Abstract

Numerous metallurgical oven chambers are economically heated with overhead radiation burners. Problems, however, arise through the unsatisfactory durability of their ceramic burner bricks. This project deals with the improvement of the durability and effectiveness of burner bricks and the increase of the heat reflection intensity of such ovens. Practical test results essentially confirmed the assumptions made following theoretical tests, (eg horizontal crack formation in porous materials when used for burner bricks, increased heat transmission intensity when surfaces were treated with high emission coatings). Burner bricks constructed of fire concrete with poor cement content show practically no damage despite reaching the theoretical limit of their tensile strength. On the strength of these test results practical recommendations could be made for the improvement of the durability and effectiveness of radiation burner bricks in overhead radiation heaters as well as for light burner bricks.
