relationship between boiler main vapor temperature and pressure

marcet boiler - SlideShare

Feb 05 2014 · Besides that this experiment was also done to demonstrate the vapor pressure curve. The market Boiler was used for this experiment. When the pressure increases the temperature also increases. Therefore the relationship of pressure and temperature is directly proportional. The derived formulae and the data were used to calculate the slope.

Vapor Pressure | Chemistry for Non-Majors

Vapor pressure is dependent upon temperature. When the liquid in a closed container is heated more molecules escape the liquid phase and evaporate. The greater number of vapor molecules strike the container walls more frequently resulting in an increase in pressure. The Table below shows the temperature dependence of the vapor pressure of three liquids.

Boiler Temperature - an overview | ScienceDirect Topics

In the simulation we change the inlet temperature of the high-pressure turbine (or the outlet temperature of the boiler) between 400°C and 600°C in steps of 10°C. For each temperature the pressure is changed from 10 to 15 MPa in steps of 1 MPa. The at the inlet of the low- turbine is 20% of that of the high- turbine.
