1. 16. Ångdrift av värmepumpar i Solnaverket : En teknisk och ekonomisk studie över konvertering från eldrift till mekanisk ångdrift

   Uppsats för yrkesexamina på avancerad nivå,

   Författare :Josephine Lindén Magnusson; [2020]
   Nyckelord :heat pump; steam turbine; capacity shortage; district heating; energy engineering; värmepump; ångturbin; kapacitetsbrist; fjärrvärme; energiteknik;

   Sammanfattning : This master thesis has examined how two of the heat pumps at Norrenergi, Solnaverket, can be converted to steam driven heat pumps. The heat pumps are driven by electrical motors today and this thesis has investigated the technical and economical aspects of replacing them with steam turbines and also installing a pellet boiler.

   Nyckelord :Recovery boiler; pulp production; steam production; heat transfer; super heater; boiler efficiency; steam production; Sodapanna; pappersmassatillverkning; ångproduktion; värmeöverföring; överhettare; panneffektivitet; elproduktion;

   Sammanfattning : The industrial sector in Sweden stands for 38 percent of the total energy use. Within these 38 percent the pulp and paper industry stand for about half of the energy use. Due to the extent of the energy use it is important that we do what we can to keep the energy usage as low as possible within our industries. LÄS MER

5. 19. Distribution of bed material in a Horizontal Circulating Fluidised Bed boiler

   H-uppsats,

   Författare :Thomas Ekvall; Robin Magnusson; [2019-07-03]
   Nyckelord :Energi; Hållbar utveckling; Energiteknik; Miljöteknik; Energy; Sustainable Development; Energy Engineering; Environmental engineering;

   Sammanfattning : A conventional circulating fluidised bed (CFB) boiler has a limitation due to the height of the furnace, when implemented in smaller industrial facilities. The design of a horizontal circulating fluidised bed (HCFB) boiler is an interesting approach to resolve this problem. LÄS MER

7. 20. Thermodynamic and Economic Evaluation of Hybridization Biomass-solar for a Cogeneration Power Plant in a Cuban Sugar Mill, George Washington

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Silja Lehtinen; [2019]
   Nyckelord :;

   Sammanfattning : This study evaluates the thermodynamic and economic performance of hybridization of biomass-solar for a cogeneration power plant in a Cuban sugar mill, George Washington. The evaluation is performed by varying the parameters of the thermal power block and considering scenarios with 1) bagasse and marabú, 2) bagasse and solar field, and 3) bagasse, marabú and solar field as heat sources for the cogeneration cycle.
