1. 16. Automatic Control for a Gas System Using PIC Microcontroller

   Kandidat-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

   Författare :Ziyu Liu; [2014]
   Nyckelord :methane; PIC; automatic control;

   Sammanfattning : In many processes it is important to have automatic control in the modern life. For example, PLC systems are using for machine control, water pressure and flow are able to be controlled by DDC program, even a car can be driven by computer. In this article, author will turn our focus on the control system for fermentation tank. LÄS MER

3. 17. Flexible Ignition System for a Gas Turbine

   Master-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Anton Berg; [2012]
   Nyckelord :Gas turbine; ignition; methane; propane; CO2; N2; ignition energy; ignition delay time;

   Sammanfattning : Siemens Industrial Turbomachinery AB produce five gas turbines models. The SGT-700 can currently only start on gases which contain low amounts of inert gases. It is therefore of interest to widen the fuel range which the SGT-700, as well as other gas turbines, can start on. LÄS MER

4. 18. FEASIBILITY STUDY OFSTAND-ALONE SMALL-SCALE DIGESTION SYSTEMSTO PRODUCE BIOGAS FOR LOCAL USE

   Master-uppsats, KTH/Energiteknik

   Författare :Marie Janet Eustasie; [2012]
   Nyckelord :;

   Sammanfattning : The purpose of this project was to carry out a feasibility study of implementing a small-scale biogas plant on KTH campus using food wastes from the neighbouring restaurants and KTH kitchens as input substrate, where the biogas produced could be used in the Energy laboratory, to run the micro turbine, as an example. Considering that KTH has 10 departments and that each department has its own kitchen, the amount of food wastes that can be recuperated for input to the plant is around 225 kg per day for a normal working week, requiring a 10m3 biogas plant.

5. 19. Effect of Temperature on Biogas Production in Anaerobic Treatment of Domestic Wastewater UASB System in Hammarby Sjöstadsverk.

   Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

   Författare :Chengyuan Zhao; [2011]
   Nyckelord :Anaerobic wastewater treatment; UASB reactor; Domestic wastewater; Temperature; COD; Biogas production; OLR;

   Sammanfattning : The upflow anaerobic sludge blanket (UASB) reactor is widely used around the world to treat variety of domestic andindustrial wastewater with three main advantages: production of biogas as renewable energy, no need of support structure for development of microorganisms and high rate treatment efficiency with low rate of biomass production. This study evaluates the effect of temperature on biogas production and CODtotal removal in Line 4-UASB system treating domestic wastewater in Hammarby Sjöstadsverk. LÄS MER

7. 20. ASSESSMENT OF MACROALGAE HARVESTING FROM THE BALTIC SEA FROM AN ENERGY BALANCE PERSPECTIVE

   Master-uppsats, KTH/Industriell ekologi

   Författare :Olena Tatarchenko; [2011]
   Nyckelord :Baltic Sea; Macroalgae; Biogas; Energy balance; Life cycle assessment;

   Sammanfattning : Energy balance of large-scale and small-scale scenarios of macroalgae harvesting for biogas production was assessed from the energy balance perspective. Evaluation was based on primary energy Input Output (IO) ratio where all primary energy inputs into the stages of the process life-cycle were summarized and divided by the final energy output from the system.
