Boiler Water-Steam System Modeling and Calibration Based on Modelica

Efficient model-based leak detection in boiler steam-water systems

A model-based least-squares algorithm with a time-varying forgetting factor is developed for leak detection in boiler steam-water systems. The algorithm has been tested using real industrial data from Syncrude Canada, and has proven to be effective in detection of boiler tube or steam leaks; proper implementation of the algorithm would lead to early leak warning, which is important in maintaini...

Control System Simulator for Steam Boiler Parameters

Abstract: The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water-steam system and furnace part of the boiler. Also, the paper presents the algorithm for real time detection of model parameter variations. In this context a correction method, validate through s...

A Steam - Boiler Control

Structural and Behavioral Models of the Steam-Boiler Control System

This paper presents a system specification of the steam boiler control system described in [?]: To manage complexity and to foster separation of concerns the design model is divided into three views: The architectural view specified with object and class diagrams, the reactive view specified with statecharts, and the functional view specified with Z. A systematic relationship between the reacti...

Modelica Based Dynamic Modeling of Water-Cooled Centrifugal Chillers

In this paper, the transient model of a water-cooled centrifugal chiller is developed in Modelica with Dymola and the TLK/IfT Library (TIL). The centrifugal compressor is modeled in detail based on the turbomachinery theory. The chiller capacity control is achieved by the combination of variable inlet guide vane (VIGV) and variable speed drive (VSD). The shell-and-tube heat exchangers are discr...
