Boiler Water Conductivity is the measurement of the dissolve solids, dissolved gases, and suspended solids within the boiler water. Conductivity is used to monitor the boiler cycles of concentration. This is the most important measurement when performing boiler water testing.
CONDUCTIVITY CONTROL IN THE BOILER • Blowdown – two types with two distinct functions • Surface blowdown • Small amount of boiler water drawn off near surface continuously or intermittently • Function is to control concentration of dissolved solids; provide correct boiler water chemistry • Bottom blowdown

Raw water Impurities and its impact on boiler: 1.Total Alkalinity: In raw water, total alkalinity primarily covers bicarbonate. A small amount of carbonate might also be present. Hydroxide ions do not exist in raw water. Total alkalinity in raw water is important since it
Conductivity control is important for minimizing the mineral level in the boiler by replacing process water with fresh water. This removal of water is referred to as blowdown. While blowdown is an important process, excessive blowdown should be prevented to avoid wasting water and energy.

Improve boiler water quality by measuring the conductivity and purity of the liquid in your steam boiler and feedtank with a Spirax Sarco Conductivity Meter. Welcome to the Beta version of the Spirax Sarco website intended for final customer testing. During this beta phase, we will be fine tuning the website before the launch of the new website.
Conductivity Meters The amount of dissolved solids in boiler water can be directly related to its conductivity level. Therefore, by measuring the conductivity of a liquid, the …
The specific conductance of a sample, measured in microsiemens (µS) or micromhos (µmho), is proportional to the concentration of ions in the sample. When boiler water is carried over in steam, the dissolved solids content of the boiler water contaminates the steam, and steam sample conductivity increases.
Effects of Carryover Boiler water carryover can cause deposits to form in valves, heat exchangers, turbines, and superheaters. If deposits are significant, heat transfer and/or turbine efficiency may be reduced. Additionally, carryover can strip away the protective ...

Boiler Water Tests What items are used for Boiler Water Tests? The most common items used for testing chemicals are listed on this page. The most popular items are hardness test kits, sulfite test kits, and conductivity meters. Where can I buy Boiler Water Tests for my boilers? Test kits are typically difficult to locate locally.
Boiler scale creates a problem in boiler operation because the different types of scale formed all posses a low degree of heat conductivity. The presence of scale is, therefore, equivalent to spreading a thin film of insulation across the path of heat transfer from the high temperature gasses to the boiler water.
Able to operate well above conditions of conventional sensors, the Boiler Conductivity Sensor can directly measure samples up to 250 psig (17 bar) at 392° F (200° C). The Boiler Conductivity Sensor is used with the versatile Thornton M300 Transmitter which provides display, analog outputs and alarm relays plus on-off and PID control capability.

12/15/2010 · Objectives of the Boiler Water Testing 1)To monitor the condition of the boiler water. 2)To control the chemical dosing of the boiler. 3)To maintain the boiler in healthy state, around any possible seawater contamination. The first stage in the boiler water testing is to collect feed water sample from the boiler concerned.
Sometimes, conductivity measurements are linked with other methods to increase the sensitivity of detection of specific types of ions. For example, in the boiler water technology, the boiler blowdown is continuously monitored for "cation conductivity", which is the conductivity of the water after it has been passed through a cation exchange ...

Boiler Feedwater. Boiler feedwater is then treated in the deaerator to remove dissolved gases (mainly oxygen and carbon dioxide) as these dissolved gases would otherwise cause corrosion in the boiler systems, and a final chemical treatment agent is applied to further remove oxygen after the deaeration (BETZ, 1991).
