Heat recovery of air at the compressor outlet before it enters the air cooling tower.
Thread Content
I’m seeking advice from everyone – are there any companies that have carried out modifications to recover the heat from the compressor outlet and use it to heat polluted nitrogen gas or water? I’d like to discuss the feasibility of this approach. You can add V; the name will then be Hai Chuan Ming.
Most of the heat generated by the air compressor is removed by the intercooler and the water in the air-cooling tower; it is therefore advisable to find a way to recover the heat from that water, as this is a more direct approach. For reference.
Thank you for your reply. The air temperature before it enters the air-cooled tower is around 90 degrees, and there is no heat exchanger installed on the final stage of the air compressor. I’m now considering recovering part of this 90-degree heat before sending it to the air cooling tower; I’m not sure if there are any existing successful examples for this.
There is a noun called “waste heat” – is heat energy that has no value for recycling understood as “waste heat”? If one can reach the limit, they can be considered an expert. Wish you success!
For waste heat recovery at the outlet of the final stage of the air compressor, the negative effect of contaminated nitrogen increasing resistance must be taken into account~
What is the relationship between waste heat recovery in air compressors and polluted nitrogen? ? ? I’m confused; please clarify.
Think more broadly; I want to heat the water, not the nitrogen gas.

Heated to over 50 degrees, it is fed into the city’s heating network.
This approach is feasible: another air-cooling tower can be installed in front of the existing one, with a dedicated pipeline using \"special water for urban heating networks\" to supply it. The load on the chillers for the air-cooled towers in the original design at the back can be **reduced**. However, the relevant water quality requirements must be met, for reference only.
An increase in the resistance due to nitrogen contamination indicates a slight rise in the overall energy consumption of the air separation unit~
