A 1000 MWth boiler for chemical-looping combustion of solid fuels – Discussion of design and costs

Open access
Lyngfelt, Anders, Leckner, Bo·2015·Applied Energy

Abstract

More than 2000 h of solid-fuel CLC operation in a number of smaller pilot units clearly indicate that the concept works. A scale-up of the technology to 1000 MWth is investigated in terms of mass and heat balances, flows, solids inventories, boiler dimensions and the major differences between a full-scale Circulating Fluidized-Bed (CFB) boiler and a Chemical-Looping Combustion CFB (CLC–CFB). Furthermore, the additional cost of CLC–CFB relative to CFB technology is analysed and found to be 20 €/tonne CO2. The largest cost is made up of compression of CO2, which is common to all capture technologies. Although the need for oxygen to manage incomplete conversion is estimated to be only a tenth of that of oxy-fuel combustion, oxygen production is nonetheless the second largest cost. Other significant costs include oxygen-carrier material, increased boiler cost and steam for fluidization of the fuel reactor.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
