The Difference between Wetback and Dryback Boilers - The Boiling Point

On today's episode of The Boiling Point, Gerald and Ritchie address a topic that WARE gets a lot of questions about—the difference between wetback and dryback boilers.

Chapters:
Dryback 1:41
2-Pass Wetback 8:49
3-Pass Wetback 9:58

A dryback boiler design means that the rear wall is lined with refractory. As an example, Gerald shows us a dryback boiler by Victory Energy that is engineered to optimize water circulation, promote heat transfer, and engineered for long-term performance and reduced maintenance. Using a dryback boiler, you can use up to 10% less fuel.

Wetback boiler designs have a water gap between the furnace and back wall, and all of the heat is generated directly into water. Wetback designs are just as durable as dryback designs, but must have a heat balance in the system.

Be sure to watch the entire video for a very important announcement from WARE.
