   Sammanfattning : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. LÄS MER

3. 2. A steady flameless light : the phenomenology of realness in Dorothy Canfield Fisher's The brimming cup, Her son's wife and Rough-hewn

   Författare :Annika Ljung-Baruth; Hans Löfgren; Stockholms universitet; []
   Nyckelord :Dorothy Canfield Fisher; Literature; Litteraturvetenskap;

   Sammanfattning : This study investigates the way in which experience comes to givenness in three novels by the early twentieth century American writer Dorothy Canfield Fisher (1879-1958). By utilizing a model of affectivity set up by the French phenomenologist Michel Henry, the investigation uncovers unthematized strata in The Brimming Cup (1921), Rough-Hewn (1922), and Her Son’s Wife (1926) in which subjectivity is phenomenalized as auto-affective and immanent.

4. 3. Experimental investigation of flows related to gas turbine combustion

   Författare :Dragan Stankovic; Strömningsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; combusiton; flameless; jets in cross flow; chemiluminescence; POD; LIF; PIV; Spray; Gas Turbine; single digit NOx; Premixed Combustion; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Sammanfattning : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.

5. 4. Thermodynamic aspects and heat transfer characteristics of HiTAC furnaces with regenerators

   Författare :Nabil Rafidi; Wlodzimierz Blasiak; John Witton; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; flameless; oxy-fuel; heat-recirculation; gas-recirculation; heat transfer; furnace; radiant-tube; regenerative burner; honeycomb; fixed-bed; Thermal energy engineering; Termisk energiteknik;

   Sammanfattning : Oxygen-diluted Combustion (OdC) technology has evolved from the concept of Excess Enthalpy Combustion and is characterized by reactants of low oxygen concentration and high temperature. Recent advances in this technology have demonstrated significant energy savings, high and uniform thermal field, low pollution, and the possibility for downsizing the equipment for a range of furnace applications.
