Abstract
A method of heat conditioning a coke oven in a battery circulates hot gas through the oven from a non-radiant burner.
Claims4
In an operating battery of coke ovens in which at least a substantially common portion of more than three successive walls separating adjacent ovens of a group in the battery are unheated at least for a time sufficient that the unheated walls defining at least one oven of the group reach ambient temperature, a method of heat conditioning the unheated walls of the group of coke ovens, comprising:
- at least temporarily enclosing at least substantially so much of each oven of the group as is delimited by facing unheated walls;
- injecting into the each oven a flow of hot gas from a non-radiant burner at a velocity sufficient to circulate the hot gas therethroughout;
- and
- controlling the temperature of the hot gas such that the walls thereabout are heated without differential thermal expansion damage.
In a battery of coke ovens in which at least a portion of one wall of one oven is unheated at least for a time sufficient that it reaches substantially ambient temperature and the opposite wall is warm, at least one end of the oven being open, a method of heat conditioning the unheated wall, comprising:
- at least temporarily enclosing at least so much of the one oven as is delimited by the ambient-temperature wall portion;
- from a time sufficiently close to the completion of the at least temporary enclosure that the temperature of the warm wall has not significantly affected the temperature of the ambient-temperature wall-portion, injecting into the oven a flow of hot gas from a non-radiant burner at a velocity sufficient to circulate the hot gas therethroughout;
- and
- controlling the temperature of the hot gas such that the walls thereabout are heated without differential thermal expansion damage.
