Major incentives on wind and solar power and decreasing consumption have nearly stalled thermal power investments in Europe. While fossil fuels are facing strong political pressures there seems to be a market for CO2 neutral thermal power and heat production. Today’s market situation calls for fuel flexible technologies, coordinated efforts in the integration of contractual and financial structures and several power generation technologies, while maximum efficiency and economics of scale drive towards utility size solutions. MGT Teesside Limited has selected Técnicas Reunidas (TR), in a consortium with Samsung C&T, for the execution of a contract to build a new 299-MWe combined heat and power (CHP) plant within the Teesport Estate near Middlesbrough, U.K.
Amec Foster Wheeler will design and supply the single circulating fluidized bed (CFB) boiler of the CHP plant, taking the CFB to the 299-MWe scale with 100% biomass fuels, i.e. wood pellets that will be sourced from sustainable forest by-products in North America and sustainable wood chips mainly from the United Kingdom. Besides providing nearly CO2 free energy by using renewable fuels, the plant will fulfil the most stringent emission limits set for traditional (SOx, NOx, dust) as well as previously unlimited pollutants, such as NH3, Hg, HCl and HF.
High-efficiency biomass power plants need to utilize advanced steam parameters and in Tees REP they are 176 / 43.8 bar(a), 568 / 568 °C. With sufficiently clean biomass and a state-of-the-art design, high availability and acceptable lifetimes of boiler pressure parts can be maintained. When this CHP plant enters commercial operation in January 2020, it will introduce the world’s largest and most advanced 100% biomass fired CFB based power plant. This paper reviews the challenges to build up a bankable EPC solution capable of reaching financial closure and presents the key technical features and performance estimates of the high-efficiency process and state-of-the-art CFB boiler based power plant.Read full article
