Question: 15 points furnaces are used to heat process streams to...

Question details

(15 points) Furnaces are used to heat process streams to high temperatures before further processing. Consider the temperature control loop for a furnace shown in Figure 1. Draw a logic flow diagram similar to shown in class, i.e. assemble each element of the temperature loop for the furnace to form a feedback block diagram. Also, identify the control variables (CVs), manipulated variables (MVs), dependent variables (DVs), independent variable (IVs), processes, sensors and actuator for this process and indicate what are the specific disturbances for this control loop.
