Wood pellets are the main energy pellet, by grass pellets purely being a product of the animal feed industry. On the other hand there is now a lot of research being carried out into grass fuel developments. There are quite a few reward to generating grass energy pellets, though there are also challenges in using grass as a fuel. Grass is a form of wood, biomass is simply any cellulose raw matter which can be used as an energy source. All forms of grass can be turned into pellets. However research focuses mainly on using grass species such as Switchgrass, Reed Canary Grass as well as Hemp. These grass species are seen as the most practical technique to generate grass wood fuel, as they have very high yields.

Switchgrass has a lot of interest in the US as a potential energy to be upgraded into pellets to be burnt in pellet stoves plus boilers. The idea is to promote the process of local fuel loops. Where the whole process of crop cultivation, pellet processing along with pellet distribution as well as consumption all happens within the local area. Reed canary grass is more of a cooler climate fuel crop. Both switchgrass and reed canary grass have certain combustion issues that call for to be addressed before they can be used in a pellet stove or boiler. Only certain designs of pellet burner can burn the pellets without serious complications. To learn more about suitable pellet stove along with boiler designs. Hemp is an extremely useful wood matter, it can be used for paper, clothes, rope, plastics, oil, food along with then the waste residue can be processed into hemp pellets. Hemp pellets create less incineration issues, in addition to they also make mush less ash.

Below is a video of our wood pellet boiler at PelHeat burning a selection of biomass pellets, including some Reed Canary Grass pellets. Grass pellets can generate a higher ash content than wood pellets, in addition to can also make other burning related issues. Issues such as clinker along with slag formations are common when using grass along with straw pellets. Although these features can cause issues. The savings in fuel costs can be substantial. An additional issue that much be acknowledge is the issues associated with boiler as well as stove corrosion. Pellet such as grass and straw pellets can generate high levels of chloride. Chloride is a high temperature corrosive, as well as can destroy some pellet stoves in addition to boiler in a very short time.
