摘要： A radiant burner and method are disclosed. The radiant burner is for treating an effluent gas stream from a manufacturing process tool and comprises: a combustion chamber having a porous sleeve through which combustion materials pass for combustion proximate to a combustion surface of the porous sleeve; a combustion characteristic monitor operable to determine combustion performance of the radiant burner by monitoring infra-red radiation emitted from the combustion surface; and a radiant burner controller operable to control operation of the radiant burner in dependence upon combustion performance determined by the combustion characteristic monitor. Accordingly, aspects recognise that if a burner is suffering from an excessive flow of air the burner pad or combustion surface will typically cool, which results in an increase in unwanted emissions in the exhaust produced by a radiant burner. The cooling also results in a reduction in infrared radiation determined by the combustion surface. The hydrogen flame of the radiant burner and the hydrocarbon flame of the burner pilot typically do not emit infrared radiation and thus a change in infra-red an radiation, for example, intensity, quantity or frequency, emitted by the combustion surface of the radiant burner can be used to diagnose an “overflow” of cold gas, typically air, in the combustion mixture fed into the system, for example, the combustion chamber. Once diagnosed appropriate ameliorative steps may be taken and, for example, the burner control logic may be operable to compensate by reducing air flow into the burner.
摘要翻译： 公开了一种辐射燃烧器和方法。 辐射燃烧器用于处理来自制造工艺工具的流出气流，并包括：具有多孔套筒的燃烧室，燃烧材料通过该多孔套筒通过燃烧附近的燃烧表面; 燃烧特性监测器，其可操作以通过监测从燃烧表面发射的红外辐射来确定辐射燃烧器的燃烧性能; 以及辐射燃烧器控制器，其可操作以根据由燃烧特性监测器确定的燃烧性能来控制辐射燃烧器的操作。 因此，方面认识到，如果燃烧器遭受空气的过度流动，则燃烧器焊盘或燃烧表面将典型地冷却，这导致由辐射燃烧器产生的废气中的不期望的排放物的增加。 冷却也导致由燃烧表面确定的红外辐射的减少。 辐射燃烧器的氢火焰和燃烧器导向器的碳氢化合物火焰通常不会发射红外辐射，并且因此红外辐射的变化，例如由辐射燃烧器的燃烧表面发射的辐射，例如强度，数量或频率 可用于诊断进入系统的燃烧混合物（例如燃烧室）中的冷气体（通常为空气）的“溢出”。 一旦被诊断出可以采取适当的改善步骤，并且例如燃烧器控制逻辑可以通过减少进入燃烧器的气流来进行补偿。

摘要： A combustor nozzle includes a center body that defines an axial centerline. A shroud circumferentially surrounds at least a portion of the center body to define an annular passage between the center body and the shroud. A plenum is inside the center body and aligned substantially parallel to the axial centerline. A sensor extends inside the center body and is generally adjacent to the plenum, wherein the sensor detects a condition proximate to the combustor nozzle. A method for monitoring a combustor includes flowing a fuel through a center body axially aligned in a nozzle and flowing a working fluid through an annular passage substantially parallel to and radially outward of the center body. The method further includes sensing a condition inside the combustor using a sensor located inside the center body.

摘要： An optical waveguide with a tubular or hose-like housing is provided, which is used in a high-temperature environment, such as, for example, in a burner. The housing has an input opening, an output opening and a center line extending from the input opening to the output opening. In the interior of the housing, transparent spheres are lined up along with center line. The light is guided on account of the refraction of a light beam upon entering and exiting from the transparent spheres.

摘要： A combustion chamber (1), in particular in a gas turbine, has at least two burners (A-H) that are connected to a fuel supply (3) via controllable fuel valves (2′ and 2). Each burner (A to H) is assigned at least one optical measuring device (4) for detecting chemiluminescent radiation, and the combustion chamber (1) is assigned a pressure sensor (7) for detecting a combustion chamber pressure. The optical measuring device (4) and the pressure sensor (7) are connected to a computing and control device, which calculates a correlation value from the incoming measured values. A high correlation value signifies that the associated burner is prone to pulsation. The computing and control device (6) is designed in such a way that it determines the burner or a burner group with the highest correlation and controls the associated fuel valve(s) in such a way that more fuel is fed to the respective burner or the respective burner group, and the pulsation tendency thereof is thereby reduced.

The cooling apparatus provides cooling for an inspection probe such as a video borescope. The cooling apparatus includes an articulating guide tube having a control portion, an elongate flexible portion and an articulating section. The video borescope is inserted down through the articulating guide tube. A thermal protective sleeve surrounds and thermally insulates a portion of the articulating guide tube. Vortex coolers circulate cooled, compressed air within the cooling apparatus, thereby maintaining a cool video borescope operating temperature.
