4. Results of tested fluidized bed combustor system

We will see the test combination of developed fluidized bed combustor system by using Taguchi method is as follow

By using Taguchi method we get optimum result. Result obtain from Mini-tab software are as follows

Chart -1: S N ratio graph for parameters According to above test sand reclaimed quantity and cycle time are as follows

The factor levels corresponding to the highest S/N ratio were chosen to optimize the condition. From these
