The photooxidation of diethyl ether (C2H5OC2H5) and diisopropyl ether, (CH3)2CHOCH(CH3)2, in the presence of NOx was studied at the European Photoreactor (EUPHORE) in May 1998. The main objective of the experiments was to validate the degradation mechanisms that are based on data obtained from laboratory photoreactor studies. For diisopropyl ether, the experiments provided product yield data th...

Fly ash generated from low NOx burners at American Electric Power's Glen Lyn facility was beneficiated to remove residual carbon, magnetic particles, and cenospheres. The clean fly ash had a mean particle size of about 30 microns, which is coarser than typical commercial fillers used in plastics. To obtain a finer sized fly ash, air classification was used to separate the clean fly ash into its...

The process of making cement clinker uses a lot energy and produces pollution. Currently, companies use combination traditional fossil fuels alternative (AF-Fuels) to lower their consumption environmental footprint by improving the pyro-system. In calciner, AF-Fuels can reach thermal substitution rate (TSR) up 80–100%. However, kiln burner only achieve TSR 50–60%. High values have been provided...

Modeling NOx emissions from coal fired utility boiler is critical to develop a predictive emissions monitoring system (PEMS) and to implement combustion optimization software package for low NOx combustion. This paper presents an efficient NOx emissions model based on support vector regression (SVR), and compares its performance with traditional modeling techniques, i.e., back propagation (BPNN...

Since the Euro-III standard was adopted, the main methods to inhibit NOx production in diesel engines are exhaust gas recirculation (EGR) and select catalyst reduction (SCR). On these methods SCR offers great fuel economy, so it has received wide attention. However, there also exists a trade-off law between NOx conversion efficiency and NH3 slip under dynamic conditions. To inhibit NH3 slip wit...
