The connection between dryers and heat exchangers
Thread Content
Dryers and heat exchangers share one common feature: both can be used to heat materials. So, can a dryer be used as a heat exchanger?
It is not certain whether a dryer can be used as a heat exchanger. Typically, the dryer itself is a combination of a heat exchanger and a heater, and heating is required for drying.
Their uses and operating objects are different. A dryer is designed to remove the liquid components from solids, using methods such as heat exchange and hot air to carry these liquid components out in gaseous form. A heat exchanger is a device used for exchanging heat between hot and cold fluids, and it can be a component of a dryer.
I agree with you, but the issue isn’t its purpose or what it’s used for :) What if a dryer and a heat exchanger are considered as the same type of heat exchange device? Or rather, what if it’s first regarded as a heat exchanger and then as a dryer? (Just a discussion)
The working principle is completely different! ! The object to be heated in a dryer can come into direct contact with the heat source, whereas heat exchangers all have a separation layer Moreover, a dryer is primarily used to remove moisture, while heat exchangers can be used between any types of fluids! !
