摘要
Carbon capture and storage (CCS) technology based on oxy-fuel method seems to be a promising technology which can enable production of electricity and heat in a zero emission fossil fuel power plants. One of the interesting CCS oxy-fuel technologies is NGCC system incorporating an oxy-fuel combustor producing a high-pressure superheated steam mixture composed mainly of H(2)O and CO(2), which is then expanded in a series of advanced turbines.
A very beneficial part of the system could be a separation steam generator. It ensures separation of steam from CO(2) by condensation process in a primary circuit at elevated pressure. The liquid condensate is led back to the combustor, while the gas leaves the system for further processing. Latent heat of condensation is transferred to a secondary circuit to raise low-pressure steam.
Condensation in the presence of non-condensing gas is technical problem which determines design of the separation unit. Thus an investigation of local heat transfer coefficients has been conducted at various conditions. For this purpose an experimental apparatus has been built and mathematical model has been proposed. The final step of the research is 30kW pilot unit design, fabrication and performance testing
