Waste Combustion Systems

Our society's trash and waste continues to increase in complexity and quantity. Plastics and other synthetic materials which resist natural decomposition create a greater threat to the environment and therefore place an increased liability on the waste generator. Burning of trash and waste is a logical approach to limit cost and liability, but the combustion process must be safe and controlled to meet today's stringent air quality regulations.

IWI offers a proven solution to cost effective waste disposal and renewable energy - the IWI Dual Reactor System. These units have been successfully used by health care facilities, industrial facilities, research facilities, institutions, municipalities and commercial operations throughout the world.

How the IWI Dual Reactor System Works

The IWI system utilizes a two-stage combustion process. In the first stage, waste is pyrolized into combustible gases. In the second stage, these gases are ignited and completely burned.

The two-stage process enables the Dual Reactor System to destroy a wide variety of materials in a non-polluting manner. Pyrolysis is the thermal decomposition of waste in an oxygen-starved atmosphere. Moisture and hydrocarbons are driven off leaving only a small amount of dry sterile ash.

As waste is fed into the primary chamber of the Dual Reactor System, it is exposed to very high temperatures. Burning of a small portion of the waste with a controlled quantity of air flowing up through the bed of trash produces the desired operating conditions. Unlike conventional incinerators, air velocities in the primary chamber are very low, thereby minimizing ash disturbance and particulate carryover. The pyrolysis gases are ducted to the secondary chamber.

The unique Dual Reactor System secondary chamber combines additional combustion air with the pyrolysis gases, creating a vortex action. As the gases begin to mix, positive ignition occurs resulting in complete combustion of all hydrocarbons. The combined effect of optimum turbulence, correct temperature, and adequate retention time insures maximum combustion efficiency.

For optimal performance an Air Pollution Control System is added to any of our systems. 

The process is fully automated and minimizes the requirement of an operator being in attendance to oversee the complete cycle once in progress.  Throughout the process the IWI HMI Control System ensures that consistent, thorough and the cleanest possible thermal treatment results are achieved.
