The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F.

Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.

The shell is heated by low-pressure (waste) steam at 0.4–0.5 MPa and at 160 °C, which condenses inside the inter-tube space. Brown coal with a particle size of less than 10 mm enters the tubes with a diameter of 100 mm on the upper side of the shell, passes through the tubes, and is …

The exact ratio of sodium to dissolved solids in the boiler water and consequently in the steam can be determined for each plant but is approximately 1:3 for most plants (i.e., for each 0.1 ppm of sodium in the steam there is approximately 0.3 ppm of dissolved solids present).

State 2 is fixed by the pressure p 2 = 6.0 MPa and the fact that the specific entropy is constant for the isentropic compression (s 1 = s 2 = 0.592 kJ/kgK for 0.008 MPa). For this entropy s 2 = 0.592 kJ/kgK and p 2 = 6.0 MPa we find h 2, subcooled in steam tables for compressed water (using interpolation between two states). h 2, subcooled
