Abstract:
There is a large number of different configurations for the combinationof a closed cycle gas turbine (CCGT) system and a high-temperature gas-cooled
reactor (HTGR). Based on the results of a literature survey an overview of
such configurations is presented and a comparison is made for their
appropriateness for a small cogeneration system (<60 MWt) to be used in the
Netherlands. However, most cycles can only be applied for large-scale energy
production or supply heat on a too low temperature level. The direct,
recuperated cycle is the only suitable cycle, while that cycle is a simple
system and shows an acceptable electric and total efficiency. Calculations
were carried out for the co-production of hot water (75-125C and 40-70C) and
for steam (10 bar, 220C). By means of a static model and an optimizer the
feasible efficiencies for different heat demand are determined. The maximum
electric efficiency is 42% for the co-production of hot water and 38% for the
co-production of steam. 28 refs.
