We wish to consider the work that can be obtained by carrying out the following reactions in a steadyflow process: H 2 ( g )
We wish to consider the work that can be obtained by carrying out the following reactions in a steadyflow process:
Hydrogen is burned completely with the theoretical amount of air, both initially at kPa and in an adiabatic reactor at constant pressure. If the flue gases are cooled to at a constant pressure of kPa by the transfer of heat to a boiler to generate superheated steam at MPa and what is the work that will be obtained from a simple powerplant cycle operating as follows?
A turbine expands the steam from the boiler to MPa. A condenser at MPa delivers saturated liquid water to a pump that returns the water to the boiler. The total enthalpy and entropy changes for the reversible cooling of flue gases to are and Take as a basis mol of burned to form the flue gases and
Make a thermodynamic analysis of the process. Represent your results in a table including and as percentage of Evaluate the thermodynamic efficiency of the process.
PS: There is no heat transfer between surroundings and the boiler.
