  P
 roduct CRI/CSR UNIT (COKE REACTIVITY APPARATUS)
 
       
    As  per  IS 4023 : 1991  &   ASTM  :  D 5341 - 93a  
    The main equipment  consists with  furnace with  control  panel along with control system,  Cooling chamber, heater for  CO2   and post reaction test with rotating drum, reactor vessel.  
       
   

Description:

 
    Max. temperature 1300°C (without)Vessel.      Operating  temperature inside the vessel  : 1100°C Inner vessel   :   Inconal - 600G            ID – 76 mm.      Length – 900 mm.  
       
   
Items  

Insulation        : Hot  face with super  refractory  ,  back  fibre  ceramic  board    with air insulation.  

Heating Element        : Silicon  Carbide  Heating  element been  placed  horizontally  both side wall of  the  vertical mounting  inconel vessel.

Thermocouple            : R Type  (Pt – pt / RH 13%) – 2 nos.

 
       
    Furnace along with Lifting & Cooling system   :
Lifting arrangement incorporated with furnace for lifting of vessel before and after operation two no motor & gear for up and down to side movement  with automatic and  mechanical  arrangement .Cooling cabinet provided for just after vessel  lifting to be inserted vessel inside the cooling cabinet.
 
       
   

Temperature control   :  

Digital PID controller and thyristor drive unit for controlling the working temperature connected with vessel’s inner side main thermocouple.One no Digital  PID controller will control the heater temperature of  CO2 gas at 140°C after the gas cylinder towards gas panel.

 
       
   

Safety Control   : 

An independent thermocouple and in temperature controller will connected with the furnace.
 
       
   

Control Panel    :   

Consists with switch,  fuse, contractor,  stop and start switch,  Ammeter, Voltmeter,  Digital  PID temperature controller (4 nos) , indicating lamp.

 
       
    Post Reaction Apparatus   : -

One no cylindrical drum will rotate with the testing coke with a particular  speed count by counter meter.
