Abstract
The invention relates to a method for producing a gaseous medium comprising steam, said steam being produced from a first fluid medium separated from the exhaust gas from combustion of a fuel in a steam generating step, said fuel being provided for burning for providing energy for heating said first fluid medium, comprising the steps of mixing the steam thus produced with exhaust gas from combustion of said fuel; and supplying at least one chemical substance different from air and water to said steam and exhaust gas mixture. The invention also relates to a device for producing a gaseous medium comprising steam.
Claims8
A method for varying the dew point of a mixture of steam and exhaust gas, the method comprising the steps of:
- (i) producing steam from a first fluid medium, energy for heating the first fluid medium being provided by burning a fuel;
- (ii) injecting a second fluid medium into the steam;
- and
- (iii) mixing the steam and the second fluid medium with an exhaust gas, the exhaust gas also being provided by burning the fuel,
- wherein the exhaust gas is not mixed with the steam before step (ii), and the dew point is varied by varying the amount of the second fluid medium that is injected during step (ii).
