In high pressure steam plants, small amounts of alkalizing agents are added to condensate, feedwater and boiler water to raise the pH to reduce corrosion. Boiler water chemicals also buffer the

2002-6-25·A method and apparatus for water degasification and distillation in an apparatus having a container for a reservoir of water to be degassed and distilled, a relatively small boiler adjoining the container and having a feed water conduit connecting the container and boiler so that a selected water level in the container will fill the boiler to the same level, a coiled tube condenser within the

Sentry single line sample panels are pre-piped assemblies used to simplify the conditioning of steam, water or non-hazardous process samples. With the addition of cooling water, safe and representative samples can be obtained from individual sampling sites that are remotely located throughout the plant or from a small number of samples in a central location.

The steam reformers operated in parallel are combined to form groups of at least two steam reformers (groups) within which the high purity steam is generated in one of the steam reformers by vaporization of degassed and demineralized water and low purity steam is generated in at least one of the other steam reformers by vaporization of degassed

The fumigating, sterilising, degassing, detoxicating, antiseptic agents and the pharmaceutical compositions based on xenon difluoride and/or xenon trioxide and/or sodium perxenonate and/or a xenon hexafluoride-boron trifluiride adduct are largely used in the form of a solution or in a physiological salt solution or in a gas medium.

a steam/water mixture into steam and water. membrane means (16) for the membrane distillation of degassed water; and outlet means (20) and comprising a certain number of heat exchangers characterised in that said boiler uses an ultrasupercritical steam cycle with four pressure levels (P1, P2, P3, P4) with subcritical fluid intermediate

the boiler should get good fuel efficiency, and, based on both makeup and treatment dissolved solids, the total boiler water dissolved solids should not go so high that carryover, scaling and corrosion are a potential problem. Chlorides may be maintained in the 60-200 range. The chloride concentration is controlled by boiler blowdown.

Brian J. Handy, John C. Greene, and Kenneth Tittle The Estimation of Degassed Acid Conductivity of Steam/Water Samples in Power Plant : The present paper proposes a method of estimating the degassed acid conductivity (DK H) from the measured acid conductivity (K H) and the total carbon dioxide content of a sample.The acid conductivity of a sample is a summation of contributions from a number

2018-8-6·The final steam temperature is 540°C. The low-pressure superheater temperature is ca. 270°C. Make-up water is prepared by ion exchange and thermally and mechanically degassed in two steps in the deaerator. The station has a wet recirculating hybrid cooling system. Figure 2shows a schematic of the water-steam cycle.
