Communities, /Rep./ EUR , 1997, (EUR 171.5(l), pp. 189. Some coals generate a very high internal pressure during the carbonization of coals in the coke oven. Consequently.
they swell so excessively that they damage coke oven walls or cause coke pushing problems known as 'stickers'. Several methods have been employed over the years in the assessment of coal for its suitability in the production of mrtallurgical coke in the coke oven process. Examples of these methods are given. Although these tests are adequate for addressing the coking properties of coal they have failed to distinguish those coals that swell excessively during carbonization and those that do not. Therefore the problem of predicting dangerous swelling characteristics of coal using a more fundamental approach should be considered.
The aim of the present project is to establish a fundamental understanding of the relationship between the coal structure properties, the carbonization mechanism and the coke properties for coals which exhibit these properties.
