Spiral heat exchangers, how they work and why we use them. Find out how spiral heat exchangers work in this article.
Spiral heat exchangers look like this. We have a flange inlet on the front face with the outlet located at the top, then we have an inlet for another fluid. Also at the top, located at the back behind the end plates, we find two sheets of metal on the inside that wrap around the inside to form a channel through which fluids will now flow through the channel that completely separates the two fluids.
We see the first fluid entering the exchanger and filling the chamber, then flowing around the channel and towards the outlet, while on the other side the second fluid enters from the top flowing around the channel and into the chamber from where the two fluids. they enter and exit at different temperatures, however this type of heat exchanger is not used as often as the design has only one channel for fluid to flow through. plates and even tubes, the exchangers divide the flow into multiple paths making them ideal for installations where sludge-like substances are treated, for example in an anaerobic digester where thick sludge is recirculated through a spiral heat exchanger to maintain a set temperature, which releases methane from the digester into the feed and then rotates an electrical generator..
