THE USE OF HEAT-RESISTANT CONCRETE AT HOT REPAIRS OF COKE OVEN BATTERIES

The article contains estimation of the well-known American and German results and developments in the use of heat-resistant concrete at hot repairs of coke oven batteries. The author describes the experience of restoring ovens availability using heat-resistant concrete according to his own method. The use of heat-resistant concrete for coke oven batteries is not common at present, due to lack of attention to this issue. Experience shows that heat-resistant concrete successfully replaces freclay part of coke oven batteries refractory brickwork. Great possibilities of replacement of coke oven batteries refractory brickwork with concrete blocks open up at improving the quality of heat-resistant con­crete on thermal conductivity and durability.More >>>

WARMING-UP AND SWITCHING OF COKE OVEN BATTERIES ON TO PERMANENT HEATING REGIME WITH PROPANE-BUTANE

The experience of the first (head) coke oven batteries heating-up without the possibility of warming-up with own coke oven or blast furnace gas at newly constructed coke and by-product plants is described. Five coke oven batteries were successfully warmed up and commissioned under the supervision of LLC “OKOS”. Unprecedented in the world practice switching of coke oven battery on to the permanent heating scheme with propane-butane gas was implemented under the supervision of LLC “OKOS”. Heating-up of coke oven batteries with propane-butane has been experimentally proved and has already been validated as reliable way of preparation for start up of the frst (head) batteries on the newly built coke oven plants and enterprises. Moreover, in actual practice, it was asserted that propane-butane can be used on the permanent heating scheme, at least for underjet coke battery.More >>>
