Utilization of Low Temperature Heat in Coal based Power Plants
MetadataVis full innførsel
Carbon Capture and Storage aims at capturing and storing carbon emissions from large point sources underground. One of three main ways of implementing CCS is in coal based power plants is the pressurized oxy-combustion, an advanced form of oxy-combustion. There are different approaches in designing the heat cycle with CCS. Included in the design is the acid condenser, a heat exchanger which utilizes the low temperature and latent heat of the flue gas for preheating purposes. The objective of this master thesis is to determine the maximum amount of power generated by a CO2 power cycle using the mentioned heat available in the acid condenser. This alternative will be compared to other means of utilizing the low temperature heat, i.e. for preheating purposes in the primary steam cycle.
