Prediction of risers' tubes temperature in water tube

The boiler under consideration here is of the water-tube natural circulation type. The main components of such a boiler are the steam drum, the downcomer tubes and the riser tubes which represent the complete fluid flow loop. Feedwater enters the boiler steam drum from the economizer or from the feedwater heater if there is no economizer.
