FEATURES 

  • Installation of a plant is easy
  • Automatic ash discharging: safe technology
  • Continuous incineration
  • Post combustion section: elimination of odour and organic matters
  • Lining: resistant against wear, high heat storage, low heat emission of the furnace
  • Easy operability: automatic function control
  • Low maintenance: all important components are clearly arranged and easy to access
  • Made in Germany quality: long-life cycle


ENVIRONMENTAL FRIENDLY

Two stage incineration for low emission values
The incinerator is equipped with an EC standard filter system (see flue gas cleaning system).

COMBUSTION CHAMBERS

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

Oven of a combustion plant
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 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)

STEAM BOILER
Optionally 

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 or as a separate system.

Depending on the local requirement and on the final engineering needs.

Therefore every boiler is tailor made product.

Upon request, we design a tailor made solution for you!

FLUE GAS CLEANING SYSTEM

A gas treatment system by means of a standard dry sorption system in accordance with EC regulation will be installed in our incineration plants.

The design of the flue gas cleaning system can vary according to the waste characteristic and the waste volume.

Each filter system will be adapted to the local requirements. Such systems can be composed of an additive dosing system, a bag filter system or a ceramic filter system and a draft fan.

The additive can be varied according to waste characteristics. Mostly sodium bicarbonate is indicated, with addition of activated carbon. This additive can be stored in big bags and can be feed by an air conveyor system. The sodium bicarbonate is an efficient reagent to remove SO2, HCl and HF. The activated carbon removes heavy metals and dioxin.

The products from the neutralization reaction are removed by a filter with bag filter or ceramic filter elements. The filter will be cleaned periodically through pressurized air impulses.

Filter unit with bag filters for a stationary combustion plant
Of course, each system has its own limits. These are the maximum weight percent of the fuel for Chlorine <0.6 % wt, Sulphur: <0.3 % wt and Nitrogen: <0.9 % wt in order to comply with the European emission limit values by using the dry sorption system. (wt means weight percent). Therefore our plants are equipped with a bypass system for the connection of an additional flue gas scrubber. This ensures easy retrofitting. The advantage is obvious. We will protect you from unnecessary expenses if, for example, the waste composition is not clarified or its use changes.

CONTINUOUS GAS MONITORING SYSTEM
Optionally  

Usable for automated combustion plant.

Envisaged analyses could be HCL, CL2, NOX, SOX, CO and TOC. The operation frequency can be either continuous operation or activation at a predefined frequency or upon demand.
