Abstract
A combustion system including a unit for producing oxidizing gas, a combustion apparatus, a unit for condensing the combustion fumes by bringing the combustion fumes into contact with at least one coolant liquid, a recycler, and a unit for providing molecular oxygen. The unit for producing oxidizing gas makes it possible to supply the combustion apparatus with an oxidizing gas originating from the mixing of molecular oxygen and the recycled portion of the dehumidified gas. The combustion system also includes a regulating unit having the function of automatically regulating the temperature of the coolant liquid of the condensing unit and/or a heater for heating the recycled portion of the dehumidified gas.
Claims30
A combustion system comprising:
- a unit for producing oxidizing gas,
- a combustion apparatus allowing for combustion of a fuel by using said oxidizing gas,
- a condensing unit suitable for condensing the combustion fumes produced by the combustion apparatus, by bringing the combustion fumes into contact with at least one coolant liquid, so as to produce a dehumidified gas,
- a recycler for supplying the oxidizing gas production unit with at least one recycled portion of the dehumidified gas at an outlet of the condensing unit,
- a unit for providing molecular oxygen and for supplying molecular oxygen to the oxidizing gas production unit, the oxidizing gas production unit supplying the combustion apparatus with an oxidizing gas originating from mixing of molecular oxygen and the recycled portion of said dehumidified gas,
- a regulating unit, which has a function of automatically regulating a temperature of the coolant liquid of the condensing unit,
- and at least one of the following technical features and/or:
- (a) at least one sensor for measuring an absolute or relative humidity in the recycled portion of the dehumidified gas and/or at least one sensor for measuring an absolute or relative humidity in the oxidizing gas and/or at least one sensor for measuring an absolute or relative humidity in the combustion fumes, and the regulating unit has a function of automatically regulating the temperature of the coolant liquid of the condensing unit-based at least on the absolute or relative humidity measured in the recycled portion of the dehumidified gas and/or based at least on the absolute or relative humidity measured in the oxidizing gas and/or based at least on the absolute or relative humidity measured in the combustion fumes;
- and/or
- (b) an operating range defining a maximum absolute or relative humidity and a minimum absolute or relative humidity, and the regulating unit has a function of automatically regulating the temperature of the coolant liquid of the condensing unit so as to keep the absolute or relative humidity of the oxidizing gas within said operating range of the combustion apparatus.
