Biomass pellet manufacturers of Rajasthan state are currently producing the best products by making pellets of 50%-50% mustard husk and Napier grass:
Gross Calorific Value (GCV) and ash percentage for a 50-50 blend of mustard husk and Napier grass biomass pellets, we need to use weighted averages based on the proportions of the materials.
Step 1: Gather Key Parameters for Each Biomass
Here are typical values for Mustard Husk and Napier Grass:
| Material | GCV (kcal/kg) | Ash (%) |
| Mustard Husk | 3500-4000 | 6-8% |
| Napier Grass | 3800-4200 | 2-3% |
For calculation purposes, I will use average values:
- Mustard Husk GCV: 3750 kcal/kg, Ash: 7%
- Napier Grass GCV: 4000 kcal/kg, Ash: 2.5%
Step 2: Formula for GCV and Ash Percentage
To calculate the GCV and Ash for the mixture, we use weighted averages based on the 50-50 mix.
Weighted Average GCV:
GCVblend=(50/100×GCVmustard)+(50/100×GCVnapier)
Weighted Average Ash:
Ashblend=(50/100×Ashmustard)+(50100×Ashnapier)
Step 3: Perform the Calculation
GCV Calculation:
GCVblend=(50/100×3750)+(50/100×4000)
GCVblend=1875+2000=3875kcal/kg
Ash Calculation:
Ashblend=(50/100×7%)+(50/100×2.5%)
Ashblend=3.5%+1.25%=4.75%
Final Results:
- GCV of the blend: 3875 kcal/kg
- Ash content of the blend: 4.75%
This 50-50 mixture of mustard husk and Napier grass results in a GCV of around 3875 kcal/kg and an ash content of approximately 4.75%.
