Article Brief: Convective Heating for Ovens
75% Improvement in Energy Efficiency/Elimination of Distortion.

A comparison of the benefits of heating by convection and radiation at temperatures below 1000°C (1830°F) is presented in this article. The convective heating data is for a nonpolluting furnace that uses an electrically powered, ultra hot-air/ gas generator. The Airtorch source quickly and efficiently produces hot air or inert gas heated to temperatures as high as 1000°C (1830°F). The complete article is available in the October issue of ADVANCE MATERIALS & PROCESSES magazine (pages 213 to 215,10/1999). Read complete article and other similar articles
