This paper presents a novel application of neural network modeling in the optimization of sensor locations for the measurement of flue gas flow in industrial ducts and stacks. The proposed neural network model has been validated with an experiment based upon a case-study power plant. The results have shown that the optimized sensor location can be easily determined with this model. The industry...

Since oxy-combustion is a relatively new technology, many problems associated with the behavior of coal in this novel combustion process still need to be solved. In particular, there is a lack of knowledge regarding the behavior of toxic trace elements, and there is a need to determine whether trace element distribution among the by-products and emissions to the environment, is comparable with ...

This paper discusses the modeling of the flue gas flow in industrial ducts and stacks using artificial neural networks (ANN’s). Based upon the individual velocity and other operating conditions, an ANN model has been developed for the measurement of the volume flow rate. The model has been validated by the experiment using a case-study power plant. The results have shown that the model can larg...

NOx removal from a smoke tube boiler flue gas was investigated using a commercial ozonizer for indirect NO oxidation and a Na2SO3 chemical scrubber. The flue gas flow rate was in the range of 410 Nm/h-1480 Nm/h, the gas temperature of 185 °C-325 °C, and NOx concentration of around 40 ppm in city gas firing. Operational and performance data were obtained. The NOx removal efficiency was clearly d...

This report is in two sections: the first describes the flue gas and its treatment in post-combustion capture and the second covers the flue gas in oxyfuel combustion capture. The main components of the flue gas in pulverised coal combustion for postcombustion capture are CO2, N2, O2 and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The ...

in this work, the adsorption of carbon dioxide from model flue gas on different adsorbents has been investigated. using simplified modeling, parameters such as the total mass transfer coefficient and the effective diffusivity have been determined. experiments were carried out in two sections: firstly, adsorption of pure carbon dioxide on different adsorbents was measured at pressures ranging fr...

A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical system was calibrated with liquid and/or gaseous standards. It was shown that identical mass flows of either gaseous or liquid standards resulted ...

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can
