Embodiment Construction

[0040] first reference figure 1 and 2 , showing a section 10 of a larger coke oven comprising a series or more substantially parallel side-by-side heating chambers or coke ovens 12, 14, 16 and 18, which are heated by walls 20, 22, 24, 26 and 28 apart. The base or bracket area is indicated by reference numeral 30, it being understood that the construction of the base is more complex than shown here. A top plate 32 extends across the top of the heating wall. It should also be understood that only a small portion of a coke oven is shown in the drawings for ease of understanding of the present disclosure, and only in a somewhat simplified manner.

[0041] exist figure 1 and 2 , each heating wall is shown to include a plurality of vertically oriented flues 34 in the interior of the wall. There may also be additional passages formed in the heating wall (eg horizontal flue sections, horizontal or vertical ducts, etc.), all covered by the term "flue", "vent" or "other passage". ...

Abstract

A method of repairing a refractory brick wall in a furnace that includes: (a) identifying a refractory brick wall or portion thereof that requires repair / reconstruction, pre engineering construction dimensions and accommodating various battery oven designs and oven heating systems; (b) demolishing the refractory brick wall or wall portion thereof identified in step (a); (c) installing outer reusable forms in situ, defining a new wall or portion thereof; (d) installing inner consumable forms defining one or more passageways within the new wall or portion thereof; and (e) pouring castable material into one or more areas bounded by the outer forms; (f) curing said castable material; and (g) removing the outer reuseable forms.

Description

technical field [0001] The present invention relates generally to the repair of silica brick heating walls in refractory furnaces, and more particularly, in a non-limiting and exemplary embodiment, to the repair of silica brick heating walls, roof and / or carrier arm areas in coke ovens . Background technique [0002] Typically, coke is produced in a battery of coke ovens comprising a plurality of side-by-side coking chambers or ovens separated from each other by heated walls extending the entire length of the chamber. Furnaces are sometimes referred to as "push furnaces" because the coke is pushed out of the furnace in a longitudinal direction after the coking process. A typical coke oven plant may include, for example, 30 to over 100 individual coking chambers or ovens in side-by-side relationship, each chamber being 3 to 7 meters high, typically 14 meters or longer, and about 1 / 2 to 1 meters wide. Each heating wall is typically constructed from a number of horizontally ...
