Combustion in incinerators occurs under controlled conditions within the stack. Incinerators are not affected by wind or other weather conditions, and they generally provide more efficient combustion, compared to open-air flaring.
Although some incinerators are actually enclosed flares, a true incinerator has controls to maintain a specific air-to-fuel ratio, a refractory lining and a minimum residence time, while an enclosed flare is merely protected from outside weather.
The most efficient combustion is provided by a true incinerator, typically being applied with waste gases and liquids, syngas or tail gas.
Horizontal forced draft
Controlled thermal oxidation of fluids (gas / liquid) in horizontal forced draft combustion chamber with adequate residence time to ensure the elimination of harmful components, with/without auxiliary equipment (energy recovery, DeNOx, etc.).
Vertical natural draft
Controlled thermal oxidation of gases in a vertical natural draft combustion chamber with energy input and control of combustion and cooling air to obtain superior thermal destruction.
Possibility of integrating chimney sampling to monitor emissions.
Suitable to ensure the elimination of harmful components, with a tight implantation and investment.
They use part of the heat of the combustion products to preheat the stream to be oxidized or to recover heat to another point in the process, through primary or secondary recovery.
In this way, the thermal efficiency of the process is increased, using less input energy.
