What is the calorific value of Indonesian coal?
Based on the calorie level, Indonesian coal is low calorie coal (<5100 cal/gram) 32.64 billion tons, medium calorie (5100-6100 cal/gram) 82.26 billion tons, high calorie (6100-7100 cal/gram) 8.27 billion tons and very high calories (> 7100 cal/gram) 2.11 billion tons.
What is the GCV of coal?
|GCV BAND (K.Cal./Kg.)||GRADE|
|Exceeding 6700 and not exceeding 7000||G-2|
|Exceeding 6400 and not exceeding 6700||G-3|
|Exceeding 6100 and not exceeding 6400||G-4|
How do you calculate coal GCV?
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.
Does Indian coal has high ash content?
Indian Coal has comparatively higher ash content than imported coal due to drift theory of formation of coal deposits in India. Coal seams formed due to drift theory contains higher ash as compared to in-situ theory of formation.
What is Indonesian coal used for?
Indonesian Coal is available in 0-50 mm (Basic Size). This variety of coal is typically used in Power Plants, Paper Mills, Chemicals & Dyes Industries, Process Houses, Coal Screening Plants, Gasifier Plants and other industries.
How is Coke different from coal?
Coal is a lustrous, black fossil fuel that includes impurities, generates smoke, and generates less heat than coke when burned. Coke is a dingy, black coal waste that burns hotter and cleaner. … Coke is a fuel made from mineral coal that has been calcined or dry distilled.
How do you calculate coal?
Mining Coal Calculations
- AD factor (converts AD to Nominated Moisture (NM)): (100-NM)/(100-ADM) NM = AD / ((100-NM)/(100-ADM))
- Dry factor (converts AD to Dry) (100-ADM)/100. Dry = AD / ((100-ADM)/100)
- AR factor (converts Dry to AR): (100-TM)/100. …
- DAF factor (converts Dry to DAF): (100-Dry Ash)/100.
What is the cost of coal per kg?
Prices of Grade 6 coal, with GCV between 5,500 and 5,800 Kcal per Kg, were increased 10.3% from Rs 1,450 per tonne to Rs 1,600 per tonne. The lower grade coal is primarily used by power generation companies.
What is the meaning of RB2 coal?
globalCOAL’s RB1 grade reflects the standard grade of South African export coal with a calorific value of 6,000kc/kg. globalCOAL’s RB2 specification, which rarely trades on the spot market, is for a higher level of volatile materials. … Coal that meets RB1 specification is easily tradeable in Europe.
