Oxygen Potential in Basic Open-Hearth Furnaces

Advanced design methods for rotary hearth furnaces

*Tenova LOI Italimpianti, Italy, **Centro Sviluppo Materiali SpA, Italy ENVIRONMENTAL concerns and rising prices of fossil fuels have focused the steel industry’s attention on minimising emissions and improving heating efficiency in reheat furnaces. Additionally with the rise in competitiveness within the world steel market product quality can be a key strategic factor to gain a market, a facto...

Evaluation of the Cooling and Pavement Performance of Basic Oxygen Furnaces Slag Used in Asphalt Mixture

The basic oxygen furnace slag (BOF) was wide used in road construction, but there was a lack of characteristics in different asphalt mixtures. This study investigates the properties of hot-mixed asphalt (HMA) containing stone mastic asphalt (SMA), porous asphalt (PA) and dense-graded BOF as a partial substitution for natural aggregates. The purpose of this study is to evaluate various BOF slag ...

CFD Modeling Study of High Temperature and Low Oxygen Content Exhaust Gases Combustion Furnaces

This paper reports a CFD modeling study on the possibility of using high temperature and low oxygen content exhaust gases as oxidant for combustion in an industrial furnace by a written computer program. Under these conditions,the predicted results for the flow and heat transfer properties are compared with those under the several cases of conventional and highly preheated...

Fuels and Furnaces

The subject matter of this paper, if treated in the general sense, covers an extremely wide field to which it is impossible to do justice in the time allocated. It is even difficult to cover the subject adequately if we confine ourselves only to the furnace design of bagasse fired sugar mill boilers. I therefore intend to give a short summary of past and present bagasse furnace designs and cove...
