It is used in coal geological exploration, coal quality evaluation and coal utilization. Widely used, the grading standard is for how to more scientifically evaluate the ash, sulfur, calorific value, etc. in coal resources, and rationally use coal Resources have important guiding significance and are composed of three parts. ---Part 1.Ash content. ---Part 2.Sulfur. ---Part 3.Heat. During the application process of GB/T 15224.2, due to the changes in supply and demand in the coal market and the advancement of high-sulfur coal application technology, the judgment of high-sulfur coal The decision is prone to disputes, and in the process of coal geological exploration and quality supervision, disagreements are prone to appear. According to the actual use of the standard, some Standards are adjusted and clarified. Coal quality classification Part 2.Sulfur content1 ScopeThis document specifies the classification of coal according to the range of dry-based sulfur content (St, d) and the inspection of coal sulfur content.
