Heat Exchange in the Granulation Chamber of an Installation for Slag Dry Granulation

  • Published:
Metallurgist Aims and scope

In the blast-furnace production, fiery-liquid slags have temperatures of about 1400–1500 °C at the exit from the furnace. For the utilization of their sensible heat, the world leading countries develop special installations for slag dry granulation aimed at getting dry granulated slags and using the heat of liquid slags for the purposes of heating of air or another gas. In addition, the introduction of the process of slag dry granulation instead of the wet granulation of slag applied at present excludes the possibility of ejection of harmful sulfur compounds and does not require additional heat consumption spent for drying wet granulated slags. In the available methods aimed at the dry granulation of slags, it is proposed to use the air heated to a temperature of 500–600 °C in a boiler (utilizer) intended for the generation of steam, which is then either delivered to a turbine generating electric energy or directly used for the industrial purposes. We propose a method for the numerical analysis of heat exchange in the process of cooling of blast-furnace slag in the granulation chamber of the installation for dry granulation. By using this method, one can determine the optimal main size of the granulation chamber, i.e., its radius.
