“…For example, compared to the use of motorcycles and personal cars, case studies indicate that public buses reduce both local and global greenhouse gas emissions and stimulate changes in policy, vehicle engine technology, and user behaviour (Dirgahayani, 2013). Even so, some conceptual examples also indicate both environmental and economic benefits from large integrated district heating systems compared with decentralised heating (Wang et al, 2010). Furthermore, if these large technical systems are designed and developed using extended insights from ecodesign and PSS design, potentially radical system-wide environmental improvements can be obtained acknowledging the decisive role the design dimension contributes to the environmental performance of environmental technologies (Carrillo-Hermosilla et al, 2010).…”

In iron ore pellet production, an increased green pellet temperature has a positive influence on the straight grate induration furnace. Previous studies show that this can lead to both higher production capacity of the induration furnace and also reduced specific oil consumption. The aim of this study is to apply the process integration concept to analyze how to maintain a high green pellet temperature by using the available heat more effectively. The heat is today used for the indoor climate and is delivered by electricity boilers and a waste heat recovery boiler that is installed next to the induration furnace, using hot gases from the furnace to heat water. This work will however assume that one can use the heat from the waste heat recovery boiler to preheat the material stream. By optimizing the cold section of the pelletizing plant, using process integration and the mathematical modeling approach in combination with the newly developed Optimal Solution Space Method, the results show that it is possible to increase the green pellet temperature and also reduce the energy cost by using the available energy in a more efficient way. It is also showing that by retrofitting the system so that the waste heat from the waste heat recovery boiler is used to preheat the material stream, this also leads to reduced energy cost and also increased production of iron ore pellet since the temperature of green pellet will be higher.

“…The work included studies of possible technologies, as well as technical and economical calculations and optimizations. The optimizations were based on process integration using the tool reMIND, which had been developed together with Linköping University [4] and is extensively used with Swedish steel and mining industry [5][6][7] as well as abroad [8,9]. It was also decided to base the study on production data from the year 2006.…”

The surplus energy in rest gases are an important by-product in the steel plant in Luleå. The surplus is used in a local heat and power plant. Studies have been and are being carried out to find alternative use for the high calorific ones, especially the coke oven gas. A limitation could be fluctuations in gas availability. The scope of this work has been to study these fluctuations and estimate possible effects on the use. Logged data from one year of the steel plant have been used. A large part of the signals have non-periodic contents and/or irregularly distributed transients. A specific technique, wavelet analysis, has been used to handle that. For this reason the signals were analysed using wavelet analysis.The study shows that there are important gas fluctuations that could influence external use, e.g., for fuel production and that the behavior was non periodic. In addition to variations in frequency and amplitudes, there are also different shapes of the fluctuations, e.g. a relatively high ratio of "spikes" that could be up-or downward to the final users. The fluctuations are of both short and long wavelength. Longer wavelengths could probably be parried by good production planning. For short wavelengths some kind of safety margin could be appropriate, perhaps in the range 0.75-1.5 kNm 3 /h. The existing buffer capacity in gasholders etc. is too small to cover the
