For the operation of a boiler, natural gas and air are burned. The natural gas fed consists in a mixture of 90% methane and ethane. In addition, to ensure complete combustion, it is fed air with an excess of 10%. From the combustion process, a gas stream of combustion at 820 C made up of carbon dioxide and water, this is fed to an exchanger of heat that increases the temperature of the air that will be fed to the boiler to 390 C. steam obtained from the boiler, which is at 250 C and 1 MPa, enters a heat exchanger to heating a juice, with a Cp of 4.150 kJ/(kgK), from 25 C to 85 C, resulting in a current at 70 C with 20% liquid.
