Myths & Facts

There is a lot of misinformation and misconception that needs to be rectified.

Waste Incineration

By the 1920s, waste incineration was a common method of waste disposal, simply used to reduce the volume of general solid waste. Notwithstanding their long history, the use of incinerators for Waste…

Get answers to your questions about our products and services.

Which technology is applied for burning the waste?

We produce counter-current rotary kiln based systems, for continuous operation, suitable for ANY waste, as long as the mixture makes it possible to achieve stable incineration process conditions. We don’t produce the (cheaper) batch wise processes. As from a practical point of view, batch orientated systems are not a reliable option to warrant emissions in compliance with the regulations. Also, operating costs for batch processes are much higher.

Is your incinerator a batch wise or continuous treatment process?

Our incinerators are designed for 24/7 continuous operation at variable rotational speed, with as main advantage that the process is stable, completely automated, tuned as such to minimize emissions and mainly without the need to supply external fuel during operation. Notwithstanding, our systems can operate intermittent as well, but the consequence is a significant higher fossil fuel consumption. We would definitely not recommend intermittent or a batch wise incineration process, considering the ongoing fluctuation on emissions and a much higher operating cost.

What sizes are your incinerator systems?

We produce incinerators with a thermal input capacity between 1.5MW and 20MW as a standard. The throughput always depends on the waste calorific value. Systems outside this range upon request.

Is there a limitation in waste calorific value?

In practice, there is no upper limit on calorific value. The throughput will be lower, because incinerators are sized on thermal input. On the low side, there are limits, because you can’t incinerate waste with say 100% water obviously. Waste types need to be evaluated case by case.

Which waste items are suitable for your incineration systems?

Our incinerators are designed for the most difficult wastes available; e.g. hazardous, chemical, toxic, (bio-)medical and infectious waste. The core of our process is always the same: counter-current rotary kiln, as this indeed makes it possible to accept and properly incinerate all these wastes (in contradiction with all “competing” technologies). We can adapt the feed systems for the waste with several options available, depending upon actual waste type, physical appearance and composition.

Is it necessary to pre-treat the incoming waste before it is fed to the incinerator?

Our incinerators are able to accommodate large variations in waste sizes, waste composition, calorific value (physical, chemical and thermal properties). They are engineered with a wide operational window on thermal input. With counter-current rotary kiln technology, usually there is no need for pre-treatment like grinding, chopping or mixing of the different waste streams.

Does your incinerator has a flue gas treatment system?

Our systems comply with the European Industrial Emissions Directive (2010/75/EU), which is the strictest on the planet. Flue gas scrubbers are implemented and inevitable to control the air pollutants. We have several options: dry, wet, dry + wet; depending on client requirements. A dry scrubbing system is the solution with the least impact on surroundings (no wastewater, no visible plume, no aerosols from the smokestack, emissions absolutely in compliance with all regulations anywhere in the world). Dry scrubbing is somewhat more expensive in construction and less compact, but the operating cost is much lower compared to wet scrubbing.

Is there a secondary combustion chamber in the design?

Our designs consist of a primary (rotary kiln) and secondary (post) combustion chamber and are in full compliance with the standards of the “European Waste Incineration Directive 2000/76/EC”. Our flue gas treatment systems reach levels far below the applicable EU emission standards, including minimum 2 seconds gas retention at >850°C in the post combustion chamber.

Are there built-in measuring points to check operating or emission parameters automatically?

Our incinerators are completely automated with DI ownership software, using PLC technology and top quality European automation components, for continuous measurement and file storage of different operating parameters. Our incinerators are installed with a CEMS for constant emission monitoring.

Does the system has an automatic emergency stop installed in case of a malfunction?

There is a full automated shutdown, in case of excessive operating conditions or loss of electrical power. It’s possible to resume operations when power supply is restored (short shutdown), without the need to empty the kiln and make a cold restart.

What are the typical uptime and downtime of the equipment?

There is a minimum annual uptime of 90%, but the typical uptime is 95%-98% (8,400 operational hours). The daily, weekly and monthly routine inspection and systematic maintenance tasks do not require downtime, neither does waste feeding or ash removal. The sole downtime is limited to only one single yearly shutdown for general plant overhaul, completed in less than 2 weeks.

How often does your incinerator system needs to be maintained/serviced?

Our systems operate 24 hours per day, 7 days per week, all year round. Daily, weekly and monthly routine inspection and systematic maintenance tasks are carried out by the operator during operations. The plant demands only 1 single pre-scheduled complete shutdown for annual general maintenance. This thorough maintenance service is executed by our maintenance team in 10-15 consecutive days. The plant requires low wear and tear repairs and minor replacement of parts.

How many people are needed to operate the plant?

Normally 2 to 3 people per shift, depending upon type of waste and size of the incinerator system. At least 2 people are needed out of safety perspective. One needs to be able to help the other in case of a dangerous situation, accident etc.

Is it possible to further utilize the heat generated by the incinerator during the operation?

Waste heat generated by the incinerator could be recovered and converted into combined heat and power (CHP); e.g. hot air, chilled air (for room cooling), hot water (for district heating), thermal oil, steam or electricity. For our smaller incinerator systems, we could make use of ORC technology to run the plant independently from the power grid.

How is the noise level?

We comply with the European noise emission regulation (Directive 2003/10/EC) or any other applicable legislation, regarding operator noise exposure. If noise is really critical, we can take specific measures to reduce this further; we have experience as such with really critical applications.

Are your incinerators suitable for salty environments (corrosion)?

Specific solutions are available for surface conservation in salty environments, upon client request and specific application.
