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:

MaterialGCV (kcal/kg)Ash (%)
Mustard Husk3500-40006-8%
Napier Grass3800-42002-3%

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%.
