Advanced Medium-Large Steam Cycles
(2024) 4th IEEE International Conference on Electrical, Computer, and Energy Technologies, ICECET 2024 In International Conference on Electrical, Computer, and Energy Technologies, ICECET 2024- Abstract
Currently facing the problems of security of supply and higher electricity prices in southern Sweden, a medium-large power plant is considered to be built. To prepare for the possible outcome, a study of different cycle configurations was conducted. The study analyzed a 500 MWeldistrict heating mode power plant based on the Avedare power plant in Denmark, a single reheat Rankine cycle with a heat recovery unit in the feed water heater chain. Implementing boiler feed pump turbines (BFPT) into the cycle was done to study the effect on the efficiency. To improve the single reheat cycle, a second reheat was included and studied. Due to its high superheat of steam at extractions, alternate solutions were implemented. These included: (1.) a... (More)

Implementing boiler feed pump turbines (BFPT) into the cycle was done to study the effect on the efficiency. To improve the single reheat cycle, a second reheat was included and studied. Due to its high superheat of steam at extractions, alternate solutions were implemented. These included: (1.) a boiler feed pump turbine to provide extraction steam, and (2.) desuperheaters, acting as heaters at the district heating condenser extractions. Reheat pressures as well as temperatures after feed water heaters were optimized for highest efficiency during district heating operating mode. Adding a boiler feed pump turbine with the feed from IP-LP crossover and drain into the cold condenser showed the highest electric efficiency but the lowest district heating efficiency. The next best electric efficiency was shown by the standard double reheat cycle. The addition of a boiler feed pump turbine providing extractions, lowering superheat at the extractions, showed worse efficiency as a base but was matched with the base double reheat cycle by the addition of desuperheaters.
