Heating Sources For Industrial Ovens

When it comes to industrial ovens, the first two things to consider are the source of the heat and the airflow pattern. The fuel for the heat that’s introduced into the oven can come from a variety of sources including gas, steam, water, electricity, or ultraviolet light. The fuel an oven uses dictates how it works. Gas Ovens There are two types of gas ovens, direct and indirect. In a direct gas oven, a gas or propane burner heats the air that is circulated through the system using a fan. They generally operate at temperatures between 200° F and 500° F, but can reach up to 1000° F. Indirect gas ovens use a gas or propane heat exchanger. A circulating fan pushes air through the heat exchanger to radiation tubes. With this format, the flame is enclosed within a sealed combustion chamber away from the work area. The flame never touches the circulating air. Steam Ovens With a steam oven, water is heated to the boiling point; the resulting steam is used to heat the oven. This is a slower [...]
