Recuperative Furnace

Capability Summary

TECO pioneered the use of recuperators. The use of special steels and refinements to the design allows the recuperators to be successfully used on furnaces to melt a variety of glasses, allowing higher melting rates and more efficient energy consumption than direct fired air-fuel furnaces.

Recuperative furnaces are generally used by the container industry for the melting of soda lime glass and the textile fiber industries for the melting of low-alkali borosilicate glasses. This type of furnace is also produced by TECO affiliates KTGSI and TECOGLAS.

TECO recuperative furnaces are characterized by their low-fuel consumption and low emissions, while producing high-quality glass and achieving a long campaign life.

In some applications, bubbler systems are utilized to enhance convection flow patterns and to improve melter bottom temperature. Also, in some applications, 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.

Recuperative-type furnaces are used for glass-melting applications up to 250 tons per day.

Fiberglass Projects

Country: China - Duration: 2014 - 2016

An e-glass type fiberglass plant, shown here, was commissioned in China for the purpose of producing 7-10 micron fiberglass. The capacity of the furnace was 65 metric tons per day (72 U.S. tons per day).

TECO designed the batch plant, recuperative furnace, channel and forehearths. TECO also provided criteria engineering information for the plant design/construction and for building and process utilities.

The batch plant included pneumatic materials handling and mixing, and was designed for the same capacity as the furnace. However, materials handling and control system interfaces were provided to easily accomodate the addition of the second furnace at a later date.

The heat-up and commissioning of the project went smoothly and the fiberglass production started within three hours after pulling glass at the bushings.
