Abstract
Power generation is a subject much discussed today. There is still concerns about pollution from fossil fuels and a non-renewable characteristic of such fuels. With such growth it becomes necessary to study and understand new technologies and new sources of energy generation. Here, simulations were performed combining a linear-fresnel concentrated-solar- power system with gas extracted from a landfill to feed a 16 MWe thermoelectric power plant based on the estimated stock of gas by LandGEM model. The technology of choice was Integrated Solar Combined Cycle System (ISCCS). The calculation was carried out in a simplified way in order to obtain an estimate of the amount of gas needed to maintain the energy demand of the plant. The required flow rate was 34475t / year of methane required in the brayton cycle and 3209t/year by an auxiliary burner in bottoming Rankine Cycle. The solar component was 18% of heat needed for the Rankine system. The efficiency of the combined cycle obtained was about 42%.
