Abstract
There is need to increase the portion of forest biomass in effective power plants. However, it must be done safely: examples of superheater damages exist. Maximum energy portion of wood biomass in its blends with different peats (and with one coal) was calculated with two indexes: molar S/Cl and molar (2S + Al) / Cl ratios. These indexes are based on the ability of sulphur (as So3) and aluminium silicates to destroy corrosive alkali chlorides in the power plant furnace before their entering to superheaters. It is possible to co-fire forest biomass at 50-90 % energy portion with peats. These results must be implemented carefully because for example calcium can weaken the power of sulphur and more research work would be needed to know better the importance of Ca.
