The power electrical generation at Brazil has been more and more discussed and required due to the huge economic and industrial expansion that our Country has been living. One of the methods of electrical power energy generation is the thermoelectric power plants which are capable of transform thermal energy, arising from the combustion chambers, into mechanical energy due to the rotation of the turbine blades and furthermore, transform this mechanical energy at the turbine into electrical energy. Therefore, the thermoelectric power plants have been playing a crucial role in the electric Brazilian sector, mainly as an emergency method of power generation, used when the most standard methods of generation are not capable of support the demand. This paper presents a zero dimensional analyses, through Matlab compiler, of an ideal system composed by combustion chamber, nozzle and turbine applied to a thermoelectric power plant. Three different types of mixture are compared for the combustion chamber: natural gas/air, CH4/N2O and C7H16/O2 yielding as a result 11 products: CO2, CO, H2O, H2, O2, N2, H, OH, O, NO, N. Parameters are adjusted in order to have an optimal electric generation system. Results are shown.
