Thermal Conductivity of Water and Steam - Nuclear …

2019-10-30 · Thermal Conductivity of Water and Steam. Water and steam are a common fluid used for heat exchange in the primary circuit (from surface of fuel rods to the coolant flow) and in the secondary circuit. It used due to its availability and high heat capacity, both for cooling and heating. It is especially effective to transport heat through vaporization and condensation of water because of its

High Conductivity Feed Water = "high Conductivity …

High Conductivity Feed Water = "high Conductivity Steam"? - posted in Industrial Professionals: Hello gents My question is this; if I have high conductivity in the feed water to a steam generator (850 - 1000 µS/cm) will that automaticly translate to high conductivity in the steam produced? I know we'd normaly not talk about conductvity in steam but I hope you'll understand what I mean.

BOILER BLOWDOWN CONDUCTIVITY CONTROLLER …

2015-12-30 · The Model 250 Series boiler blowdown controller is intended to measure and control the surface blowdown water of boilers. By measuring the conductivity, the controller is capable of holding the boiler water conductivity within 200 µS/cm. This control results in considerable fuel savings by preventing excessive blowdown.

How to Treat High Conductivity in Water Sciencing

High conductivity is related to high TDS (total dissolved solids) concentration in water, amount of dissolved mineral salts in water. Conductivity meters that measure conductivity also aim to measure the TDS of the sample for producing the result. For reducing the TDS of water on a domestic or an industrial level, you must seek help from an expert.

Overcoming high conductivity in process condensate

Condensate from the refinery steam users is collected in the High Grade (HG) and Low Grade (LG) condensate systems and returned to the power plant, where it is mixed with FED and flows into the boilers as boiler feed water (BFW). Conductivity meters are installed on the condensate return headers to detect leaks from the seawater cooling systems
