Cation conductivity monitoring: A reality check
Efficiency factors in natural gas fired steam boilers
High conductivity or contamination of the boiler feedwater can create other problems such as drum level instability and foaming. This can result in high or low-water alarms and an increase in the carryover of moisture droplets into the steam header since the moisture separator of the drum cannot handle the resultant carryover.
Operation of Boiler and Conductivity in Drum Water and
Dec 23, 2009 · Probable reasons. Boiler water tube leakage; Boiler blowdown is in progress; Boiler drain valves or blowdown valves passing; The corrective action. Confirm tube leak, check conductivity before cation column and dose caustic soda through HP dosing system and maintain conductivity; Check drain valves and blowdown valves for any leak and attend
j No value given because steam purity achievable depends on many variables, including boiler water total alkalinity and specific conductance as well as design of boiler, steam drum internals, and operating conditions (see footnote f). Because boilers in this category require a relatively high degree of steam purity, other operating parameters must be set as low as necessary to achieve this high purity for …
temperatures are the highest, the fire-side oxidation and corrosion potential are the greatest, and steam side scale formation is the most rapid. It is for these reasons that the actual life is about half that of the rest of the boiler, about fifteen years or so. GAS PHASE OXIDATION
Sep 02, 2019 · A key issue with high conductivity in boiler water is that operational issues such as scaling can occur, which is a buildup of solid material in the boiler. When this occurs, the boiler becomes less efficient and increases the fuel consumption of the unit.
Boiler Water Conductivity Measurement Fundamentals
Feb 24, 2016 · The main aspects are the great temperature difference and high pH. An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for …
