The purpose of an incinerator is to deplete the harmful components from a process waste stream by oxidation as it cannot be emitted to the atmosphere or used as ordinary fuels. Often, the waste stream is Carbon Monoxide and in that case, the Incinerator is called CO-combustor.
An Incinerator consists of a refractory lined vessel with one or several special conventional burners with injectors for the to incinerate gasses. The vessel creates the required residence time whereas the burner(s) create(s) the high-temperature environment. Further, the waste gas needs to be mixed with a certain flowrate of the oxidation gas, air.
The latter process is the crucial aspect of the incinerator and is determining for its performance.
At the effluent of the incinerator a HRSG is located which produces steam.
