Application of Back Propagation Neural Network to Drum Level …

The boiler drum process is a nonlinear, complex and multivariable process which includes significant time delay. Therefore, the control on the water level in the drum is not easy and ideal. The first objective of this paper is to model the drum water level referring to 210 MW power unit for Nassiriyah thermal power plant. The second objective is to study the water level controller operation

Low Drum Level in Boiler Operation - How to Handle - Bright Hub …

2009/9/30 · The boiler availability loss due to a low drum level operation can be a major concern in power plants, hence it is always better to take preventives. The effect of very low drum level operation is very severe that it can cause the water wall tubes to get overheated; it can cause snaking of water wall tubes leading to lot of projection in and out of furnace.
