A Burning Issue Indeed.
There was, maybe still is, debate between CIL & NTPC over the cost grades using GCV against the suggested UHV. An in-grade UHV tolerance of 840kcal has been mentioned as acceptable. Where exactly are the Kalimantan samples taken? Results are normally only available after the ship sails. Is there a chance that high moisture, not unknown in Indonesian coal, has percolated into the lower holds and played havoc with the unloaded sample?
You might consider passing this topic onto your puchasing department so they can appraise their overall shipping performance. ■
Standards for GCV Drop in Steam Coal
Respected Seniors and my dear friends,
We are facing a problem of tremendous drop in GCV of Steam Coal which we are recieveing from Indonesia.
It has been noticed that average drop of 400 - 500 Kcal/Kg in the GCV of every Vessel we are recieving when measured at Load Port and the GCV when measured after recieveing the coal at our stockyard (India).
I request seniors to please enlighten the facts about GCV drop ratio and whether any standard exists to calculate the GCV drop?
It will be very helpfull for me to calculate the actual drop in GCV. ■
