Bioenergy

This Technical Guide provides guidance on the conversion of existing coal fired boilers to wood pellet operation. There are a number of obvious advantages to using wood pellets: they are 100% renewable and relatively clean burning. Of paramount importance in a conversion is the need both to maintain the safety and integrity of the boiler and control systems, and also to improve safety to the level of best practice.

Forestry and wood processing residues are a potentially significant source of bio-energy fuels. For a variety of reasons storage of these materials prior to utilisation is often necessary. The storage of comminuted (chipped, hogged, shredded or reduced to small particle size by other means (sawing or sanding)) biomass, particularly fresh (green) material such as logging residues can lead to degradation of the fuel due to biological and thermo-chemical processes.
