Stave cooler with common coolant collar

A stave cooler for a furnace, comprising:

• a metal panel configured to fit between the inside of a furnace containment shell and any inner liner;
• an interior pipe circuit fully disposed within the metal panel and including at least one individual and mechanically independent loop of a pipe or a drilled passageway each with an inlet end and an outlet end for a circulating liquid coolant passed externally through the furnace containment shell;
• a metal collar with a perimeter wall attached at one end to the metal panel and extending in height away from the metal panel;
• a common through opening within the metal collar through which all inlet and outlet ends of all independent loops of pipe are enabled to pass their respective parts of the circulating liquid coolant externally through the furnace containment shell;
• the metal panel substantially comprises a single copper casting;
• the interior pipe circuit is cast within the metal panel as a pipe or a drilled passageway;
• the one end of the metal collar attached to the metal panel is attached by casting and embedding it inside the metal panel;
• the metal collar substantially comprises carb n steel and numbers no more than one per metal panel;
• and
• the metal collar provides substantially all support necessary for the weight and gas sealing of the stave cooler when mounted within and through a matching single penetration of the furnace containment shell;
• wherein, process gas sealing failures of conventional stave are eliminated.

A stave cooler, comprising

• a main body panel of cast copper in which are fully disposed a number of loops of cooling pipes each loop having an inlet end and an outlet end, and all of which inlet and outlet ends are turned up together in a single grouping;
• a hollow steel support collar with opposite openings and attached at one such opening to the main body panel of cast copper such that the single grouping of inlet and outlet ends is fully surrounded and accessible for external coolant plant connections through a second such opening;
• wherein a single such hollow steel support collar is sufficient to support the entire weight of the stave cooler inside a furnace shell through a one-per-stave penetration of the furnace shell and that thereby makes the single grouping of inlet and outlet ends externally accessible for coolant plant connections that can pass through the second such opening;
• wherein the single grouping of inlet and outlet ends is shielded from supporting the weight of the stave cooler and are thereby less susceptible to cracking and water leaks.
