PDF Boiler - Fundamentals and Best Practices

Steam Production When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100°C (180°F) This rise in temperature can be detected and is called Sensible Heat

Find the work and heat transfer in the Rankine Cycle

"Consider a steam power plant operating on the simple Rankine cycle. The steam leaves the boiler at 3.0 MPa, 400°C. The turbine exhausts to the condenser operating at 10 kPa. Using the data above, find the specific work and heat transfer in each of the ideal components and the cycle efficiency." I know that (assuming the turbine is adiabatic) the 1st law reduces to (W/m) = h(in) - h(out

For a steam circuit as shown previously, the boiler produces superheated steam at 50 bar and 400oC. This is expanded to 3 bar with an isentropic efficiency of 0.9. The exhaust steam is used for a process. The returning feed water is at 1 bar and 40oC. This is pumped to the boiler. The water leaving the pump is at 40oC and 50 bar.

Heat transfer will be different in one-pipe and two-pipe systems, and depend on steam pressure or temperature. For a one pipe system, only the heat of vaporization is transferred, and pressure is generally only slightly above atmospheric. If we say 110 kPa (102.3 °C), the heat content would be 2250 kJ/kg.
