Technical specifications for solid biofuels por Belbo, Helmer

“…Net calorific value is highly demanded by both producers and consumers and should be obligatory information for most kinds of solid biofuels. Content of heavy metals and Cesium 137 should be stated if it is high enough to cause risk for restrictions regarding ash recycling in crop land and forest. …”
