What industrial oven provides the best BTU?

The industrial oven that provides the highest BTU is the box oven. Box ovens are large, enclosed ovens that use natural gas or electricity to heat the air inside. This type of oven is often used for industrial applications, such as metalworking, baking, and drying. The air inside a box oven can reach temperatures of up to 2,000 degrees Fahrenheit, allowing it to generate the highest BTU.
