Heat recovery steam generator [HRSG] | Tube Fin Burn Out

A 20 bar saturated steam Heat Recovery Steam Generator [HRSG] had recently been commissioned at a paper recycling plant. The HRSG was installed behind a 6 MW gas turbine and fitted with a duct burner to boost the boiler's output. The HRSG was a forced circulation unit fabricated from horizontally oriented spiral wound finned tubes.

Boiler water treatment - Lenntech

The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

Water Handbook - Steam Purity | SUEZ

In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.

How the boiler circulating pump works. - YouTube

Aug 28, 2019 · The reason for using bent tubes is to avoid thermal stresses. The topmost three drums are connected by circulating and equalizing tubes. Circulating tubes are used to circulate water equally among the three drums and equalizing tubes to maintain an equal amount of steam in the drums. The first drum is connected with a steam stop valve.
