Benefits of technology

"The present invention is about a once-through steam generator (OTSG) that uses a combustion system to generate flue gas, which is then converted into steam through a steam generation process. The flue gas is then returned to the combustion system for recirculation. The invention provides a more efficient and cost-effective way to generate energy through a steam generation process."

Problems solved by technology

These prior art systems and apparatus, however, are not the most efficient or effective.
Additionally, these systems have a significant amount of solids deposition on the inner surfaced of the steam generator tubes.
Additionally, the cost to erect these apparatus is typically very expensive.

Embodiment Construction

[0015]The following detailed description shows the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made for the purpose of illustrating the general principles of the invention and the best mode for practicing the invention, since the scope of the invention is best defined by the appended claims. The invention is capable of other embodiments and of being practiced or carried out in a variety of ways. It is to be understood that the phraseology and terminology employed herein are for the purpose of description and not of limitation.

[0016]Referring now to FIG. 1, shown is a schematic illustration of one embodiment of the present invention. Numeral 10 broadly denotes the overall process. Combustion air 12 enters the process through an air input / output apparatus 13 and is then fed into a combustion system 20 to generate flue gas 28. The flue gas 28 is then fed into a steam generation system 40 to generate ste...

Abstract

A once-through steam generator (OTSG) creating steam from feedwater by heat provided by flue gas. Combustion air is introduced into the OTSG through an air input / output apparatus. It is then fed into a combustion system to generate the flue gas. The flue gas is then fed into a steam generation apparatus to generate steam. The flue gas is returned to the air input / output apparatus to mix with and preheat the combustion air. Steam is created by the passing of the flue gas across a series of tube contained within the OTSG. The tubes are arranged in a combination counter-current / co-current configuration to provides for the minimization of the creation of solid deposits in the tubes.

Description

REFERENCE TO PENDING APPLICATIONS[0001]This application does not claim the benefit of any pending patent application.REFERENCE TO MICROFICHE APPENDIX[0002]This application is not referenced in any microfiche appendix.BACKGROUND OF THE INVENTION[0003]The present invention is generally directed toward an apparatus to create steam. More specifically, the present invention is directed toward a once through steam generator.[0004]The prior art has many different types of steam generating systems and apparatus. These prior art systems and apparatus, however, are not the most efficient or effective. Additionally, these systems have a significant amount of solids deposition on the inner surfaced of the steam generator tubes. Additionally, the cost to erect these apparatus is typically very expensive. Accordingly, there is a need for an improved steam generator.SUMMARY OF THE INVENTION[0005]The present invention is generally directed toward a once-through steam generator (OTSG).[0006]One aspe...
