“…The previous reference employed CFD methods to perform the combustor analysis. Given the numerical cost of CFDs when studying a single gas turbine component, i.e., a low-pressure turbine [40], or when studying combustion related to carbon capture processes [41], CFD methods were not considered as suitable in this work since a whole gas turbine is studied. Other authors have conducted valuable non-CFD numerical studies of gas turbine performance analysis [42] as well as combustion and control processes with biofuels [43].…”

This article shows the effect that biogases obtained from crop residuals from the Andean region have on the performance of a whole medium-sized electrical-generating gas turbine. This technology could be used to supply electricity in energy-depressed areas where biogas is the only accessible resource. The gas turbine worked with higher efficiencies when the obtained biogases were used compared to natural gas. The biofuel that presented the highest efficiencies was the one obtained from wheat residuals alone. Despite this fact, this biofuel would be the most prone to create aerodynamic problems in the stages of the gas turbine. In this work, it was found that the addition of guinea pig manure to different crop residuals created biofuels less prone to create aerodynamic problems in the compression and expansion stages. In particular, the studied biofuel that had the most similar aerodynamic behavior to the design natural gas case was the one obtained from guinea pig manure and quinoa residuals. On the other hand, this biogas presented the lowest efficiencies of the studied biofuels. Despite this fact, this biofuel showed higher efficiencies than the natural gas case. In the gas turbine combustion chamber, all the studied biofuels operated at lower temperatures than the ones with natural gas, even in the high-power range. This would be an important feature for the running of the combustion chamber and the high-pressure turbine superalloys.

“…In 2010, 42% of CO 2 is emitted from eletricity and heat generations which mainly produced by fossil fuel combustion . Due to the resonable cost and operation possibility, postcombustion CO 2 capture is one of the most interesting solutions to reduce the great annual CO 2 emission . An amine absorption column, the conventional approach, was studied in a demonstration coal power plant .…”

CO₂ capture in a multistage CFB: Part II: Riser with multiple cooling stages

A 1 m in diameter and 3.55 m tall fluidized bed riser internally with water tubes, which required six equilibrium stage of riser-sorber for capturing about 95% of CO 2 emitted from a coal power plant, were designed to replace the multisingle risers. At the optimum operating condition, the temperature of the cooling tubes in the bottom, the middle and the top of the riser were kept constant values at 50, 40, and 308C, respectively. The hot water (578C) from lowest exchanger section can be used to preheat the spent sorbent for the regeneration in a downer. The rest of the heat for the regenertion is obtained from the stack gas (100-1308C). This new concept promises to reduce the energy consumption for CO 2 removal from flue gas. The only energy requirement is for pumping fluid and fluidizing particles in the bed.
