Q1: Why should industrial dryer exhaust heat be recovered?

Answer:

Industrial dryers often discharge large volumes of hot exhaust air containing valuable thermal energy.

Examples include:

﹡Food dryers 

﹡Spray dryers 

﹡Biomass dryers 

﹡Paper dryers 

﹡Chemical dryers 

Recovering heat from dryer exhaust can:

﹡Reduce energy consumption 

﹡Improve dryer efficiency 

﹡Lower carbon emissions 

﹡Reduce operating costs

Q2: What challenges exist in dryer exhaust heat recovery?

Answer:

Dryer exhaust heat recovery can be challenging because exhaust air may contain:

﹡High humidity 

﹡Dust particles 

﹡Organic substances 

﹡Corrosive components 

Condensation and fouling can reduce heat exchanger performance.

Wide-channel pillow plate heat exchangers are suitable for these applications due to their anti-fouling design and corrosion-resistant materials.
