Regenerative Furnace

TECO regenerative furnaces are characterized by their fuel efficiency and low emissions while producing high-quality glass. Regenerative furnaces come in two types:

Side-Port Furnaces

TECO is a major designer/builder of side-port furnaces. The side port furnace is primarily used for the upper capacity range applications, 300 to 1,000 metric tons per day, as are encountered in the soda lime container and float glass applications.

In some applications, bubbler systems are utilized to enhance convection flow patterns and to increase melter bottom temperature. Also, electric boost is installed to increase the production rate for a given melter size or to reduce emissions or a combination of these needs. Electric boost is also used to enhance glass quality.

End Port Furnaces

The above illustration shows a typical TECO end-port furnace, which is generally used by the container and tableware industries for the melting of soda lime glass. This type of furnace is also produced by TECO affiliates KTGSI and TECOGLAS.

In some applications, bubbler systems are utilized to enhance convection flow patterns and to increase melter bottom temperature. Also, electric boost is installed to increase the production rate for a given melter size, reduce emissions, or a combination of these needs. Electric boost is also used to enhance glass quality.

End-port furnaces are generally utilized in applications up to 600 tons per day to melt amber or green glasses. Side-port furnaces are used for greater than 300 TPD applications, which are typical for float glass and container industry applications.
