STACK AND FILTERING SYSTEMS

• CYLONES
  • They are dry type dust and soot collectors.
  • They operate under the principle of centrifugal forces.
  • They are the most simplest and practical equipment in flue filtering systems.
  • The dust and shoot are obtained from the cyclone by airlock.
  • These systems are effective for ø20µ and larger particulates.
  • The cyclones are provided environment ministry value of emissions as designed according to the capacity requirements.

• MULTY-CYCLONES
  • They are dry type dust and soot collectors.
  • They operate under the principle of centrifugal forces.
  • The micro-cyclones are developed to make benefit of high capacity operation, which increases the efficiency.
  • These systems are effective for ø10µ and larger particulates.
  • The cyclones are provided environment ministry value of emissions as designed according to the capacity requirements.

• WET SCRUBBER FILTERS
  • Flue gases are wet to move in the water curtain or under the water spraying by nozzles.
  • Dust and soot in wet flue gasses have heavier and then leave from flue gasses by crashed to a surface or centrifugal forces.
  • White smoke is exit from stack by means of water is vaporized by heating of flue gasses.
  • These systems are effective for any size of particulates.
  • Some harmful gasses can be kept in flue gasses by means of add some chemical material to the filter water.
  • However, since flue gas and filter water mixture acidic medium, the collected wet soot and dust are not neutralized before disposal.
  • Since acid is formed from the contact of smoke with water, wet filters and the following chimneys must be made of acid-resistant stainless steel.
