Abstract
An integrated air-separating and water-heating apparatus intended for a boiler is presented.
Claims11
1-10. (canceled)
An integrated apparatus comprising
- an air compressor,
- a steam turbine coupled to the air compressor,
- a first heat exchanger,
- a means for feeding water to the first heat exchanger and from there to a boiler,
- a means for feeding compressed air from the compressor to the first heat exchanger,
- an air-separating device supplied with air compressed in the compressor,
- a heating means for heating the water downstream from the first exchanger,
- a second exchanger,
- a means for feeding water from the first exchanger to the heating means, from the heating means to the second exchanger, and from the second exchanger to the boiler,
- a means for feeding air from the air compressor directly to the second exchanger upstream from the first exchanger, without passing the air through a preheating means, and
- a means for feeding the air from the second exchanger to the first exchanger.
8 more elements
A method of heating water intended for a boiler, comprising;
- heating water in a first heat exchanger by an exchange of heat with air from a compressor driven by a steam turbine,
- feeding the air cooled in this first exchanger to an air-separating device,
- wherein the water from the first exchanger is reheated and fed to a second exchanger, where it exchanges heat with air from the compressor, the air from the compressor not being preheated between the compressor and the second exchanger, the air cooled in the second exchanger is fed to the first exchanger, and the water heated in the second exchanger is fed to the boiler.
