摘要

将农林业生物质废弃物与煤炭进行混燃发电是一种可同时提高环境和经济效益的能源利用方式。本文以稻壳为研究对象

以10℃/min的升温速率在热重实验台上进行了稻壳分别与1种烟煤和1种褐煤的混燃实验。通过热重研究和动力学分析发现:稻壳的掺入可以改善烟煤着火和燃尽等燃烧特性

且改善效果在一定范围内随着稻壳掺混比例的增大而更佳;但稻壳与褐煤的混燃并未显著影响褐煤的燃烧特性;将稻壳与煤进行混燃利用时

应根据煤种及掺混比例的不同具体考虑其混燃特性。

Abstract

Co-combustion of agriculture and forest residues with pulverized coal provides a promising way to generate power more environmentally-friendly and economically.In this paper

rice husk was co-combusted with a bituminous coal and a lignite respectively.A non-isothermal thermogravimetric method was adopted to investigate the combustion characteristics of various coal/biomass blends at heating rate of 10 ℃/min from 100 ℃ to 1 000 ℃.The results show that

the addition of rice husk improved the bituminous coal combustion

and this effect seemed to be enhanced by increasing the proportion of rice husk.In contrast

no significant interactions were observed in combustion of lignite/rice husk blends.Therefore

in the actual cocombustion of rice husk with coal

the combustion performance should be evaluated based on the type of the coal used.
