What is Indonesian coal?
Indonesian Steam Coal is soft in texture, black & lightweight and is known for its purity, low ash, Various sizes & GAR (Gross As Received) and high thermal efficiency. The coal is available in 5200 / 5000 / 4800 GAR at Navlakhi in Gujarat. Indonesian Coal is available in 0-50 mm (Basic Size).
Does Indian coal has high ash content?
Ash content of coal produced in the country is generally 25 to 45 % whereas average ash content of imported coal varies from 10 to 20 %. Indian Coal has comparatively higher ash content than imported coal due to drift theory of formation of coal deposits in India.
How is coal GCV calculated?
The best equation has the following form: GCV= 25.284 (M) + 30.572 (Ash) + 62.127 (VM) + 138.117 (FC) – 2890.095. The result is in agree with previous work that equation involving four independent variables i.e. moisture (M), ash, volatile matter (VM) and fixed carbon (FC) provides the most accurate estimation of GCV.
