Boiler Drum-level Modeling
In this paper, a mathematical model is developed to describe the dynamics of the drum-level of a natural circulation boiler. A boiler-drum is divided into two parts; the upper part contains saturated steam while the lower part contains a steam/water mixture. The ratio of the steam in that mixture is defined in this work as the steam volumetric ratio. On the other hand, balance equations are app...
متن کاملDrum-boiler dynamics
A nonlinear dynamic model for natural circulation drum-boilers is presented. The model describes the complicated dynamics of the drum, downcomer, and riser components. It is derived from "rst principles, and is characterized by a few physical parameters. A strong e!ort has been made to strike a balance between "delity and simplicity. Results from validation of the model against unique plant dat...
متن کاملModel Based Predictive Control of a Drum-type Boiler
High fuel costs, stringent safety and pollution standards and the need to increase plant life-time have all driven the search for better boiler control. Traditional PID control cannot achieve the best possible results as it does not account for the strong interactions between the controlled variables. Much work has been done in the area of optimal control, but the improvements gained in perform...
متن کاملBoiler Drum Level Control Using Internal Model Controller
The water level of boiler drum is one of the crucial control parameters for any process industry which reflects the control of mainly boiler load and feed water indirectly. If the level exceeds the limits, boiler water carryover into the superheater or the turbine may cause damage resulting in extensive maintenance costs. If the level is low, overheating of the water wall tubes may cause tube r...
متن کاملANFIS Controller for Water Level Control of a Boiler Drum
The water level in boiler drum is the critical control parameter to be addressed for providing the efficient and safe operation of steam generators in power plants. The regulation is achieved by using the Artificial Intelligence (AI) technique, namely, Adaptive Neuro-Fuzzy Inference System (ANFIS). It has the capability of self-learning as ANN with the linguistic expression function of fuzzy in...
