Standard Boiler Feed Water Temperature

Performance Test and Efficiency of Boiler | Thermodynamics

In a boiler raising steam, the feed water temperature and steam pressure conditions are different from the standard. A certain amount of heat say H 1 kJ is required for raising a given quantity of steam, say m kg. The same quantity of heat applied to feed water at the standard temperature 100°C produces a mass m e of steam at the standard

The hydrazine (N2H4) must be continuously dosed into the feed water to react with all the oxygen present and to produce a small reserve of hydrazine in the boiler water. The normal level of hydrazine reserve to be maintained in the boiler water is between 0.1 and 0.3 ppm N2H4. 'he chemical reaction with oxygen can be expressed N2H4 +O2=2H2O + N2

The standard warm-up curve for a typical boiler does not increase the boiler water temperature over 100°F per hour. It is not unusual for a continuous minimum fire to exceed this maximum warm-up rate. Consequently, the burner must be intermittently fired to ensure that this rate is not exceeded.

In normal steam heating systems the temperature is even lower at about 160˚F. Chemical treatment of feedwater is introduced through by-pass feeders in the line between the pump and boiler or by means of proportioning pumps directly to the boilers so that feedwater chemicals do not pass through the pump.

Boiler feedwater - Wikipedia

History of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was "blown down". It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler.
