    University essay from Högskolan i Gävle/Elektronik

    Author : Sedat Polat; [2020]
    Keywords : ;

    Abstract : The aim of this thesis is to develop a Selective Non-Catalytic Reduction (SNCR) system which is based on a control system to keep NOx emissions from combustion by maximum 27 kg/h urea consumption and then perform commissioning on the site. The NOx value in the combustion is around 220 mg/Nm3 under 100% laud. READ MORE

  2. 2. Rock cavern as thermal energy storage

    University essay from Luleå tekniska universitet/Energivetenskap

    Author : Simon Berglund; [2020]
    Keywords : Rock cavern; Waste heat; District heating; Intermittent operation; Sustainability; Heat storage; Carbon dioxide reduction; Bergrum; Spillvärme; Fjärrvärme; Intermittent drift; Hållbarhet; Värmelagring; Koldioxid reducering;

    Abstract : In the fall of 2019, a comprehensive idea study was conducted on heat storage in two rock caverns located at Näsudden in Skelleftehamn and was part of the project course "Energiteknik, huvudkurs" at Luleå University of Technology. This idea study investigated the conditions of using waste heat from Boliden AB:s copper smeltery (Rönnskär) and storing this waste heat in two rock caverns and use them as seasonal thermal storage tanks, with the purpose of using the heat in the nearby district heating network, thus replacing some of the oil burned at Rönnskär.

  3. 3. Behaviour of NOx sensors at their end of life

    University essay from KTH/Förbränningsmotorteknik

    Author : Jose Mathew; [2020]
    Keywords : NOx sensor; failure modes; oscillatory fault monitor; diagnosis of sensors; NOx sensor; felfunktioner; oscillerande felmätare; diagnos av sensorer;

    Abstract : NOx-sensorn är grundläggande i det moderna efterbehandlingssystemet och dess pålitlighet är avgörande för att kunna leva upp till rådande emissionslagkrav. Livslängden samt sensorns beteende i slutet av denna varierar betydligt. READ MORE

  4. 4. Green Fuel Simulations

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Daniel Gutiérrez; [2020]
    Keywords : Industrial gas turbines; Combustion instabilities; Computational fluid dynamics; Acoustics; COMSOL Multiphysics; Flame transfer function;

    Abstract : Many industries have entered a new global phase which takes the environment in mind. The gas turbine industry is no exception, where the utilization of green fuels is the future to spare the environment from carbon dioxide and NOx emissions. READ MORE

  5. 5. Highway to Hell? : Evaluating the effect of environmental policy on emissions from the Swedish truck fleet

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

    Author : Eleanor Johansson; [2019]
    Keywords : Transportation; Low emissions zones; Environmental policy; Trucks; Clean technology; Command and control policy; Euro classification; Transport; Miljözon; Miljöpolitik; Lastbilar; Ren teknologi; Euro klassifikation;

    Abstract : The aim of this thesis is to examine the emissions from the Swedish truck fleet between 2007- 2014. By descriptive analysis the emissions of NOx, PM, HC and CO are found to decrease at the truck level, the firm level and municipal level. READ MORE
