Input variable, % open 6.1. An experiment has been performed on a fired heater (furnace). The fuel valve was opened an additional increment of 2 percent in a step, giving the resulting temperature response in Figure Q6.1. Determine the model parameters using both process reaction curve methods and estimate the in- accuracies in the parameter values due to the data and calculation methods. 505 10 15 20 25 30 Time 15 10 0 Output variable, C FIGURE Q6.1 Input variable, % open 6.1.
