  • biomass especially plant-derived biomass can effectively utilize carbon resources converted from carbon dioxide by photosynthesis during the plant growth process, so even if it is burned as fuel, carbon dioxide in the atmosphere can be seen in terms of the overall carbon dioxide balance. Will not be increased (carbon neutral).
  • biomass compared to coal, biomass has features such as high water content, low density, low calorific value, low pulverizability, high hydrophilicity, high biodegradability, and high alkali content, making it difficult to use directly, and it is also difficult to transport and transport. There are also problems with storage and handling.
  • One of the conventional techniques for solving these problems is semi-carbonization treatment and consolidation molding as biomass pretreatment methods.
  • Semi-carbonization treatment can be expected to have effects such as imparting hydrophobicity, lowering water content, lowering biodegradability, and improving pulverizability, in addition to improving the energy density per mass of biomass.
  • by improving the crushability it is possible that the use of existing crushers in coal-fired power plants and a high co-firing rate can be achieved at the same time.
  • the upper limit is a co-firing rate of 2 to 3 cal%, but wood semi-carbonized pellets (wood chips).
