Application of fuzzy model predictive control to a drum …

1/1/2006 · Economic feasibility of a power plant requires smooth and uninterrupted plant operation in the face of varying electrical power demand. The feed-water system in a power plant is a major contributor to plant unavailability. In this paper, a fuzzy model predictive control (FMPC) approach is introduced to design a level control system in a drum boiler. In this approach, the process is described

Drum-boiler dynamics - ScienceDirect

The boiler of coal-fired thermal power plant consists of integrating process units such as the furnace, economizer, drum, and superheater. There is a lack of proper dynamic model derived from mass and energy balances of individual units integrated together where dynamics of material and energy flow are not understood properly supporting the larger footprints and environmental impact of the

Drum-boiler dynamics - ScienceDirect

1/3/2000 · A schematic picture of a boiler system is shown in Fig. 1. The heat, Q, supplied to the risers causes boiling.Gravity forces the saturated steam to rise causing a circulation in the riser-drum-downcomer loop. Feedwater, q f, is supplied to the drum and saturated steam, q s, is taken from the drum to the superheaters and the turbine.

This paper describes a nonlinear dynamic model for natural circulation drum-boilers. The nonlinear model which is intended for model based control focuses on the complicated dynamics ofthe drum, downcomer, and riser components. A strong effort has been made to strike a balance between fidelity and simplicity. The model is derived from first principles, and is characterized by a few physical
