Cfd Analysis of Circulating Fluidized Bed Combustion
In this paper computational analysis of circulating fluidized bed combustion using the fluent software is analysed. This work is concerned about gas–solid two-phase mixtures flowing upwards through the fast beds. The procedures studied are applicable to all types of fluidized-bed boilers. The type of information resulting from various ways of analyzing the pressure and temperature in fluidized ...
متن کاملBased 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 ...
متن کاملOlive Cake Combustion in a Circulating Fluidized Bed
In this study, a circulating fluidized bed of 125 mm diameter and 1800 mm height was used to find the combustion characteristics of olive cake (OC) produced in Turkey. Olive cake alone and olive cake+lignite coal mixtures were burned separately. Various olive cake/lignite coal ratios were tried. A suitable feeding mechanism of olive cake to the bed was developed. On-line concentrations of O2, S...
متن کاملTwo Phase Modeling of Char Combustion in a Circulating Fluidized Bed Reactor Using ASPEN PLUS
In this paper, combustion of char in the riser of circulating fluidized bed was modeled using ASPEN PLUS. Since physical and chemical phenomena are involved in the process, the model integrates the two-phase hydrodynamic sub-model with the reaction sub-model derived from the literature. In the proposed model, the fluidized bed is divided into several sections and the behavior of each section wa...
متن کاملReuse the Bed Ash from Circulating Fluidized Bed Combustion on Mortar Mixture
This paper investigates mortars consisting of various circulating fluidized bed combustion (CFBC) bed ash contents. The CFBC bed ash used in this study was obtained from Taiwan’s petroleum industry. This study presents experimental results on the flowability, compressive strength, drying shrinkage, scanning electronic microscopy (SEM) and mercury intrusion porosimetry (MIP) of mortar samples co...
