Combustion system capable of operating with a recycling of combustion fumes

A combustion system comprising:

• a combustion device for combusting a fuel by using at least one oxidizing gas and which comprises an outlet through which combustion fumes can be discharged;
• a supply unit for supplying oxidizing gas and which is connected to the combustion device for supplying the combustion device with oxidizing gas, said oxidizing gas supply unit comprising a mixer and a gaseous dioxygen source which supplies a dioxygen-rich gas and which is connected to a first inlet of the mixer;
• a main discharge circuit connected to the outlet of the combustion device and opening to open air;
• a recycler which comprise a recycling loop between the main discharge circuit and a second inlet of the mixer, at least one recycling fan or compressor mounted on the recycling loop and adapted to circulate a gaseous fluid in the recycling loop, towards the second inlet of the mixer, from a connection of the recycling loop with the main discharge circuit;
• a bypass which is connected to the recycling loop downstream of the recycling fan or compressor and which opens to the open air so as to at least be able to supply the mixer with air entering the bypass;
• and
• a control unit adapted to control at least the recycling fan or compressor.
