Abstract

The thermal decomposition of the mixtures of crushed coal and wood was experimentally studied in a temperature range from 400 to 1000°C. According to the results of the experiments, the possibility of using wood as an additive to mixed fuel based on coal to decrease the yield of sulfur oxides upon combustion in large- and small-scale power boilers was confirmed. With a decrease in the energy characteristics (calorific value) of these mixed fuels by no more than 9%, as compared with widely used homogeneous grade T coal, the environmental parameters were significantly improved on the combustion of a mixture of coal and wood. It was found that a significant synergistic effect on the sequestration of sulfur oxides was achieved during the formation of calcium and aluminum sulfates in the ash of mixed fuel due to the joint thermal decomposition of coal and wood particles at a wood fraction from 10 to 50% in the mixture.

煤与分散木混合料燃烧时抑制氧化热解产物中硫氧化物的机理

摘要

在400至1000°C的温度范围内，对碎煤和木材混合物的热分解进行了实验研究。根据实验结果，证实了使用木材作为基于煤的混合燃料的添加剂以降低在大型和小型动力锅炉中燃烧时硫氧化物的产率的可能性。与广泛使用的均质T级煤相比，这些混合燃料的能量特性（热值）降低不超过9％，因此，在燃烧煤炭和木材的混合物时，环境参数得到了显着改善。
