• To reduce the exhaustion of carbon dioxide in power plants, the operating technology for co-firing of woody biomass and coal at existing coal-fueled power plants has come to attract attention. The pretreatment of semi-carbonization and comminution before transportation can be effective in reducing the energy consumption due to transportation of biomass. The main purpose of the study is to investigate the effect of semi-carbonization on comminution energy and assessment of transport property of woody biomass. The results obtained are as follows. Empirical correlations of work index in Bond's Law are presented for both woody and semi-carbonization regions. The comminution energy can be estimated by the present empirical correlations within an accuracy of ±30 percent. From the result of analysis of energy consumptions, it is found that the total energy loss due to pyrolysis, transportation and comminution is the minimum at a mass yield condition of 0.6 for the same transport distance.
