Ferner ist ein Verfahren zur Verbrennung dea in Koksofengasen enthaltenen Aiimoniake im Rahmen der indirekten Ammoniakgewinnungsverfahren bekannt, wobei das an beliebiger tfteile anfallende, von Schwefelwasserstoff weitgehend freie Ammoniakwasser einem Desorptionaprozesa unterworfen wird und für den Desorptionsprozeas beliebige brennbare Gase mit Ausnahme von Unterfeuerungagasen, sowie auch Luft verwendet werden und die mit Ammoniak beladenen Gase oder die Luft als Verbrennungsmedien in den Winderhitzern von Hochöfen, den Hochöfen selbst, in Stahlwerks- oder Hüttenöfen oder als Komponenten zur Erzeugung von Gasen in Gasgeneratoren oder Gaaerzeugungsanlagen eingesetzt werden.Furthermore, a process for the combustion of the alimonia contained in coke oven gases is part of the indirect Ammonia production process is known, the amount of hydrogen sulphide occurring in any part being largely free ammonia water subjected to a desorption process and any combustible ones for the desorption process Gases with the exception of underfire gases, as well as air and the ammonia-laden gases or air as combustion media in the boiler of Blast furnaces, the blast furnaces themselves, in steelworks or smelting furnaces or as components for generating gases in gas generators or gas generation plants.
Bei der Verbrennung des in Koksofengasen enthaltenen Ammoniaks unter gleichzeitiger Verbrennung des Schwefelwasserstoffs zu Schwefel nach Patent 1 212 o52 hat sich gezeigt, nass es günstig sein kann, die Gesamtheit der Ent-Bäurerschwaden in weitgehend achwefelwasserstefffreie Ammoniakschwaden und weitgehend ammoniakfreie Schwefelwasserstoff Schwaden aufzutrennen, und sie getrennt für sich zu verbrennen, taxIn the combustion of the ammonia contained in coke oven gases with simultaneous combustion of the hydrogen sulfide to sulfur according to patent 1,212,052 has shown, wet it can be favorable, the entirety of the Ent-Bäurerschwaden in largely achulverstefffrei Separate ammonia vapor and largely ammonia-free hydrogen sulfide vapor, and separate them for themselves burn, tax
Ia Gegeneat« zu dem bekannten Verfahren müssen dabei zur Durchführung des Verfahrene zwar pindeatena zwei Verbrennungsöfen installiert werden· Ee ergibt sich jedoch der Vorteil» daas im <*uge d-.-r Aufarbeitung des .Schwefelwasserstoffs wieniger Kondensat abgezogen wemen muaa, daa Schwefel oder Schwefeldioxid enthalten kann.As a counterpart to the known process, two incinerators must be installed to carry out the process. However, there is the advantage that in the course of the processing of the hydrogen sulfide less condensate is withdrawn, as sulfur or May contain sulfur dioxide.

Sowohl den A.imoniak- wie auch den Schwefelwasserstoff-Desorptionssohwaden können zur Erleichterung dee Verbrennungsvorgan^es Zünd- oder Brenngase zugegeben werden.Both the ammonia and the hydrogen sulfide desorption boilers can be added with ignition or fuel gases to facilitate the combustion process.
Die Ammoniakverbrennungegase können nach ihrer Abkühlung im Abhitzekessel über den Kamin in die Atmosphäre entlassen werden.The ammonia combustion gases can be released into the atmosphere via the chimney after they have cooled down in the waste heat boiler.
Sie können aber auch nach Bedarf, nachdem Kondensate daraus abgezogen wurden, zur Einstellung von günstigen Temperaturen und Konzentrationen an Schwefelwasserstoff und Schwefeldioxid teilweise oder völlig den teilverbrannten Schwefelwasserstoffschwaden vor der Clausofen-Anlage zugegeben wordeneBut you can also as needed after having condensates out of it were withdrawn, in order to set favorable temperatures and concentrations of hydrogen sulfide and sulfur dioxide, partially or completely added to the partially burned hydrogen sulfide plumes upstream of the Clausofen plant
