The mechanical effects in the boiler of steam power plants are a very complex problem and dangerous because of unstable pressure in the upper drum boiler. This work deals with an experimental investigation of the drum water level system in (Al-Quds power plant) in Baghdad / Iraq to explain the dynamic behavior of the system under a given operating condition. Mathematical equations of the boiler model are solved. The rapid elevation in the heat input (mass flow rate of fuel) has a dynamic effect on the riser tubes properties in the natural water circulation tube in a steam power plant's boiler. These are typically calculated under increasing heat input by ratio 10% and 20% for upper drum parameters. The outcomes represented that the rapid rise in the fuel flow rate leads to increase rates of evaporation and consequently caused a high elevation in the quality and this causes tube overheating. The temperature of the riser rising above the saturation temperatures slightly because of the steam temperature altitude and the dynamic influence resulting from a sharp rise in the thermal flux.
