为了研究在低变质程度下储存的褐煤煤质的变化规律,以确定褐煤在煤场最佳存放条件,对宏伟热电厂燃用的大雁、宝日褐煤进行试验,试验结果是各煤层中心点温度最低、粒度变小、收到基低位发热量降低、煤量月损失率为0.54%。建议定期监测煤堆温度,堆煤过程中充分压实,褐煤在库存允许条件下储存时间不宜超过15天。
In order to study the variation law of lignite coal stored at a low degree of metamorphism and to determine the optimal storage conditions of lignite in the coal yard, experiments were carried out on the Dayan and Baoru lignites burned at Grand Thermal Power Plant. The result of the experiment is that the temperature of each coal seam center is the lowest , Smaller particle size, received base low heat, coal loss rate of 0.54% monthly. It is recommended to regularly monitor the temperature of the coal pile and to fully compaction during the coal accumulation process. The lignite should not be stored for more than 15 days under the conditions of the inventory.
