Advantages and Disadvantages of Densification

Briquettes are primarily used instead of firewood for manually charged domestic stoves. Pellets can be used in automatically charged stoves and boilers due to their good flowability, uniform water content, grain size and chemical composition. Consequently, pellet stoves and boilers for domestic applications offer a comfortable operation similar to oil fired systems. This post aims to talk about the advantages and disadvantages of densification.

The main advantages of fuel densification compared with not densified fuels are as follows: Increased bulk density after the densification, which reduces transport costs, reduces the need for very large storage spaces, and simplified the handling of the fuel. Increased energy density and more homogeneous composition provide better options for burning, and therefore a more efficiency combustion process.

The main disadvantage of densification is the relatively high cost of input energy, which is needed for the production of pellets and briquettes. This will also increase the price of the output product. The output product is in the form of briquettes or pellets. Calorific value, water content and chemical composition are approximately same for both, but the density and strength is usually higher for pellets. The main difference is in size. Pellets are 4-5times longer than their diameter, while briquettes have a diameter of 80-90mm. Briquettes and pellets provide a simple use in the fully automatic operation from home use to large scale applications.
