How do enthalpy effect the work of a turbine
WebIt falls out of the flow, and the enthalpy decreases by an amount equal to the latent heat of condensation. The same thing should happen in reverse, when pressure is decreased, more water can join the airflow and this causes its combined total internal energy to increase. WebTurbine steam inlet temperature is another major parameter affecting turbine performance. Reducing steam inlet temperature reduces the enthalpy, which is a function of both the …

The turbine efficiency directly reduces the work produced in the turbine and, therefore the overall efficiency. The inefficiency of the pump increases the enthalpy of the liquid leaving the …
WebThe turbine produces only an enthalpy drop of 156.25 × 2 = 312.5 kJ/kg. If the blade velocity, U, is increased from 250 m/s to 325 m/s and the same enthalpy rise in the compressor is maintained, then the turbine will produce an enthalpy drop of 528.125 kJ/kg, which is in excess of that needed by the compressor. WebA 10% increase in steam pressure will reduce the steam consumption by about 1% in a condensing steam turbine and by about 4% in a back pressure steam turbine. The effect on efficiency for 10% increase in pressure is about 1.5% for a condensing steam turbine and 0.45% for a back pressure steam turbine.
