List of literature used



To consolidate theoretical knowledge on the course "Heat and mass exchange" a course work was carried out: "Calculation of a steam-water heater"

In the design calculation of the heat exchanger, 3 tasks were solved:

1. thermal;

2. hydraulic;

3. mechanical.

In the thermal calculation, the following were determined: physical parameters of water and water vapor; average logarithmic temperature difference: for the first zone, for the second zone; amount of heat transferred by steam to water for two heat exchange zones Q = 14485.16 kW; steam mass flow Dp = 6.73 kg/s; Heat transfer factors: for water, for steam; heat transfer coefficient: for the first zone: for the first zone:, for the second zone, the heating surface was F = 90 m2. Total number of tubes n = 301 pcs, their length L = 3 m.

The hydraulic calculation determined: the full head necessary for the movement of water through the apparatus, which amounted to, as well as the power necessary for the movement of water through the heater N = 0.36 kW, the dimensions of the nozzles: for water: Fpat = 0.05 m2, dpat = 0.25 m, for steam inlet: Fpat = 0.07 m2, dpat = 0.23 m, for condensate output: Fpat = 0.002 m2, dpat = 0.05 m, for air pumping: Fpat = 0.0003 m2, dpat = 0.02 m.

In the mechanical calculation for strength, the following were determined:

design pressure Pp = 11.1 MPa

number of bolts z = 30 pcs, their diameters db = 18 mm

flange height h = 55 mm

design force on bolt Rb = 70 kN
