Making Wood Pellets

Making wood pellets is a growing industry all around the world, for both developed and developing countries. In developed countries making wood pellets for the purposes of wood pellet fuel, animal bedding and BBQ wood pellets. In developing countries making wood pellets mainly for the use as a cooking fuel in none powdered gasification stoves. In developing countries the damage of deforestation is a growing problem. Through pellets, the use of waste wood residue and particularly waste agricultural residue such as straw can be upgraded into pellets. Using pellets in the cooking stoves produces far more heat, and gets to temperature much more quickly. It also takes much less wood to cook food, and this can play a crucial role in reducing deforestation as populations continue to increase.

Wood Pellet Press

A wood pellet press is the key piece of equipment used in making wood pellets. There is a choice between either a flat die pellet press or a ring die pellet press, each design has its own advantages and disadvantages which are explained in the guide. Both designs work on the principle of compression through a die with a set of rollers creating the pressure. Both designs have different configurations of either the die rotating with stationary rollers, or the rollers rotating with a stationary die. During the pellet making process, intensive forces act on the wood to raise the temperature to around one hundred degrees Celsius. At this temperature the wood becomes gelatinised, and then the rollers compress the wood in the die.

Burning Wood Pellets

Below is a video of our wood pellet boiler here at PelHeat. Depending on the wood resource used, the burning characteristics of the wood pellets change. For example some pellet boilers can only burn premium pellets, where other boilers such at the Tatano in the video, can efficiently burn wood pellets which produce a much higher ash content. This boiler can also burn a wide selection of other biomass fuel pellets including straw and grass pellets, miscanthus pellets and even cardboard pellets. Some biomass fuels can create issues in clinker and slag formations, and high corrosion risks, this is why choosing the right pellet boiler is crucial for true fuel flexibility.
