Thermal Conductivity Of Fire Clay Brick

Date:2016-02-15 09:51 | From:Zhengzhou Sunrise Refractory | Author:admin
Thermal conductivity is defined as the quantity of heat that will flow through a unit area in direction normal to the surface area in a defined time with a known temperature gradient under steady state conditions. It indicates general heat flow characteristics of the refractory and depends upon the chemical and mineralogical compositions as well as the application temperature.
 
High thermal conductivity refractories are required for some applications where good heat transfer is essential such as coke oven walls, regenerators, muffles and water cooled furnace walls. However, refractories with lower thermal conductivity are preferred in industrial applications, as they help in conserving heat energy.
 
Porosity is a significant factor in heat flow through refractories. The thermal conductivity of a refractory decreases on increasing its porosity.
 
Although it is one of the least important properties as far as service performance is concerned, it evidently determines the thickness of brick work.
