Dead-Man Behavior in the Blast Furnace Hearth—A Brief Review

The blast furnace campaign length is today usually restricted by the hearth life, which is strongly related to the drainage and behavior of the coke bed in the hearth, usually referred to as the dead man. Because the hearth is inaccessible and the conditions are complex, knowledge and understanding of the state of the dead man are still limited compared to other parts of the blast furnace process.

Blast Furnace Operation - an overview | ScienceDirect Topics

Internally the blast furnace is considered to consist of five discrete zones, see Fig. 17.2, through which all furnace gases and/or liquids must pass.The location, shape and extent of each zone is influenced by the properties of the material layers (relative thickness, etc.) and by the properties of the materials themselves. These factors interact to determine the flow and distribution of ...

How to Select an Exhaust Vent Screen for Your Furnace

A common mistake when adding screening to PVC furnace vents is to use ready-made PVC accessories, such as PVC termination vents, which can obstruct as much as 60 percent of the airflow. While these are fine for their intended use for blocking the end of a plumbing system vent pipe, they are not acceptable to shield the ends of furnace vents.
