Combustion Quality of Coal and Lignite
Determination of Hard Groove
Index of Coal• Procedure:
• Take coal sample and pass it through 4.75 mm mesh
• Air dry it for 24 to 48 hours in well ventilated place
• After drying grind & Sieve it in 1.18 mm (ASTM16) and 6000micron (ASTM30 ) sieves
• At least 50% of the original sample should pass through 1.18mm sieve
• Take 50+ 0.1 grams of the sample of -1.183mm + 600micron size (passed through 1.18mm sieve and retained on 600micron sieve) in HGI instruments sample bowl

Determination of Hard Groove
Index of Coal
• Keep the 8 ball rollers of 25.400+0.003 mm dia on the sample and fix the sample bowl to the instrument
• Switch on the instrument
• The instrument will be stopped after 60+ 1 revolutions (in 3 Minutes)
• Remove the bowl from the instrument and sieve the sample through the 75 micron (IS 8) sieve
• Keep it in desiccators for 15 minutes
• Weigh the sample and its weight in M
• HGI is calculated by the formulae HGI = 13 + 6.93 × M

To determine the GROSS CALORIFIC VALUE OF coal samples using Auto
Coal Analyser
• To assess the heating value of Coal in terms of GCV to know the worth use of coal
• Procedure:
• Start the instrument and bring it to analyze mode
• Open the oxygen gas cylinder and see that the outward pressure should be 450 psi
• Calibrate the instrument with Benzoic acid pellet
• Accurately weighs 1 gram of Coal sample into crucible
• Prepare the combustion vessel as explained in the calibration procedure
• Draw 2 ltrs. Water in to the pipette from the pipette tank
• Release the water in to the bucket from the pipette by turning the stopper

Acquisition- Administrative, Social and Regulatory Mechanisms-
• Pre fire of 3 minutes and post fire 5 minutes time takes place automatically and GCV value will be displayed on the screen after 8 minutes
• Remove the combustion vessel from the bucket and expel the gases in it
• Clean and keep ready for next analysis
• Take out the bucket and transfer water back to reservoir
• Allow the analyzer to equilibrate
• Press menu and press (2) and select results
• Press menu and press (8) to enter the corrections of fuse wire, Moisture %, Ash %, nitrogen and sulphur values
• After entering the values for all the samples press menu and press (6) to get the print out of GCV values of all the samples

STRATEGIC MANAGEMENT OF ALLIANCE,MERGER AND
ACQUISITIONS
Precautions to be taken
• Fasten the wire tightly under the sleeves
• Adjust the pressure of the oxygen cylinder to fill the bomb vessel slowly
• Care should be taken while the crucible with sample to avoid spillage of the sample
• Expel the gas slowly while diffusing the bomb vessel after analysis
• Repeat the analysis if any un burnt sample is found in the crucible after analysis
• Maintain correct water level in the pipette tank
• Calibration of the instrument should be done regularly to avoid errors

Calibration procedure of GCV analyzer
• Weigh accurately one benzoic acid pellet in a crucible
• Place the crucible with in sample holder of combustion vessel and fix both ends of 10cms fuse wire in the both sleeves and arrange the wire in such a way that it is just above the sample
• Place the sample holder in the combustion vessel and close the lid tightly
• Fill the bomb with oxygen to a pressure of 450 psi (Automatically cut off)
• Fill the pipette of 2 liters capacity attached to the instrument with water from the tank
