Abstract

The calorific value is the most significant factor in woody biomass utilization. We measured the calorific value by the wood parts (debarked parts and bark) and moisture content for 3 major tree species (Larix kaempferi, Pinus koraiensis, and Pinus rigida). Results showed that the calorific value decreased exponentially as the moisture content increased regardless of tree species and the wood parts. The bark had higher calorific values than woody parts (de-barked parts). In addition, Pinus koraiensis had the highest calorific values among 3 study species.
