P-3-12　Techno-economic assessment of heat sources in a base drying system for fuel chips for wood gasification CHP

Abstract

Among decentralised small-scale biomass energy sources with potential to revitalise local communities, combined heat and power (CHP) from gasification is promising in terms of its high power-generation efficiency, but it has not yet achieved stable operation, partly due to the variation in the moisture content of the wood chips that are used as fuel. This study reports on the techno-economic evaluation of a system using CHP, a wood chip-fired boiler and an organic Rankine cycle as heat sources, based on the assumption that a centre capable of efficiently producing high-quality dry chips is to be set up in a sawmill.
