TOTAL WASTE TREATMENT

The FRI range allows daily working time up to 24 hours. FRI equipment is made in two steps, including a primary combustion chamber, with a hot-hearth construction, which ensures the total destruction of the waste. An integrated post-combustion system completes the process, to guarantee maximum gas turbulence, and ignite the gases which remained unburnt during the first combustion. These gases are maintained for a minimum of 2 seconds at temperatures from 900°C to 1200°C, thus ensuring complete incineration of its components (oxidation).

SOLID WASTE LOADING

The FRI series incinerators are designed for automatic loading with hydraulic assistance. Loads of all types of waste are done through a front access, which reduces heat loss during loading.




AUTOMATIC DE-ASHING

The discharge located under the incinerator is separated from the combustion chamber by means of a hydraulically controlled ashes removal hatch.

AUTOMATIC DE-ASHING

The discharge located under the incinerator is separated from the combustion chamber by means of a hydraulically controlled ashes removal hatch.

The ashes extraction operation is programmable and can be carried out before the start of a new cycle, or at the end of the cycle.

The ashes removal cycle from the combustion chamber has a selector to allow the ashes to be poured by gravity into bins arranged for this purpose.

FILTRATION OF EMISSIONS (FUMES)

There are different possibilities. From the incineration process, by pyrolysis or oxidation, the waste is transformed into fumes which must be treated. INFIGROUP offers all kinds of different filtration methods, up to the adapted dry treatment (ceramic ) which complies with CE standards. For sizes of 500kg/h and over, only ceramic filtering is to be considered.

Ceramic filtration is a combination of cyclone filter and ceramic filter. It is the only one certified 100% CE. Its role is to regulate the flow of releases from gases in the event that the installation does not function properly (non-optimized regulation of burners, anomaly in oxygen management, etc.). The dust, already oxidized in the post-combustion, is sent to a cyclone in order to recover the remaining dust. The gases are meanwhile cooled to be able to be treated. The microparticles are captured by the reagents (dehydrated lime + activated carbon) injected into the dilution reactor and led to the ceramic filter.

Example of the recovery of the heat from combustion, into electricity

Pack Energie Électricité

The heat ofcombustion is used to feed an ORC (OrganicRankine Cycle) or a steam turbine, for self-consumption or resale to the national grid

Energy Pack Heat

The heat of combustion is used to produce hot water or steam, for sanitary or industrial applications .

Energy Pack Cold

The heat of combustion is used to operate a cold by absorption system, for air conditioning or industrial refrigeration applications.

 

WASTE GRINDERS OR SHREDDERS

For large solid waste, we have a whole range of Grinders and Shredders, which allows to put the waste at an acceptable size into the incinerator.

A SAFE AND PROVEN SOLUTION FOR THE TREATMENT OF SPECIAL SOLID, LIQUID OR SOGGY WASTE

- Capacity range from 500 kg/h up to 3 t/h, per incineration line;

- Waste heat recovery with LVH from 2 000 kJ/kg up to 12 000 kJ/kg

With a very different design from traditional incineration systems, special waste processing systems consist of a rotary tubular furnace, a post-combustion chamber, a boiler (heat exchanger) for steam generation (possibly combined with a waste heat recovery device), and a specific smoke treatment (filtration).

The general principle consists in the combustion of waste at high temperature, between 900°C and 1 200°C, in the rotary kiln or in the post-combustion chamber which completes it. The introduction of waste into the furnace is done depending on the nature of the waste:

  • Solid waste is introduced by a feed pusher in the tubular body by the rotary movement of the furnace
  • Liquid and gaseous waste can be introduced at two levels, either into the tubular body of the furnace, or directly into the post-combustion chamber via burners or specific injection nozzles. This proven process ensures complete destruction of hazardous waste, thereby reducing the emissions and helping to protect the environment.
