Merging of energy and environmental analyses for district heating systems
Torchio, Marco F.; Genon, Giuseppe; Poggio, Alberto; … - In: Energy 34 (2009) 3, pp. 220-227
District heating (DH) systems, together with combined heat and power (CHP) plants, have been increasing both in number and interest over the last decade, but the environmental improvements are still controversial, because although there is usually a reduction in CO2 emissions, a positive effect...

Review of gas/particle flow, coal combustion, and NOx emission characteristics within down-fired boilers
Kuang, Min; Li, Zhengqi - In: Energy 69 (2014) C, pp. 144-178
Low-volatile fuels such as anthracite and lean coal are widely used in power generators throughout the world. In comparison with tangential-fired and wall-arranged furnaces, down-fired boilers are thought to be more suitable for firing anthracite and lean coal. Currently, down-fired boilers are...

The effects of steam injection on the performance and emission parameters of a Miller cycle diesel engine
Gonca, Guven; Sahin, Bahri; Parlak, Adnan; Ust, Yasin; … - In: Energy 78 (2014) C, pp. 266-275
The application of the Miller cycle into the internal combustion engines is proposed to decrease NOx emissions, in the recent years. Another NOx control technique is the steam injection method (SIM). In this study, the application of these methods together into a single cylinder, direct...

Development of a model for the prediction of the fuel consumption and nitrogen oxides emission trade-off for large ships
Larsen, Ulrik; Pierobon, Leonardo; Baldi, Francesco; … - In: Energy 80 (2015) C, pp. 545-555
The international regulations on fuel efficiency and NOx emissions of commercial ships motivate the investigation of new system layouts, which can comply with the regulations. In combustion engines, measures to reduce the fuel consumption often lead to increased NOx emissions and careful...
