Numerical Investigation of Power Plant Operates with Super critical Pressure Boiler
Numerical investigations were made of heat transfer to supercritical water flowing in a boiler vertical tube. A comprehensive set of data was obtained for pressures from 22.09 MPa to 25 MPa, mass velocity 250-400 kg/m2s, the results are bulk temperatures from 345°C to 445°C, heat fluxes from 150 to...

| description | Numerical investigations were made of heat
transfer to supercritical water flowing in a boiler
vertical tube. A comprehensive set of data was
obtained for pressures from 22.09 MPa to 25
MPa, mass velocity 250-400 kg/m2s, the results
are bulk temperatures from 345°C to 445°C, heat
fluxes from 150 to 800 kW/m2, tube diameter was
48 mm. The steady thermal model for cross
section of water wall tube was established. Heat
flux and temperature of working fluid are
determined by using Fortran computer program
at each section of the tube length. The heat
transfer coefficients show behavior depending
upon the heat flux. the power of plant, boiler
efficiency, and plant efficiency was determined at
different mass velocities, we found that the boiler
and plant efficiencies increasing with the
increasing of power of plant. The comparison
between this investigation results and the results
of other sources, we found good agreement
between literatures references and numerical
results of this study. |
