Storage time of washed coking coal
Thread Content
I would like to ask marine professionals: how long can washed coking coal be stored outdoors before it oxidizes and deteriorates?
It generally does not exceed 3 months, and it is stored properly
It is determined by the degree of metamorphism of the washed coking coal; coal with a lower degree of metamorphism has a higher gas porosity, absorbs more oxygen, and is thus more prone to oxidation. The storage time for coal supplied by Ansteel is as follows: it varies depending on the quarter: Quarter 1, 2, 3, 4 – Bituminous coal: 60, 50, 50, 60; Rich coal: 80, 70, 70, 80; Coking coal: 100, 90, 90, 100; Lean coal: 100, 90, 90, 100
