Deoxygenated water and boiler water
Thread Content
Is deoxygenated water the same as boiler water? What is the role of deoxygenated water in sulfur recovery systems?
Simply put, it’s the same. The deoxygenated water used in sulfur recovery units is the water (used for gas generation) employed in the sulfur production furnace and the waste heat boilers of the flue gas furnace.
Deoxygenated water has an oxygen content of less than 15 ppm; it is fed into boilers to generate steam. Boiler water is deoxygenated water to which phosphates are added, in order to remove ions such as calcium and magnesium from the water
Put simply, deoxygenated water can be used as boiler feed water, but its uses are limited to just one. Boiler water can be supplied by deoxygenated water with added chemicals. Some design institutes may habitually combine the two in a particular project; in reality, it is the same system
The main condensate water from the turbine is pressurized by the condensate pump, then flows through the low-pressure heater before entering the deaerator. After thermal deaeration, the deaerated water is heated in the high-temperature heater before being fed into the boiler. There is a misunderstanding regarding the third floor: deoxygenated water is already treated water that serves as make-up water or condensate from the condenser, and it can be used directly as boiler water for heating
Deoxygenated water generally refers to boiler water from which oxygen has been removed.
The external pipe gallery of our plant was designed by the Ningbo Institute; it is referred to as medium-pressure boiler feed water. However, the internal part of the plant was designed by the Fushun Design Institute, and it is called deaerated water. It is essentially a type of water, primarily used for reducing the temperature and pressure of steam.
Boiler water and deoxygenated water are different; deoxygenated water is the boiler feed water, which is soft water that has been treated to remove oxygen, while boiler water is the water that results from boiler feed water passing through a boiler used to generate steam. Boiler water contains substances such as corrosion inhibitors and scale preventatives, and it has a higher level of solids.
Boiler feed water is generally softened water obtained by adding deoxygenated water to remove certain scale-forming components from the water; deoxygenated water is simply water that has been heated and deoxygenated~
The answer is incorrect. Let an expert come out and explain.
Deoxygenated water has an oxygen content of less than 15 ppm; it is fed into boilers to generate steam.
