Window device, diagnosis system for combustion processes, and combustion chamber

Abstract

A window device for a space laden with carbon-containing particles, in particular, for a combustion space, comprising at least one optically transparent window element, is proposed, the at least one window element having a coating comprising an oxidation catalyst material for degradation of carbon-containing window contaminations.

Description

[0001] This application is a continuation of international application number PCT / EP2006 / 001524 filed on Feb. 21, 2006. [0002] The present disclosure relates to the subject matter disclosed in international application number PCT / EP2006 / 001524 of Feb. 21, 2006 and German application number 10 2005 009 285.3 of Feb. 22, 2005 which are incorporated herein by reference in their entirety and for all purposes.BACKGROUND OF THE INVENTION [0003] The invention relates to a window device for a space laden with carbon-containing particles, in particular, for a combustion space, comprising at least one optically transparent window element. [0004] It may prove necessary to observe combustion processes. Window devices of the kind described at the outset are required for this. SUMMARY OF THE INVENTION [0005] In accordance with the present invention, a window device is provided, which can be employed in a simple way. [0006] In accordance with an embodiment of the invention, the at least one window...

AI Technical Summary

Benefits of technology

[0005] In accordance with the present invention, a window device is provided, which can be employed in a simple way.

[0008] In accordance with the invention, a coating consisting of an oxidation catalyst material for carbon is provided. Carbon can thereby be catalytically oxidized to volatile constituents, in particular, during the combustion of hydrocarbons, so that window contaminations can be chemically degraded. A self-cleaning effect for the corresponding window device is thereby provided, whereby the observability is, in turn, ensured.

[0017] The coating can be produced in a simple way by vapor-depositing. A thickness of the coating in the nanometer range or submicrometer range can thereby be produced, which has a sufficient oxidation catalyst property and, on the other hand, does not impair the transparency of the window element to any considerable degree.

[0018] It may be advantageous for the coating to be subjected to a temperature treatment. This may possibly ensure better adhesion of the corresponding coating; for example, the coating is sintered.

[0020] It is then expedient for the coating to face towards the inside area of the space laden with carbon-containing particles so as to be able to degrade window contaminations coming from the inside area.

Problems solved by technology

The transparency is thereby impaired, and, in the worst case, observation of the space is no longer possible, i.e., the window device no longer fulfills its function.
