Abstract:
The energy crisis in 2001 highlighted the need for expansion of investments in the Brazilian power sector. Depending on the hydraulic crisis, there was a government incentive for electricity generation from the drive of Thermoelectric. In 2013, the Brazilian electricity sector issued about 115 kg of CO2 to produce 1 MWh. In Brazil, currently about 41 thermoelectric plants use fuel oil and diesel oil use in 2122. The fuel used in the thermoelectric engine studied are like, diesel and fuel oil containing low-sulfur. In this sense, the objective of this research is to analyze the issues in a Thermal Power Plant to compounds formed in combustion engines: CO, CO2, SO2, NO, NOx having as comparator emissions from residual O2 combustion. Experiments were performed on a scale of increasing and decreasing the engine power 8.45 MW of generating capacity of 1 MW ranges. The data of emissions of gases in the engine were collected through the analyzer of exhaust gas equipment and will be compared with data from the engine conditions in operation through the UTE monitoring system that enables stores data and visualization systems that make up the engine in real time. The comparative study with the Thesis Costa (2007) in a 150 kW engine installed on Thermogeneration UFCG laboratory shows that rising diesel consumption with power lift according to the literature. Pointing the trend of reducing polluting fuel consumption, diesel by a cleaner fuel source, natural gas in engines of 8.45 MW of thermoelectric aimed at reducing emissions of primary pollutants from combustion due to the use of dual mode, operating with diesel and natural gas in the thermoelectric engines, maintaining the original characteristics of the engine, good performance and increasing energy efficiency.
