Relationship Between The Hole Diameter of Checkers in The Regenerative Chamber of Top Combustion Hot Blast Stove and Heat Exchange Capability

摘要

This research has been carried out through top combustion type experimental stoves simulated at hot state.The capability of heat exchange for two kinds of checkers with different hole diameter have been compared.The results shows that checkers with hole diameter of 20mm have higher capability of heat exchange than that of checkers with hole diameter of 30mm,which is attributed to its more heat exchange area,small heat conduction thickness and big heat exchange coefficient.
