CALDAMENTO RECUPERATIVO DI UNA BATSISTEMA DI RISCALDAMENTO PER IL RISTERIA DI FORNI DA COKE CON CANNE FUMARIE GEMELLARI

摘要

There is disclosed a heating system for regeneratively heating a coke oven battery having twin-heating flues extending side-by-side transversely of the length of the coke oven battery. Halves of the twin-heating flues are separated by a flue midfeather that forms a gas flow space at the top thereof. Between twin-heating flues, there is a heating wall midfeather extending up to the oven crown. Regenerators below the oven sole extend transversely to the coke oven battery with each regenerator coupled by three passageways to the heating flues. Two regenerators are associated with each twin-heating flue. A first passageway extends to the bottom part of one-half of one twin-heating flue, a second passageway extends to the bottom part of one-half of an adjacent twin-heating flue with these two flue halves separated by a heating wall midfeather. A third passageway extends upwardly in the heating wall midfeather where branched passageways extend into the two heating flue halves of adjacent twin-heating flues at an elevation above the oven sole.
