sample chamber. These features allow the RSD to be used in a flow of gas; eg air or oxygen. The screw top sample containers is easily modified with a gas inlet and interior metal gauze to allow for gas flow through a powder or liquid.
It is simple within the RSD configuration to set up a gas flow system where the gas (passing through a metal coil prior to entering the sample cell) will be preheated to the sample cell temperature. In addition, with a restriction and a T-piece on the gas exit, it is possible to get gas flow at an elevated pressure and to simultaneously measure pressure.
The results reported here are for simple oxidation and ignition temperature delumination of a coal sample.
Tests have been carried out in air and pure oxygen. |
