Dilution option
FIB has developed a proprietary technology to allow an even greater heating by means of convection. The technology consists of having additional air flow around the burners. This air will avoid the heating curve to be too aggressive on the surface of some pieces and will tend to decrease the speed of heating up to avoid thermal issues on the charge. This option is recommended for heating up refractory material, subject to initially a lot of water content which has to escape from the material to avoid cracks.
