印尼煤堆存时间与热值变化的研究

Study on the Change of Storage Time and Calorific Value of Indonesia Coal

摘要: 煤炭露天堆放导致煤质下降，影响锅炉机组运行。本文研究了印尼煤在南方煤场自然露天条件下堆存时间与热值变化试验的内容和方法，分析了在不同条件下、不同堆存深度热值损失变化规律，并针对试验研究结果提出了印尼煤科学堆存时间及防止热值损失建议，为燃煤电厂合理采购、调运印尼煤及其堆存管理提出了有效的措施。

Abstract: Piling coal in the open air leads to the decline of coal quality and affects the operation of boiler units. This article studies on the contents and methods of the storage time and calorific value change test of Indonesian coal under the natural open pit conditions of the southern coal yard, analyses the variation law of calorific value loss under different conditions and different storage depths, and puts forward the scientific storage time of Indonesian coal and the suggestions for preventing calorific value loss in view of the experimental results. Effective measures have been put forward for rational purchase, transportation and storage management of Indonesian coal in coal-fired power plants.
