Research on Optimization of Coal Slime Fluidized Bed Boiler Desulfurization Cooperative Operation

Based on Multi-Sensor Information Fusion Circulating Fluidized Bed Boiler Combustion Process Clustering Control Research

Abstract Over the decade, due to the fact that the global energy resources are in deadly shortage, much emphasis is put on the energy consumption in thermal power throughout the world. Following developed is Circulating Fluidized Bed Boiler (CFBB) in recent years, a kind of combustion boiler that can clean and desulfurize the coal efficiently in the combustion process.Circulating Fluidized Bed ...

Study on PIDNN control of circulating fluidized bed boiler based on T-S model

Temperature and pressure are two main parameters of CFBB in the control system. Because of the CFBB possess the characteristics of time-varying, large lag and strong coupling, it is difficult to set up the arithmetical model and achieve better control effects. According to above difficulties, this paper adopts T-S fuzzy modeling method to description the input-output relationship for the contro...

Desulfurization of Coal

Fluidized Bed Desulfurization using Lime Obtained after Slow Calcination of Limestone Particles

In this work we have tested the fluidized bed desulfurization performance of lime particles obtained by means of a proprietary limestone slow calcination pre-treatment technique. This performance was compared to that of the parent untreated limestone particles. The occurrence of particle fragmentation and attrition during the fluidized bed operation was also investigated with a specific test pr...

Identification and MPC Control of a Circulation Fluidized Bed Boiler Using an LPV Model

This work studies the identification and control of circulation fluidized bed (CFB) boilers. The CFB boiler under investigation shows strong nonlinearity due to big changes of steam load. A linear parameter varying (LPV) model is used to represent the process dynamics and used in control. The steam flow is used as the working-point variable (scheduling variable) of LPV model. Multivariable plan...
