2.2. INDUCTION FURNACES

The Cell has designed and demonstrated containment-cum-particulate removal system by using Scrubbing/ filtration technology. Following two pollution control systems have been devised for arresting fine particulate emissions:

• Impingement type scrubber for comparatively cleaner scrap.
• Bag house with cooling system for galvanized / imported scrap.

Salient Features of Technology  

• Workable swiveling hood which rotates about its axis to serve both the crucibles.
• Elliptical cut in the hood so as to enable charging of scrap & removal of slag.
• Minimum number of bends with proper radius.
• Fan (Heart of System) : Existing low pressure high volume replaced with high pressure fan capable of developing static pressure of about 14-16” WG.
• Emission levels

  • Before APCD …. 3000 mg/Nm3
  • After APCD ….< 150 mg/Nm3
• Efficiency of the system : 85 - 90%

Technology replicated in  25 units.
