Steam-air heat exchanger
Thread Content
Does anyone know which manufacturers are good at producing steam-air heat exchangers?
I’m not sure which one is the best; I’ve used finned radiators from Shandong Xinyuan before
Our company specializes in heat exchangers; the finned tube equipment we use is imported from the United States, and the technology employed is American-based
You can send me your parameters when it’s convenient (wangwei9540@126.com)
It would be best to provide the operating conditions for air and water vapor; if the air is driven by a fan, then an external fin heat exchanger, as mentioned by the people above, would be suitable. If it is driven by a air compressor, the use of external fin heat exchangers is not recommended, as this significantly reduces their service life. It is recommended to use an inboard finned heat exchanger at this time; the greater the temperature difference required for the air, the more significant the advantages become.
It comes from the air compressor. 1. Steam parameters: Superheated steam, with a pressure of 1.27~1.57 MPa (G) and a temperature of 320~350℃ ； 2 Air parameters: oxygen content of 42% (by volume), nitrogen content of 58% (by volume), pressure of 0.6 MPa, temperature of 60°C, and flow rate of 12,914 Nm3/h. Requirement: Use steam to heat the air from 60°C to 200°C℃
For this operating condition, conventional radiators with external fins are not suitable; either tube-only heat exchangers or heat exchangers with internal fins are needed. It is also necessary to determine the material requirements, pressure drop requirements, and other details. If possible, please reply to my message on the platform so that we can discuss this in more detail.
You need two heat exchangers: one (sensible heat – steam changes from superheated to saturated)； Has one (latent heat – steam saturation condensation) been calculated? Can it just heat the air to 200°C?
We also plan to develop an air heat exchanger for pilot testing, using fin design to increase the heat exchange area; we are currently considering this option
TO: 9th floor. The conventional approach involves a preheater that utilizes the latent heat of steam in the first stage, and a gas-to-gas heat exchanger for superheated steam in the second stage. It depends on how the process flow is designed by the person in charge, which is why it was mentioned in the 8th floor message that a detailed discussion is needed.
