Abstract

The project deals with the insulation of a heater inside which the air is being circulated at 18000C and whose outer shell is maintained at a temperature of less than 1000c. There are only limited materials available which can bear such high temperatures. Though some materials are available, they possess high densities say, corundum mulliete which has higher temperature resistance but has high density. To compensate this, we use the material by making it in the shape of honeycomb. Different related studies reveal that honeycomb has more temperature drop than normal solid material. Other materials such as microsil, cera blanket, SA-516 are been used whose thermal properties are flexible for insulation. The modelling and numerical analysis work has been carried out using various tools such as Creo 4.0, ANSYS 17.0, ICEM etc., and to validate the numerical analysis results, experimental analysis is been carried out. The experimental analysis is done by using infrared heating setup for various models by heating to specific temperatures for a certain period of time to find out the heat flow rate for the known thermal conductivity of the material. The experiment is concluded by finding out the material‟s thermal and physical properties along with variations in temperature profiles that are used inside the heater for insulation by the obtained results of numerical and experimental analysis.
