Abstract

A study of the thermal effects observed during the low-temperature pyrolysis of various types of pelletized biomass (sunflower husk, coniferous wood, litter-litter mass) is presented. It is shown that during sunflower husk torrefaction the greatest exothermic effect is observed and the possible reasons for its occurrence are explained. The influence of a small oxygen content in the heating medium on the exothermic effects during biomass torrefaction is analyzed. It has been suggested that the use of internal energy resources of the process (waste heat of exhaust gases and internal energy released in the process of biomass torrefaction) significantly increases the torrefaction process energy efficiency and allows to consider secondary biomass as a real competitor to traditional fuels, a substitute for fossil coal.

生物质烘焙过程中的热效应

摘要

提出了对各种类型的颗粒状生物质（葵花皮，针叶木材，垃圾凋落物）进行低温热解过程中观察到的热效应的研究。结果表明，在向日葵壳烘烤过程中，观察到最大的放热效应，并解释了其发生的可能原因。分析了加热介质中少量氧气对生物质干法烘烤过程中放热效应的影响。有人提出，利用过程中的内部能源（废气余热和生物质烘焙过程中释放的内部能量）可以显着提高烘焙过程的能源效率，并可以将次级生物质视为传统竞争的真正竞争者。燃料，替代化石煤。
