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. The Analysis of Thermal Power Stations and their Interaction with the Power System using Simulator Test Methods

   Author : Jan Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal power station; network simulator; frequency control; island operation; turbine model;

   Abstract : This thesis describes a new method of testing power stations with regard to their frequency control behaviour and analyses results obtained using this new method. The test concept is based on that the power station unit to be tested remains synchronized onto its normal strong network, whereas the frequency control behaviour is set up to be that of the conditions if the unit was working on a much smaller network, using a computer based simulator system and feeding simulated control signals to the input of the units frequency control system.

7. 5. Hybrid Solar Gas-Turbine Power Plants : A Thermoeconomic Analysis

   Author : James Spelling; Andrew Martin; Björn Laumert; David Tomas Sanchez Martinez; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar thermal power; hybrid gas-turbine; thermoeconomics; koncentrerad solenergi; gas-turbiner; ekonomisk analys;

   Abstract : The provision of a sustainable energy supply is one of the most importantissues facing humanity at the current time, and solar thermal power hasestablished itself as one of the more viable sources of renewable energy. Thedispatchable nature of this technology makes it ideally suited to forming thebackbone of a future low-carbon electricity system. READ MORE
