The following tables of the properties of steam are taken directly from Chapter 5.5.3 of the Heat Exchanger Design Handbook, 1986, by C. F. Beaton. The tables in this section are reprinted, with permission, from NBS/NRC Steam Tables.
From the saturated steam table mentioned above, one can see that it takes 419 kJ/kg (180 Btu/lb) to heat water from 0°C to 100°C (32°F to 212°F). This is the enthalpy of water (hl). It takes an additional 2,257 kJ/kg (970 Btu/lb) to create steam at atmospheric pressure (100°C or 212°F).

Steam condensing turbines - PBS. The back-pressure on the mercury turbine is fixed by the steam boiler pressure; only a small vacuum pump is needed, as there is no air or other gas in the mercury system. Power plants designed by William Le Roy Emmet were constructed by General Electric and operated between 1923 and 1950.
Table 13-5 provides a typical calculation for determining the fuel savings achieved in a heat recovery system using a low-pressure flash tank and heat exchanger. Figure 13-3 can be used to determine the quantity of flash steam recoverable from a flash tank. Table 13-5.
Introduction to Steam and Humidity What is Steam? In engineering, steam, most often refers to vaporized water.It is a chemically pure, invisible gas (not a mist) which at standard atmospheric pressure (1 atmosphere) has a temperature greater than 100 degrees Celsius, and occupies about 1,600 times or more the volume of the same mass of liquid water.

Factors Of Evaporation Example.-Suppose that a cylinder boiler is to be proportioned for an evaporation of 500 lbs. of water per hour, at a pressure of 75 lbs., the temperature of the feed-water being 80°. The equivalent evaporation will be 1.17 times 500, or 585 lbs., and the grate-surface 585 divided by 75, or 7-8/10 square feet.
