Furthermore, a great deal of additional energy is required for a thermal afterburning of the fumes.

All these combustible components are used as combustible gas in the afterburning according to the invention.

Stripping waste gas 8 is used in afterburning B of Claus waste gas 2.

During the post-combustion, the organic pollutants contained are oxidised up to produce carbon dioxide.

The physical configuration of this amplified signal means an end of the CO post-combustion in the converter vessel.

Low emissions values are due to a thermal integrated afterburning process.

The carbonization gas generated during the pyrolysis reduces natural gas consumption of the thermal post-combustion.

Thermal oxidisers destroy organic compounds thermally in a combustion chamber where a flame from the combustion of a fuel, normally natural gas, and the VOCs present in the waste gas, heat the waste gas stream.

At the same time, the transfer of the heat generated during afterburning to the almost slag-free metal bath is increased.

To this effect, the supply of primary oxygen is reduced, while the secondary oxygen-supply is increased for the benefit of the afterburning.

The energy required for this purpose is preferably obtained directly from the afterburning of the carbonizable residues.

The energy additionally obtained from the afterburning is almost completely transferred to the iron bath.

At the same time, the transfer of the heat generated during afterburning to the almost slag-free metal bath is increased.

Moving of the lance has proved advantageous for optimising the afterburning.

This will result in a very effective mixing and afterburning of the gases in each stage.

In an embodiment of the invention the burner of the post-combustion unit is operated with an additional combustion gas.

It is advantageous to provide for post-combustion of the process gas in the flow-through chamber.

In addition, the heating of the melting stage can be controlled independently of the post-combustion or of the scrap preheating.

To conserve energy during the thermal post-combustion the exhaust gases to be purified are fed through heat exchanger material.

The operating costs in thermal after?burning can be reduced in an autothermal after-burning mode if the concentration of carbon compounds in the waste gas is high enough.

This includes emissions from carbon containing additives (coke and coal dust, organic coatings of glass fibres and mineral wool) and flue gas cleaning (post-combustion).’;

This will assure that in the central zone, at which the bath surface is impinged with ore, the main afterburning of the CO will occur, which will produce the necessary energy for melting the ore, and that also carbon will be transported to this central zone which serves for the reduction of the ore.

That process gas is circulated and the residual sulfur compounds are burned. The heat required to desorb the laden adsorbent is made available by a heat exchange between the desorbing gas and the exhaust gas that has been heated by the heat of reaction resulting from the reaction of the residual hydrogen sulfide with oxygen in the incinerator (German Pat. No. 25 55 096).

For environ­mental and industrial policy reasons, the Commission of the European Communities decided to support the con­struction of a pilot plant of this type.

By contrast with earlier, conventional processes, a much higher afterburning of CO-gases generated during the decarburizing of the bath takes place right on the surface of the bath, whereby a larger portion of the energy liberated during afterburning is transferred to the bath itself since the foam-free slag layer hinders the heat transfer less than a foam layer would.

This is possible, without risks such as boiling over, due to the reduction of the slag to an absolute minimum according to the invention and leads to an essential increase in the efficiency of the afterburning of the generated carbon monoxide in the immediate vicinity of the metal bath.
