  2. 1. Steam Turbine Optimisation for Solar Thermal Power Plant Operation

    Author : James Spelling; Andrew Martin; Magnus Genrup; KTH; []
    Keywords : solar thermal power; steam-turbine; start-up; cool-down; dispatchability increase; koncentrerad solenergi; ångturbin; uppstart; nedkylning; ökad flexibilitet;

    Abstract : The provision of a sustainable energy supply is one of the most important issues facing humanity at the current time, given the strong dependence of social and economic prosperity on the availability of affordable energy and the growing environmental concerns about its production. Solar thermal power has established itself as a viable source of renewable power, capable of generating electricity at some of the most economically attractive rates. READ MORE

  4. 2. High temperature corrosion in a biomass-fired power boiler : Reducing furnace wall corrosion in a waste wood-fired power plant with advanced steam data

    Author : Yousef Alipour; Pamela Henderson; Peter Szalalos; Christofer Leygraf; Jan Froitzheim; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High temperature corrosion; Waterwalls; Power plant corrosion; NOx reducing enviroments; Biomass; Waste wood; Thermodynamic calculation modelling; corrosion-resistance alloy; Furnace wall corrosion; Högtemperaturekorrosion; Eldstadsväggar; kraftverks korrosion; låg Nox mijöer; biomassa; returträ; Termodynamisk modellering; korrosionsbeständighet legering; eldstadskorrosion;

    Abstract : The use of waste (or recycled) wood as a fuel in heat and power stations is becoming more widespread in Sweden (and Europe), because it is CO2 neutral with a lower cost than forest fuel. However, it is a heterogeneous fuel with a high amount of chlorine, alkali and heavy metals which causes more corrosion than fossil fuels or forest fuel. READ MORE

  5. 3. Fluidized bed plants for heat and power production in future energy systems

    Author : Guillermo Martinez Castilla; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass combustion; combined heat and power; thermal power plant; process control; operational flexibility;

    Abstract : Fluidized bed (FB) plants are used for heat and power production in several energy systems around the world, with particular importance in systems using large shares of renewable solid fuel, e.g., biomass. READ MORE

  6. 4. Developing Humidified Gas Turbine Cycles

    Author : Michael Bartlett; KTH; []
    Keywords : advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Abstract : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. READ MORE

  7. 5. Techno-economic analysis of combined cycle power plants integrated with chemical looping reforming and CO2 capture
