Chapter 9 Boilers - NavyB

A boiler is an enclosed vessel in which water is heated and circulated, either as hot water or steam, to produce a source for either heat or power. A central heating plant may have one or more boilers that use gas, oil, or coal as fuel. The steam generated is used to heat buildings, provide hot water, and provide steam for cleaning, sterilizing,

Characteristics of boiler feedwater - Lennte

The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design. If the feed water does not meet these requirements it must be pretreated to remove impurities.

As operating pressures increase, requirements for boiler water composition become more stringent. Water tube boilers experience heat flux rates as high as 250,000 Btu/hour/ft 2. This heat flux rate is far greater than boilers typically experienced when the ABMA limits were established.

Boiler Feed Water - Lennte

Boiler feed water is used to produce steam. The pressure of the steam (0,5 - 100 bar) determines the temperature and energy capacity, but also the quality of the feed water. The general rule is the higher the pressure the more strict the quality of the boiler feed water. Problems caused by impurities in the feed water are:

Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam.

Acceptable phosphate concentrations decrease from 140 mg/L in low pressure boilers to less than 40 mg/L at pressures above 1,500 pounds per square inch (10,000 kPa). Recommended alkalinity similarly decreases from 700 mg/L to 200 mg/L over the same pressure range. Foaming problems are more common with high alkalinity.

Proper Boiler Feed Water Temperature Management | Powerhou

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
