Controlling the humidity of cupola blast air.
With the installation of a dehumidifier, U.S. Foundry lowered coke consumption requirements for a more cost-effective cupola operation.
The operation of a foundry cupola can be influenced by the weather; specifically, the ambient relative humidity can have a substantial effect on several performance measures. If the moisture content of the air entering the cupola is high, the operation is adversely affected, whereas on a dry day, when the air entering the cupola is low in moisture, beneficial effects can be noted. In many regions, operation the cupola is much more uniform during the winter, when humidity is generally low, compared to the summer season, when the moisture content of the air var...See the full content of this document
