What is the thermal conductivity of furnace brick?

The thermal conductivity of furnace bricks can vary depending on the specific type and composition of the brick. However, generally speaking, furnace bricks are designed to have relatively low thermal conductivity in order to provide effective insulation and minimize heat loss.

The thermal conductivity of furnace bricks typically ranges from 0.5 to 1.5 W/m·K (Watts per meter Kelvin). This means that for every 1-meter thickness of brick, there would be a heat transfer of 0.5 to 1.5 Watts for every Kelvin temperature difference across the brick.

It's important to note that different types of furnace bricks may have varying thermal conductivities due to differences in materials and manufacturing processes. For example, insulating fire bricks (IFBs) have higher porosity and lower density, resulting in lower thermal conductivity compared to dense fire bricks.

To obtain more precise information about the thermal conductivity of a specific furnace brick, it is recommended to refer to the manufacturer's specifications or consult technical data sheets provided by the manufacturer.
