| Abstract | ||
| During this research, simulation of the candidate materials done as insulted brick for the furnace wall. Results were obtained through the use of simulation by COMSOL multiphysics program. Showed results obtained from this program, Al2O3 brick has high deformation value 2.34 *10-4 m and the maximum vonmises stress value 267 Mpa focused at the edges of the fifth slice. Vonmises stresses various along the slices of bricks of Al2O3-MgO, Al2O3-ZrO2 and MgO-ZrO2. Zirconia brick has 486 Mpa the maximum value of the vonmises stress. ZrO2 brick has low value 1.486 * 104 w/m2 of the total heat flux, while maximum value of the total heat flux occur in the Magnesia brick which has 2.267 * 105 w/m2. Structural brick of Al2O3-MgO has low total deformation value 7.987 * 10-5 m and low value of the maximum vonmises stress 133 Mpa. These data supporting use this brick of Al2O3-MgO as best candidate for the furnace wall without failure during the service. | ||
