Abstract
To construct the production system of forest biomass as a small scale heating energy source, energy availability of wood-chip was examined by cost and energy balance analysis in the production process. The costs to produce wood-chip of 1 kg was calculated by yarding machines and their operational gradient conditions. As a result, 195.45~210.54 won/kg were required as production costs of wood-chip. Input energy rate (%) which is output to input energy in wood-chip production process were showed as 26.58~27.38%. Energy input rate by operational gradient was not significantly difference, and scenario B with tower yarder system appeared by more efficient than scenario A with tractor yarding system in opposition to production costs analysis.
