Boiler piping

May I ask: For a 15-ton boiler, does the feed water enter the economizer first and then the deaerator before reaching the boiler, or does it enter the economizer first, then the deaerator, and finally the boiler?
Advanced deaerator! Coal economizer at the back!
For any boiler, the water must first be deoxygenated before entering the boiler through the economizer! This should be beyond doubt! :D
Using exhaust gas for heating is energy-saving; using it solely for deoxygenation is somewhat wasteful. Moreover, passing the deoxygenated water through a economizer also helps to prevent corrosion, so the water is first deoxygenated, then sent through the economizer before entering the boiler
It is recommended that the poster should communicate more with professionals such as maintenance staff and water treatment specialists.
Deoxygenation should be carried out first, before proceeding to the economizer
Feeding water into the deaerator prevents oxygen corrosion of boiler equipment, ensuring its service life
Could you please clarify what the assumption regarding \"water supply\" is, or provide the quality table (DS, etc.)? Last edited by wwyyhbmt on 2008-2-24 02:06.]
In boiler deaerators, the feed water is first deaerated before entering the boiler through the economizer; however, small boilers generally do not achieve good deaeration results, so such deaerators are usually not used in them.
Deoxygenation is carried out to reduce oxidative corrosion in the heated pipes and vessels within the boiler; the economizer is also one of the heated devices, and of course the water that enters it must first be deoxygenated. Additionally, from a material perspective, this approach allows for better utilization of materials of lower quality.
Feeding water into the deaerator prevents oxygen corrosion of boiler equipment, including the economizer; therefore, it should be fed first into the deaerator

The cast-iron economizer can be used as an economizer first... Your 15-ton boiler probably uses a cast-iron economizer
Can a cast-iron economizer be fed with water that has not had oxygen removed? Isn’t there a risk of oxidation of the pipes? Please advise!
