Brazil has an increasing production of municipal solid waste that, allied to the current waste management system, makes the search for alternatives of energy recovery essential. Thus, this work aims to study the incineration of municipal solid waste and the electricity production through steam cycles evaluating the influence of municipal solid waste composition. Several scenarios were studied, in which it was assumed that some fractions of municipal solid waste were removed previously. The municipal solid waste generated in Santo André city, São Paulo State, Brazil, was adopted for this study. Simulation results showed that the removal of organic matter and inert components impacts advantageously on the cycle performance, improving their parameters in some cases; in addition, there is the possibility of reusing the separated fractions. The separation of some recyclables, as plastic material, showed disadvantages by the reduction in the electricity generation potential owing to the high calorific value of plastics. Despite the high energy content of them, there are other possible considerations on this subject, because some plastics have a better recovery potential by recycling.
巴西城市固体废弃物的产量不断增加，再加上当前的废弃物管理系统，使得寻求能源回收替代方案变得至关重要。因此，本研究旨在通过蒸汽循环研究城市固体废弃物的焚烧及电力生产，评估城市固体废弃物成分的影响。研究了几种情景，其中假设预先去除城市固体废弃物的某些部分。本研究采用了巴西圣保罗州圣安德烈市产生的城市固体废弃物。模拟结果表明，去除有机物和惰性成分对循环性能有有利影响，在某些情况下会改善其参数；此外，分离出的部分有再利用的可能性。分离一些可回收物，如塑料材料，由于塑料的高热值导致发电潜力降低，显示出不利之处。尽管它们的能量含量很高，但在这个问题上还有其他可能的考虑因素，因为一些塑料通过回收有更好的回收潜力。
