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.
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. Some Dryback designs can be just as durable as wetback designs, but must have a heat balance in the system.
