The MFS/1 is an oven specifically designed to determine the moisture content of coal. MFS stands for Minimum Free Space, referring to the oven’s miniature chamber that adheres to standards for drying coal.
The established coal mass is inserted into the chamber at a temperature between 105°C and 110°C under a flow of Nitrogen ISO model or Air ASTM model until the mass remains constant. The difference in mass after the heating process determines the moisture content.
There are two models: MFS/1/ISO meets the standards BS 1016-104.2:1991, BS ISO 687:2010, and BS ISO 11722:2013, and MFS/1 ASTM complies with ASTM D3173-11.
MFS ovens have a volume of 1.4 litres, an exact chamber size of H 25 x W 195 x D 290 mm, and a height reduced to 22 mm directly below the thermocouple. The maximum operating temperature is 210°C, with uniformity and stability maintained within a tolerance of ±0.5 °C.
The MFS/1 ISO uses Nitrogen to remove coal moisture, which is supplied by a regulated bottle. S/1 ASTM operates with a regulated flow of air.
