A weighted algorithm of fuzzy logic strategy on Water level control of steam generator
Proceedings of the 36th IEEE Conference on Decision and Control, 1997Co-Authors: Tianyou ChaiAbstract:This paper presents the newly developed Water level control system for drum Boiler using the fuzzy control strategy. The major dynamics of Boiler Water level include nonlinearities, nonminimum phase behavior, instabilities, time delays, and load disturbances. A weighted algorithm of fuzzy logic strategy is applied to control the steam Boiler using the GPE (Gaussian partition with evenly spaced midpoints) system. The fuzzy logic controller has been tested in a real plant and the results obtained are shown.

Studying the effect the initial thermal state of a heat-recovery Boiler’s evaporating system has on its performance characteristics during startup
Thermal Engineering, 2010Co-Authors: V. A. Dvoinishnikov, E. A. PopovAbstract:The influence of the initial temperature of Boiler Water on the indicators characterizing the performance of the circulation system of heat-recovery Boilers with natural and forced circulation during their startups from a cold state is investigated. Specific features pertinent to operation of a heat recovery Boiler’s circulation system in the Boiler starting mode are revealed.

Supercritical once-through Boiler Water-coal ratio modelling and character study
The 27th Chinese Control and Decision Conference (2015 CCDC), 2015Co-Authors: Heng Zhang, You LvAbstract:The supercritical once-through Boiler is a complex system with the characteristics of strong coupling, non-linearity and multiple parameters. Quick and accurate acquisition of its Water-coal ratio is the guarantee of the Boiler's safe, economic and stable operation. The turbine heat rate calculation method based on unit operation data was introduced in this paper. Then by the matter and energy conservation, the Water-coal ratio calculation model was derived from the relation between Water-coal ratio and heat rate. Finally, taking a certain 600MW coal-fired unit as example, the Water-coal ratio under rated conditions were calculated by the put forward model. The result is indicated that the model is efficiency and reasonable from theoretical analysis and practical application. The obtained Water-coal ratio character is of great significance for supercritical once-through Boiler control improvement.
