Effects of common fuel and heating system options on the energy usage, pollutant emissions and economy

Annual fuel and energy consumptions and CO2 and SO2 emissions of various fuel (natural gas, fuel oil, coal, lignite, electricity) and system alternatives (individual, central, district) for hot water and space heating are compared. Further, detailed economical analyses illustrate the dependency of the life cycle costs on fuel and system types, building size and location, inflation and interest rates. It is found that natural gas systems lead in all respects, but fuel oil systems follow closely in many cases. Coal and lignite cannot compete at all, except possibly lower SO2 emissions of imported low-S coal in comparison to typical fuel oils. Direct electrical heating and even electrical heat pumps should be discouraged because of their markedly inferior performance. Also, district and central systems could provide savings (about 20% and 5%, respectively) in comparison to individual systems using identical energy resources.


Effects of heat input on metallurgical behavior in HAZ of multi-pass and multi-layer welded IN-939 superalloy
Mashhuriazar, Amirhossein; Gür, Cemil Hakan; Sajuri, Zainuddin; Omidvar, Hamid (2021-11-01)
The hot components of a gas turbine are susceptible to damage in the high-temperature environment of turbine engine operation. Given that these components are relatively costly to manufacture, they are often repaired than replaced when damaged. Fusion welding is an economical method for repairing the damaged components of a gas turbine. This research examines the roles of heat input, pass number and layer number on the intergranular liquation cracking of the Inconel-939 (IN-939) precipitate nickel base supe...
The effects of promoters on the sulfur resistance of nox storage/reduction catalysts : a density functional theory investigation
Koşak, Rukan; Toffoli, Daniele; Toffoli, Hande; Department of Chemistry (2011)
High fossil fuel consumption in transportation and industry results in an increase of the emission of green-house gases. To preserve clean air, new strategies are required. The main intention is to decrease the amount of CO2 emission by using lean-burn engines while increasing the combustion efficiency and decreasing the fuel consumption. However, the lean-burn engines have high air-to-fuel ratio which complicates the reduction of the oxides of nitrogen, NOx . The emission of these highly noxious pollutants...
Study of water-oil emulsion combustion in large pilot power plants for fine particle matter emission reduction
Allouis, Christophe Gerard; L'Insalata, A.; Fortunato, L.; Saponaro, A.; Beretta, F. (2007-04-01)
The combustion of heavy fuel oil for power generation is a great source of carbonaceous and inorganic particle emissions, even though the combustion technologies and their efficiency are improving. The information about the size distribution function of the particles originated by trace metals present into the fuels is not adequate. In this paper, we focused our attention the influence of emulsion oil-water on the larger distribution mode of both the carbonaceous and metallic particles. Isokinetic sampling ...
Improved wind power forecasting using combination methods
Köksoy, Ceyda Er; Birtürk, Ayşe Nur; Karagöz, Pınar; Department of Computer Engineering (2015)
Wind is an important renewable energy source to produce electricity thanks to its reliable, omnipresent and economically feasible characteristics and it has a growing proportion in overall energy production worldwide. However, integration of the generated wind power into the existing transmission grid is an issue due to inherently volatile and intermittent behavior of wind. Moreover, the power plant owners need reliable information about day-ahead power production for market operations. Therefore, wind powe...
Effects of Wind Turbines on Voltage Profile
Abedinzadeh, Taher; Ehsan, Mehdi; Afsharirad, Hadi; Nazaraliloo, Mohammad (2011-09-10)
For distribution grids connected wind power generation, voltage quality is an important issue for the system planning purpose. The operation of wind turbines in the distribution networks may affect the voltage quality offered to the consumers. One of the most important considerations is the effect on the voltage profile, i.e. the induced slow voltage variations, which are the subject of this paper.
