What standards should the water quality of heat exchangers meet?
Thread Content
Experts, I’m facing a project where the water quality report provided by the client is shown in the diagram. The client states that this water quality is not suitable for use in boiler systems, and they are asking whether it’s possible to use heat exchange to lower the water temperature, so that the client can then treat the water quality. What are the requirements of our heat exchangers regarding this type of water quality? Specific to this project, can the water quality report provided be used directly for heat exchange in the heat exchanger, so as to facilitate subsequent water quality treatment? Thank you all for your positive responses; I’ve learned a lot from this!
Low water temperature when injecting it into the boiler may lead to oxygen presence in the boiler. In your case, it’s necessary to first lower the temperature, then treat the water quality, heat it up, and finally inject water – which is a waste of energy... As for water quality... in the past, condensed steam water was used directly for replenishment...
In accordance with GB50050-2017 \"Design Code for Industrial Circulating Cooling Water Treatment\" and SH3099-2000 \"Quality Standards for Water Supply and Drainage in Petrochemical Industries\", the water quality provided by Party A is suitable for use in heat exchangers, and it is of better quality than that of ordinary circulating water; the specific parameters meet the relevant requirements specified in the standards
