资料简介

在过去5年中,对torrefaction技术的兴趣显著增加。 作为固体生物质预处理技术。这种兴趣主要是被驱使的。 通过生物质焦化和致密化的特点包括更好 煤的运输特性和配伍性,如加热 值、可磨性、体积能量密度和疏水性。各种各样的 最有可能考虑用于烘干和致密生物质的应用 其中包括在煤粉发电厂和水泥中与煤共燃。 窑炉、焦炭和钢铁工业(用于焦化生物质),中小型专用 生物质和颗粒燃烧器,以及在正常情况下的夹带流气化器中的气化 操作煤粉。

The last 5 years has seen significant increase of interest in torrefaction technologies as a pretreatment technology for solid biomass. This interest has mainly been driven by the characteristics of the torrefied and densified biomass including better transportation characteristics and compatible properties to coal such as heating value, grindability, bulk energy density, and hydrophobicity. Among the various applications being considered for the torrefied & densified biomass, the most likely ones include co-firing with coal in pulverised coal fired power plants and cement kilns, coke and steel industry (for charred biomass), small to medium scale dedicated biomass and pellet burners, and gasification in entrained flow gasifiers that normally operate on pulverized coal.
