SICF 100 - 200
SMALL-SIZE INCINERATORS
Stationary Incinerator and flue gas cleaning/filter plant
CAPACITIES 100 – 200 kg/h

SICF Incinerator Units are combustion- and flue gas cleaning/filter plants with an excellent combustion capacity.

The main design demand for the construction of the incinerators are easy operability, rigid construction and long life time together with made in Germany quality and according to EC and local regulations.

FEATURES 

  • Installation of the unit is very easy and do not need big scale construction work, i.e. if you can prepare the RF concrete slabs beforehand, the parts of the unit can be unloaded from truck directly into place and can be fixed immediately,
  • Automatic ash discharging (moving bed systems): safe technology
  • Continuous incineration: the waste is moved over steps with a ram system (moving bed systems)
  • Incineration without grate: absolutely sterile ashes by a complete burnout in the combustion chamber.
  • Postcombustion chamber: elimination of odour and organic matters
  • Rigid construction: use of standard components
  • Refractory lining: resistant against wear, high heat storage, low heat emission of the furnace
  • Easy operability: automatic function control (moving bed systems)
  • 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).

Main combustion chamber

Fixed bed systems

The waste is incinerated in a two stage combustion chamber. The dimensioning of the combustion chamber and the controlled incineration ensure a minimum consumption of Diesel oil. The waste is burned directly on the refractory lining. Combustion air is blown into the incinerated waste by a nozzle system controlled by the incineration parameters. A mixing takes place between the waste and the air. Depending on the calorific value of the waste the temperature in the combustion chamber is approx. 850 °C. The temperature will be controlled by combustion air injection and burner operation.

Auxiliary fuel is only necessary at low calorific value and/or high moisture content of the waste. The combustion chamber is lined entirely with high quality refractory material. The refractory material of the step floor has high alumina oxide content and has high resistance against wear.

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

Moving bed systems

The waste is incinerated in a two stage combustion chamber. The dimensioning of the combustion chamber and the controlled incineration ensure a minimum consumption of Diesel oil.

Continuous incineration because the waste is moved over steps with a ram system. Incineration will be done without grate. Absolutely sterile ashes by a complete burnout in the combustion chamber. The waste is mechanically mixed and is burned directly on the refractory lining. 

The continuous incineration process is ensured by an automated system. Combustion air is blown into the incinerated waste by a nozzle system controlled by the incineration parameters. A mixing takes place between the waste and the air. Depending on the calorific value of the waste the temperature in the combustion chamber is approx. 850 °C. The temperature will be controlled by combustion air injection and burner operation. Auxiliary fuel is only necessary at low calorific value and/or high moisture content of the waste. The combustion chamber is lined entirely with high quality refractory material. The refractory material of the step floor has high alumina oxide content and has high resistance against wear.

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

Post-combustion chamber

The flue gas from the combustion chamber can contain not burnt components. In a post combustion chamber (secondary combustion chamber) an additional burner ensures the complete combustion of all smell and organic components. The selected residence time of the flue gas in the combustion chamber will be 2 seconds at 1.100 °C. A burner and a temperature measurement after the post combustion chamber ensure the destruction of organic pollutants and CO.

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)

FLUE GAS CLEANING SYSTEM

A gas treatment system in accordance with EC regulation will be installed in our incineration plants.

Each filter system will be adapted to the local requirements. Such systems are composed of an additive dosing system, 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 is stored in big bags and fed 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 ceramic filter elements.The filter will be cleaned periodically through pressurized air impulses.

Filter modules

CONTINUOUS GAS MONITORING SYSTEM
Option
Usable for automated moving bed combustion plant.

continuous gas monitoring system for incinerator units

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.
