  1. 1. Reduction of Set-recovery of Surface densified Scots Pine by Furfuryl Alcohol

    University essay from Luleå tekniska universitet/Träteknik

    Author : Lei Han; [2019]
    Keywords : surface densification; set-recovery; hardness; furfuryl alcohol;

    Abstract :  For wood products such as flooring and worktop, only one surface is normally exposed in their use, and the mechanical properties like hardness and wearing resistance of that surface is then important. Since mechanical properties are strongly related to the density, surface densification, i.e. READ MORE

  2. 2. Production optimization for district heating : Short-term planning of district heating grid in Gävle, Sweden

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Nicolas Lindgren; Karl Brogren; [2019]
    Keywords : Short-term planning; Optimization; District heating; Linear programming; Mixed integer non-linear programming; Branch and bound; Heat storage; MATLAB; TOMLAB;

    Abstract : Energy systems with a high portion of renewable energy from wind and solar power can suffer from fluctuations in production due to weak winds or cloudy weather, which may affect the electricity price. When producing heat and power in a combined heat and power plant, an additional heat storage tank can be used to store the heat surplus which is obtained when the power production is high, and the heat demand is low.

  4. 4. Development and validation of a combined heat and power plant model for integration in DYESOPT

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : José Angel García; [2019]
    Keywords : ;

    Abstract : The liberalization of electricity markets and a growing penetration of renewables has led many countries to feel changes in the operation of their grids. The boundary conditions for the operation of conventional power plants are changing and, as such, an improved understanding of the varying loads and prices on the electricity grid is required to assess the performance of emerging combined cycle gas turbine (CCGT) concepts and to further optimize their design for these new markets in the pursuit of increasing their profitability, especially when considering co-generation of heat and power.

  5. 5. Potential measures and improvements in energy consumptions regarding ventilations systems with heat recovery

    University essay from KTH/Byggteknik och design; KTH/Byggteknik och design

    Author : Suat Uludag; Helmut Diliwi; [2019]
    Keywords : Ventilation System; System upgrade; Heat recovery; Energy consumption; Ventilationssystem; Systemuppgradering; Värmeåtervinning; Energianvändning; Energiförbrukning;

    Abstract : The ventilation system is in itself a huge necessity in our everyday life as it provides sufficient amount of fresh air to our indoor climate, while it simultaneously circulates the residing air pollutants out of the building. Although, for this to be made possible, large amounts of energy is required to be consumed, which in turn leads to an increased energy cost. READ MORE
