Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
110 words
A device for the evaporative cooling of metallurgical furnaces, particularly blast furnaces, comprising horizontal rows of aligned members to be cooled, the members of the horizontal rows being aligned to provide vertical rows, vertical pipes for passing a coolant accommodated by each member, external pipes connecting the pipes of the cooling members of one horizontal row with the vertical pipes of the cooling members vertically aligned therewith in the horizontal row thereabove, the cross section of said external pipes and the vertical pipes of the members in the higher horizontal rows being greater than the cross section of the external pipes and the vertical pipes in the lower horizontal rows.
Claim 2
Independent Claim
110 words
A device for the evaporative cooling of metallurgical furnaces, particularly blast furnaces, comprising horizontal rows of aligned members to be cooled, the members of the horizontal rows being aligned to provide vertical rows, vertical pipes for passing a coolant accommodated by each member, external pipes connecting the pipes of the cooling members of one horizontal row with the vertical pipes of the cooling members vertically aligned therewith in the horizontal row thereabove, the cross section of said external pipes and the vertical pipes of the members in the higher horizontal rows being greater than the cross section of the external pipes and the vertical pipes in the lower horizontal rows.
Claim 3
Dependent Claim
58 words
The evaporative cooling device as claimed in claim 1, including a reservoir for the coolant, delivery conduits between the reservoir and the vertical pipes of each member of the lowermost horizontal row, discharge conduits leading from the vertical pipes of each member of the uppermost horizontal row to the reservoir, and control valve means for the delivery conduits.
