Continuous Feed Incineration Systems




The ECO CF Model is custom sized and can process larger volumes of waste starting at 250 kg per hour and up to 100 tonnes per day.  All CF Models are controlled and monitored by Eco Waste Solutions' proprietary 4G System Controls.

The process for a continuous feed incinerator differs from the batch incinerator.  The waste is charged into the continuous-feed Primary Chamber after it has achieved operating temperature of 600°C to 850°C.  The loading method and configuration may vary but as the name implies waste must be supplied to the incinerator on a continuous basis.  Typically the waste is delivered to the system using a mechanical materials handling device such as a skid steer loader or conveyor and a waste charge or load is deposited in the first stage of the system via a hopper.  The hopper directs waste towards the Primary Chamber where it is moved by a mechanical ram or platen that will push the waste into the system.  The Operator is isolated from the heat of the process by a guillotine style door.  Although this process may be highly automated, generally the Operator is required to be available to load the ram hopper every 20 minutes or so during the burn cycle.

Within the Primary Chamber the waste bed moves slowly along the stepped floor grate as it is pushed by a series of transfer rams.  This phase, which takes up to 6 hours, the solid waste is transformed into a gas that is drawn into the Secondary Chamber.  What remains in the continuous-feed Primary Chamber is sterile non-combustible material such as metals and glass and a non-toxic, non-leaching ash that is safe for disposal on-site.

 

In the Secondary Chamber the combustion gases are exposed to a highly-oxygenated and extremely turbulent environment for a minimum of a 2 second retention time at a temperature of 1000°C to complete the combustion reaction.

 

Given the increased turbulence of the continuous-feed Primary Chamber compared to that of a batch incinerator the off-gases may require an Air Pollution Control (APC) system.  The emission levels mandated by local environmental regulations and the waste composition will dictate the design selection of the APC.  Typically the APC design includes stages to cool, neutralize and capture entrained particulate matter within the exhaust gas stream, before they can exit the stack. 

 

The ash produced by a continuous-feeding incinerator requires continuous-ash-discharge.  Most commonly this function is performed by a wet ash conveyor system that will operate automatically.

The Continuous Feed Incinerator Systems (CF Models) are also available in a containerized mobile format - the ECO Mobile CF Model.
