gas conditioning tower of kiln

Permit with introductory note

Some hot gas from the kiln to the calciner is extracted. This gas passes through a mixing chamber and then into a conditioning tower, before de-dusting in a dedicated electrostatic precipitator. The bypass dust is collected for disposal while a portion of the cooled, de-dusted gas is returned to the mixing Get price
