Significant progress has been made in both experimental investigations and numerical modelling of oxy-fuel combustion for CO2 capture purposes at the CANMET Vertical Combustor Research Facility. Detailed in-flame measurements have revealed insights into flow field development and pollutant...

Oxy-fuel circulating fluidized bed combustion (CFBC) is an alternate technology to oxy-fuel pulverized combustion (PC), which has a number of advantages that can often make it a better choice for CO2 capture. This paper presents experimental results and operating experiences from a 0.8MWth...

We examine shareholders' wealth effects (both in the short- and the long-run) of UK frequent bidders acquiring public, private, and/or subsidiary targets with alternative methods of payment between 1987 and 2004. We find that, in the short-run, bidders break even when acquiring public targets...

We discuss the optimal operation of a combined heat and power (CHP) plant with heat storage. The dynamics of the district heating (DH) network are also considered. The decision variables include production of heat and power, supply temperature and operation of heat storage. Heat demand for the...

In order to develop more efficient and cleaner gasoline engines, a number of new engine operating strategies have been proposed and researched on different engines, including the spark ignition (SI) and controlled autoignition (CAI) or HCCI in both 2-stroke and 4-stroke cycles in a poppet valve...

The paper presents a relatively simple model describing the nitrogen dynamics in an alternating waste water treatment process. Only two components, ammonia and nitrate plus nitrite, are considered, and reaction rates are described using empirical expressions. Despite its simplicity, the model...

Hidden regularities of complex networks may be different from the properties they show to us externally. In this paper, organization of rich nodes in real world and model networks are investigated. It is found that in scale-free networks, when the rich level is relatively low, the degree...
