Demonstration of heat recovery system in rerolling mills
AIR POLLUTION CONTROL :
  • A technology for controlling air pollution from pulverized coal fired re-rolling millsĀ have been developed with emphasizes on usage of low ash coal having ash content less than 10 % and implementation of better feeding, firing and operating practices.
SALIENT FEATURES OF COUNCIL'S TECHNOLOGY :
  • A high efficiency cyclone based on computer aided design having in volute entry at the top in place of tangential entry was provided so as to reduce the pressure drop.
  • An impingement type stainless steel scrubber was provided after cyclone so as entrap the remaining superfine fine dust emissions from the flue gas and to bring down the emission levels below prescribed standards.
  • Use of aerodynamically well designed and balanced ID fan
  • Auxiliary items like rotary valve, gate valves, pressure taps, etc. for efficient working of APCD.
  • Efficiency of the pollution control system is more than 90 %.
