The ideal, simple and basic power cycles (Carnot Cycle, Brayton Cycle, Otto Cycle and Diesel Cycle) and ideal combustion are presented in this one-hour webinar.
In the presented power cycles analysis, air is used as the working fluid. However, for the purpose of the Brayton Cycle analysis, in addition to air, argon, helium and nitrogen are considered as the working fluid.
For each power cycle, a T - s diagram, a p - V diagram, where applicable, and power cycle major performance trends (thermal efficiency, specific power output, power output, specific fuel consumption based on fuel higher heating value (HHV) and ideal and complete combustion conditions, oxidant to fuel ratio and both weight and mole basis combustion products) are plotted in a few figures as a function of compression pressure ratio, turbine inlet temperature and/or final combustion temperature, working fluid mass flow rate and/or specific mass flow rate.
In order to make it easy to follow the presented combustion analysis of the ideal power cycles, this webinar includes a combustion analysis that uses standard air as the oxidant when burning six different fuels at stoichiometric conditions and one fuel (methane - CH4) at oxidant rich conditions (stoichiometry > 1). Also, the combustion analysis presents how oxidant preheat temperature values have an impact on the flame temperature.
For combustion analysis, the technical performance at stoichiometric and oxidant rich conditions (stoichiometry > 1) is presented knowing the enthalpy values for combustion reactants and products, given as a function of temperature. For each combustion case considered, combustion products composition on both weight and mole basis, flame temperature, oxidant to fuel ratio and fuel higher heating value (HHV) are presented in tabular form and plotted in a few figures.It should be noted that this webinar does not deal with costs (capital, operational or maintenance).Webinar Lessons
