Coal tar quality

The main factors affecting the quality changes of coal tar include the quality of raw coal, the operating conditions of the coke oven, the coal mixture ratio, and the design technology of the coke oven. The type of raw coal, its particle size distribution, and its composition directly affect the formation of coal tar. Coke oven operating conditions such as oven temperature, coal packing density, and coking time all affect the yield and quality of tar. The coal mixture, particularly the selection and proportion of different coal types, determines the chemical composition of tar. The advancement of coke oven design technology, such as the size of the coke oven, the material used for its construction, and its thermal efficiency, are also important factors that determine the quality of coal tar. As coke ovens become larger, the adjustments to the corresponding technical and operational parameters also have an impact on the properties of coal tar. .

The most important factor affecting coal tar is the type of coal, with lignite, bituminous coal, and anthracite being the main distinctions. Another important influencing factor is the coking process and operating conditions. The original poster had better study the basic textbooks on coal coking. Additionally, when coal is coked, it is necessary to mix different types of coal in order to produce coke of the desired quality; the composition of this mixture also affects the quality of coal tar.
