Ash preparation

Ash pellets

In the process of making pellets the ash is mixed with water and, if carbon content is high (>10%) Åbyhammar, et al., 1994, additives with a gluing effect. The mixture is then pressed through a strainer forming oblong cylinders. This method is less expensive than making granules. Furthermore, pellet production is less sensitive for variations in ash heterogeneity.
