Installation for determination of volumetric yield of volatile substances.

The installation for determination of volumetric yield of volatile substances is intended for
test according to GOST 7303 "Anthracite. Method for determination of volumetric yield of volatile substances
Volatile substances" and allows you to determine the yield of volatile substances in anthracite and products of thermal processing of fuels.
fuels thermal processing products. The unit allows testing samples in which the yield of volatile substances is less than 8 per cent.
of volatile substances is less than 8 per cent.
The unit allows to determine the volume of released volatile substances by the volume of
liquid displaced from the aspirator when heating the fuel sample without access to air at
temperature (900±10)°C for 15 min.
The unit consists of a tubular vertical electric furnace and a regulator for maintaining a constant temperature in the working zone of the furnace.
