Regulating Characteristics Analysis of Boiler Feed-water


Regulating steam temperature in drum boilers by means …1/9/2013 · The object of study was an automated system designed to control the feed of coolant water to the superheater tract of a TP-87 steam boiler used in a power plant. The dynamic characteristics of the superheaters were determined in relation to the channels used to transmit the control actions. It was established that a corrective system needs to be designed to automatically regulate the Characteristics of boiler feedwater - LenntechCharacteristics of boiler feed water. Characteristics of boiler feed water. Water absorbs more heat for a given temperature rise than any other common inorganic substance. It expands 1600 times as it evaporates to form steam at atmospheric pressure. The steam is …

Modeling and simulation of a natural circulation water …Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are centrifugal pumps.
