Rotary Kiln Emissions Control

Every combustion-based kiln produces a flue gas, and what happens to that gas before it leaves the stack is as important as what happens inside the drum. Emissions control is a designed part of the kiln system, not an add-on, and it is what allows a kiln to operate inside the air-quality limits that govern industrial and waste processing.

The Treatment Train

Kiln flue gas is typically cleaned in stages: an afterburner holds gases at high temperature to destroy residual organics, scrubbers remove acid gases, and particulate filters such as baghouses capture fine dust. In a hazardous-waste kiln, this train is mandatory and extensive, removing contaminants before the cleaned gas is released.

Why Control Is Designed In

The choice of fuel, feedstock and kiln type shapes the emissions from the start, so the gas-treatment system is sized to match. An indirect-fired pyrolysis kiln produces a much smaller gas stream than a direct incinerator, for example, which changes the treatment entirely. Factoring emissions in at the design stage avoids the far greater cost of bolting on control equipment later to a plant that was never sized for it.
