1. 16. Heat Transfer in Circulating Fluidized Bed Boilers

   Författare :Claes Breitholtz; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; similarity; char; heat transfer; tube wall; circulating fluidized bed; particle; radiation; scaling; particle convection; gas convection;

   Sammanfattning : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. LÄS MER

3. 17. A Silent Revolution : The Swedish Transition towards Heat Pumps, 1970-2015

   Författare :Petter Johansson; Pär Blomkvist; Martin Vendel; Eric Giertz; Mats Fridlund; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; heat pumps; socio-technical transition; sustainability transition; industrial dynamics; value networks; coopetition; complementarities; strategic management; värmepumpar; socio-tekniska övergångar; hållbarhet; industriell dynamik; värdenätverk; coopetition; komplementariteter; företagsstrategi; Industriell ekonomi och organisation; Industrial Economics and Management;

   Sammanfattning : Currently, more than half of all Swedish single-family houses have an installed heat pump and more heat is supplied by heat pumps in Sweden than in any other nation. Despite the enormous impact of heat pumps on the Swedish energy system, the transition towards their use has gone relatively unnoticed. LÄS MER

4. 18. Integrating Latent Heat Storage into Residential Heating Systems : A study from material and component characterization to system analysis

   Författare :Tianhao Xu; Samer Sawalha; Björn Palm; Justin NingWei Chiu; Tianshu GE; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase change material; thermal energy storage; heat pump; load shifting; space heating; Energy Technology; Energiteknik;

   Sammanfattning : Latent heat thermal energy storage (LHTES) systems can be coupled with heat pump (HP) systems to realize heat load shifting on demand side. With phase change material (PCM), well designed LHTES components exhibit high storage energy density and thus have large potentials to be integrated in residence where a compact energy storage solution is needed.

7. 20. Radiative Heat Transfer in Suspension-Fired Systems

   Författare :Adrian Gunnarsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-firing; rotary kiln; combustion; Radiative heat transfer; soot volume fraction;

   Sammanfattning : Radiation is the dominating heat transfer mechanism in most furnaces, and the radiative properties of combustion products represent important aspects regarding its suitability as a heat source. However, fuel and energy markets are undergoing rapid changes due to increasing concerns related to the security of supply and increased global warming. LÄS MER
