Installation for determination of coke strength after reaction with carbon dioxide (CSR and CRI).

The machine is designed for testing coke according to GOST R 50921 (ISO 18894) "Coke.
Determination of reactivity (CRI) and coke strength after reaction (CSR)" (Edition with
Amendment). The facility allows the determination of coke reactivity (CRI) values
to carbon dioxide and coke strength after reaction with carbon dioxide.
(CSR).
The facility simulates the chemical, thermal and physical factors leading to the
coke breakdown in a blast furnace and evaluate the changes that occur to the coke. The method
consists in the reaction of coke with carbon dioxide at a temperature of 1100°C, determination of the mass of the
of the coke residue after the reaction, mechanical treatment of this residue in a drum at room temperature and subsequent sieving.
temperature and subsequent sieving. At the same time, control of the heating temperature regime,
gas supply mode (CO2 and N2), drum rotation speed are controlled automatically
by the control unit according to the standard and the preset programme.
