Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
144 words
A device for evaporative cooling of metallurgical furnaces, particularly blast furnaces, comprising banks of vertically arranged members to be cooled that accommodate pipes for passing the coolant, external pipes that connect the pipes of one cooling member of a bank with the pipes of another cooling member of the same bank, headers adapted to supply the coolant to, and discharge it from, said cooling members, said headers forming together with the external pipes and the pipes of the cooling members a vertical circulation circuit, the number of the discharge and supply headers being equal to the number of the pipes in one cooling member, each row of verTically connected pipes in each bank being coupled to one of said supply headers and one of said discharge headers which are common to similarly arranged rows of pipes in the other banks of the cooled members.
Claim 2
Independent Claim
144 words
A device for evaporative cooling of metallurgical furnaces, particularly blast furnaces, comprising banks of vertically arranged members to be cooled that accommodate pipes for passing the coolant, external pipes that connect the pipes of one cooling member of a bank with the pipes of another cooling member of the same bank, headers adapted to supply the coolant to, and discharge it from, said cooling members, said headers forming together with the external pipes and the pipes of the cooling members a vertical circulation circuit, the number of the discharge and supply headers being equal to the number of the pipes in one cooling member, each row of verTically connected pipes in each bank being coupled to one of said supply headers and one of said discharge headers which are common to similarly arranged rows of pipes in the other banks of the cooled members.
Claim 3
Dependent Claim
34 words
A device as claimed in claim 1, wherein even and odd rows of pipes in each bank of cooled members are combined in pairs and each pair of rows is coupled to individual headers.
