Abstract:
1. A method of reducing heat radiation losses through coke oven chamber doors and end walls, comprising: pressing a heap of coal by applying a compacting method to obtain a compacted coal cake having a density ranging from 700 to 1300 kg/m charging the compacted coal cake through the charging opening of a coke oven chamber into the coke oven chamber; wherein the height and/or density of the coal cake next to the coke oven chamber doors and end walls is modified by one of: (a) generating a recess within the coal cake during coal compaction at the upper coal cake sides to be placed facing the coke oven chamber doors, by omitting an amount of coal in the coal cake, the recess being formed by: (b) generating an elevation within the coal cake during coal compaction at the upper coal cake sides to be placed facing the coke oven chamber doors, by adding an amount of coal to the coal cake.
