We working on solutions!


The incineration without grate enables a complete and sterile incineration of critical waste. The rigid construction and the easy operability improve the mobile usage in site camps.

Our Incinerators has an excellent combustion capacity.

Our SIBF are stationary plants.

Our transportable incinerator unit (TIU) can be put anywhere into operation.

Latest burner and control technology, and of course a full flue gas cleaning is the basis that the plant meets the highest environmental standards. 


The furnace consists of a main combustion section and a post combustion section in the combustion chamber.

Through a chute, the waste reaches the heart of the furnace, the combustion grate.

Depending on the application, a suitable system is selected from a wide range of variants, such as roller grate, feed grate or reciprocating grate. The design of the combustion grate as well as the movement of the individual grate bars or grate rollers intensively mixes the waste introduced. An even and sufficient air supply from below, with the air required for combustion (primary air), produces an excellent burnout. The slag is removed by a discharge system suitable for the application.

Main combustion section
Temperature: 850 °C
Residence time of waste: 30–60 minutes

The incineration process produces a sterile ash quality. 

The flue gas from the main combustion section can contain not burnt components. Therefor the combustion chamber above the grate forms the reaction chamber for further combustion of the resulting gases. To ensure that combustion is as complete as possible, further combustion air (secondary air) and, if necessary, recirculated flue gas are injected in a targeted manner. That ensures the complete combustion of all smell and organic components. The selected residence time of the flue gas will be 2 seconds at up to 1.100 °C.

Post combustion section

Temperature: 1.100 °C
Residence time of flue gas: > 2 seconds

The incinerator is equipped with an EC standard filter system (flue gas cleaning system)


Automated feeding and automated slag extraction. The feeding will be done automatically via a dosage bin to the solid waste feeding system, consisting of a conveyor system and a double flap gate system. Absolutely sterile ashes by a complete burnout in the combustion chamber, because the waste is mechanically mixed!


The hot flue gas is cooled down from a temperature of approx. 1100 °C to 600 °C in a cooler system. To ensure a good cooling effect, at its downstream installed air cooled heat exchanger will cool the flue gas down to a temperature of between 200 °C up to 250 °C (averagely 230 °C). The cooler system is mounted between the incinerator and the filter plant. The advantage is that this facility do not require water consumption.


The hot flue gas from the combustion plant is cooled down in a boiler casing to about 400 °C. We install the boiler walls within the combustion chamber. Please note that a boiler depends always on the requirements of the customers. Therefore every boiler is tailor made product. It is not a standard part! Upon request, we design a tailor made solution for you! In case of installation of a steam boiler the above mentioned cooling systems are not applicable.


A lance system is consisting of one or more sprayers in the combustion chamber and a pumping unit for it. It will spray the waste in liquid form into the combustion chamber, but not more than 10% in weight per feeding sequence. Because, liquid spraying into combustion chamber can cause a rapid cooling down of the temperature in the chamber and endanger the incineration process in one hand, the liquid waste needs additional evaporation energy and this reduce the incineration capacity of the unit on the other hand. Burning of high-calorific-value-materials is itself a problem of overheating, not the substance. Therefore, the total amount of waste must be compensated in case of high calorific value. The incineration of liquids is also possible with special burner systems.


Dry flue gas cleaning system according to EC standards.
The flue gas system mainly consists of:

  • Dry sorption system (standard)
  • Fan and stack.


Sodium bicarbonate mixed with activated carbon is a very effective additive for SO2, HCI and HF, heavy metals, dioxins, etc. The quantity of Sodium bicarbonate and activated carbon depends on the unit size and the requirements. 

The residuals and fly ash are removed in a fabric filter. The particle removal creates a filter cake, which supports the removal efficiency. Depending on the measured differential pressure across the filter, the parts of the filter elements are cleaned by means of pressurized air impulses.


A fan transports the waste gas to the stack.

(Continuous Exhaust Gas Monitoring)

Envisaged analyses could be:

  • Chlorides (HCl, Cl2),
  • NOx,
  • SO2 as SOx,
  • Carbons as TOC,
  • CO,
  • TSP (total suspended particles),
  • etc.

All units are special designs.

The values given can vary accordingly in the projects.
