Briquette or Pellet which is better for Biomass stove

Biomass Pellet and Briquette
The process of biomass pellet generation is different from the briquette.
Pellets used for cooking are generated after drying and compressing the biomass powder derived from wood, agricultural waste etc. Briquettes are used similar but not pulverized like biomass powder in pellet making machines as presented in the post. Hence biomass pellet is expensive compared to biomass briquette.
Advantages of Pellet over Briquette
Biomass pellet is widely used in paper mills and sugar factory. Various machines are used to produce the pellets.
For a biomass stove, pellets are generally considered to be the better option for several reasons:
Due to their uniform shape and size, they can be packed more tightly, resulting in a more efficient burn and higher heat output. This means that you will need fewer pellets to generate the same amount of heat compared to briquettes.
Pellets are manufactured under controlled conditions, ensuring consistent quality and moisture content.
This consistency leads to more reliable and predictable burning characteristics, reducing the risk of stove malfunctions or inefficient combustion.
Pellets typically produce less ash and smoke during combustion compared to briquettes.
The lower ash content means less frequent cleaning of the stove and chimney, while reduced smoke emission results in a more environmentally friendly option.
Ease of Handling and Storage
Pellets’ uniform shape and size make them easy to handle, store, and feed into the stove.
They can be easily transported in bags or stored in bulk, whereas briquettes, with their irregular shapes, might be more challenging to handle efficiently.
In many regions, especially where biomass stoves are popular, pellets tend to be more readily available compared to briquettes.
This availability ensures a steady fuel supply for your stove.
Reduced Moisture Content:
Pellets generally have lower moisture content compared to briquettes.
Lower moisture content leads to more efficient burning and less energy loss through the evaporation of excess water during combustion.
The uniformity and compactness of pellets facilitate easier ignition compared to briquettes, which might require additional effort to get them to burn efficiently.
It’s worth noting that both briquettes and pellets can be used in biomass stoves, and the best choice may vary depending on your specific situation and location.
If briquettes are more readily available or cost-effective in your area, they can still be a viable option.
However, if you have access to both and are looking for optimal performance and convenience, pellets are generally the preferred choice.
The Disadvantage of Pellet over Briquette
High Power consumption
Pelleting incurs huge electricity bills
for example, the Electricity Cost/tonne For Briquettes would be around Rs. 300/-, whereas else for pellets it could be Rs. 1000/-
High Capital cost
Production cost (labor, spared & tools, maintenance) of briquettes could be Rs. 1000/- per tonne. But for pelleting it would come to almost 2000/- per tonne.
The production capacity (Per hour) of pellets is much lesser compared to Briquettes.
Pelleting will incur huge Capital Expenditure. And working capital too, is not small. Your investment ratio of pellet: briquette Could be 3:1
Low Consumer Market
Pellet buyers are very few.
These are companies that are quality conscious and take very good care of their boilers, furnace, etc. Whereelse, briquette buyers are lot more than pellet buyers, because major industries (In India) cost concerned.
Low Moisture Required
For pelleting, the moisture should be at least below 7–8%.
High moisture biomass needs more drying cost
The dryer needs to be run day and night for moisture removal from the biomass raw materials
But the briquettes can be made from high moisture (15% -20%)
Most of the biomass from forest or agriculture waste is in the range of 15–20%.
