An EU initiative for future generation of IGCC power plants using hydrogen-rich syngas: Simulation results for the baseline configuration

Mansouri Majoumerd, Mohammad; De, Sudipta; Assadi, Mohsen; … - In: Applied Energy 99 (2012) C, pp. 280-290

current development. The integrated gasification combined cycle (IGCC) power plant with pre-combustion carbon capture is a … capture is estimated to 36.3% (LHV). The results confirm the fact that a significant penalty on efficiency is associated with … the capture of CO2. This penalty is 21.6% relative to the IGCC without CO2 capture, i.e. 10.0% points. Estimated …

The effect of firing biogas on the performance and operating characteristics of simple and recuperative cycle gas turbine combined heat and power systems

Kang, Do Won; Kim, Tong Seop; Hur, Kwang Beom; Park, … - In: Applied Energy 93 (2012) C, pp. 215-228

We investigated the influence of firing biogas on the performance and operating characteristics of gas turbines. Combined heat and power systems based on two different gas turbines (simple and recuperative cycle engines) in a similar power class were simulated. A full off-design analysis was...

Performance evaluation of integrated gasification solid oxide fuel cell/gas turbine systems including carbon dioxide capture

Park, Sung Ku; Ahn, Ji-Ho; Kim, Tong Seop - In: Applied Energy 88 (2011) 9, pp. 2976-2987

than the cathode heat exchange scheme. The impact of CO2 capture was investigated in both the IGCC and IG-SOFC/GT systems …, and the penalties in power output and efficiency due to pre-combustion CO2 capture were found to be milder in the IG …-SOFC/GT systems than in the IGCC. An IG-SOFC/GT system adopting oxy-combustion-based CO2 capture was proposed, and its thermal …

Compressor washing economic analysis and optimization for power generation

Aretakis, N.; Roumeliotis, I.; Doumouras, G.; … - In: Applied Energy 95 (2012) C, pp. 77-86

The deregulation of the energy market has created an additional incentive for gas turbine plants operators to minimize and control performance deterioration with respect to the economical aspects of the plant. The most prevalent deterioration problem is compressor fouling, which has a...

Gas turbine sensor validation through classification with artificial neural networks

Palmé, Thomas; Fast, Magnus; Thern, Marcus - In: Applied Energy 88 (2011) 11, pp. 3898-3904

Modern power plants are all strongly dependent on reliable and accurate sensor readings for monitoring and control, thus making sensors an important part of any plant. Failing sensors can force a plant or component into non-optimal operation, cause complete shut-down of operation or in the worst...
