Coal cake density
Thread Content
How can the density of the compacted coal ready for furnace use be measured? Do anyone have any good suggestions?
It seems similar to the bulk density method used for coal testing.
Here, I first form coal briquettes, then insert a steel pipe into the briquettes and afterward pull the pipe out to weigh it (the volume and weight of the steel pipe are calculated in advance)
I found a cylindrical iron tank at the scene, with a bottom but no lid; I measured its inner diameter and depth, and weighed it. When the coal bin was almost full, it was placed inside; after compacting the coal, the iron tank was taken out and the total weight of the tank plus the coal was measured. The density of the coal cake was calculated based on the definition of density. I wonder if it’s feasible? Since the rammer cannot reach the coal inside the tank, it’s not clear whether this is representative

It is difficult to measure accurately because there is a density difference between the top and bottom of the coal cake! It is best to use a weighing device to determine the weight of the coal cake after compaction, and then divide that by its volume!
