  2. 1. Impacts of alternative combustion diluents and hydrogen addition on a swirl-stabilized flame related to gas turbine application

    Author : Mao Li; Kraftverksteknik; []
    Keywords : lean premixed combustion; Swirl-stabilized flame; Gas turbine combustion; Flame dilution; H2 addition; Lean blowout; CO emission; PVC; CH chemiluminescence; Inverse Abel transform; PIV; POD;

    Abstract : The global energy tendency leads to increasing attention on clean combustion technologies in order to eliminate adverse impacts on the environment. The utilization of oxyfuel combustion (CO2 acts as the only combustion dilution), flame diluents, and hydrogen fuel in gas turbine combustion provides a promising solution to reduce combustion pollutant emissions.

  4. 2. Mechanism of a polyolefin based effervescent flame retardant material

    Author : Anna Lundgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intumescent structure; flame retardant; Casico; silicone elastomer; polyolefin; effervescence; calcium carbonate;

    Abstract : ABSTRACTFire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start and/or spread a fire. As a result of environmental and safety issues having to do with flame retardants based on halogens, much attention has lately been given to finding halogen free alternatives. READ MORE

  5. 3. Polyolefin Flame Retardant Cable Materials - Effect of Additives and Copolymer Structure

    Author : Linus Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Carbonate; Flame Retardant; Silicone Elastomer; Melt Viscosity; Ethylene-Acrylate Copolymer;

    Abstract : Fire safety of cables is becoming increasingly important as the use of electrical equipment steadily increases. Due to their excellent dielectric properties, polyolefin materials are widely used as insulating materials for cables. However, polyolefins are inherently flammable and need to be protected to meet the requirements on flame retardancy. READ MORE

  6. 4. Low smoke halogen-free materials for wire and cable applications

    Author : Anna Lundgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame retardant; calcium carbonate; calcium silicate; Casico; polyolefin; effervescence; intumescent structure; thermal degradation; silicone elastomer;

    Abstract : Fire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start a fire and/or spread one. Traditionally, materials containing halogen have been used as primary insulation in low voltage power and telecommunication cables and most cables used today therefore contain halogen. READ MORE

  7. 5. Spark Assisted Compression Ignition, SACI

    Author : Håkan Persson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame propagation; PLIF; LDV; chemiluminescence imaging; residuals; negative valve overlap; low temperature combustion; SACI; spark assistance; HCCI; turbulence; charge stratification; cycle to cycle;

    Abstract : The strong focus on decreasing carbon dioxide emissions due to limited natural resources of fossil fuel as well as alarming climate changes drives the research and development of our prime mover, the combustion engine, faster then ever. The minimum requirement is a power source with increased efficiency while emitting ultra low levels of hazardous local and regional emissions. READ MORE
