摘要： A viewport for a combustion zone includes an inner casing having a flange extending into the combustion zone. A first layer of ceramic fiber insulation is exterior to the inner casing. A middle casing includes two panes of quartz glass separated by traverse plates. A second layer of ceramic fiber insulation is exterior to the middle casing. An outer casing is positioned to the exterior of the second layer of insulation. The middle casing includes L-shaped ledges having third and fourth layers of ceramic insulation. The panes of glass are each positioned between layers of insulation and the insulation positioned in the L-shaped ledges. The viewport is modular enabling the separation of the first layer of insulation, the middle casing, the second layer of insulation and the outer casing from the combustion zone for maintenance or repair. The viewport minimizes heat migration to the outer casing during use.

摘要： The state of a flame in a subject combustor of a gas turbine engine is acoustically monitored using a dynamic pressure sensor within the subject combustor and one or more additional sensors in nearby combustors. Dynamic pressure sensor output signals from the sensors are cross correlated to identify acoustic oscillations generated by a flame in the subject combustor and received by the sensors. The cross correlation may be constrained by a maximum time delay between correlated components of the signals, based on physical characteristics.

摘要： A method for monitoring a combustion process in the infrared wavelength range includes using a laser, which transmits a laser light beam along a measurement path in a certain wavelength range, which is selected in such a way that a gas therein to be detected in the combustion process has an absorption line, and that the emission wavelength of the laser detects the absorption line of the gas to be detected upon the tuning in the selected wavelength range. The concentration of the gas is determined as a function of the absorbed energy of the laser light beam. The intensity of the laser light beam is detected and is analyzed in order to determine the existence of a flame in the combustion process, and/or the quality of the flame.

摘要： A gas turbine combustor burns fuel from a fuel supply. The combustor includes a combustion chamber and a fuel delivery system for delivering the fuel to the combustion chamber. A pilot or fuel nozzle establishes a combustion flame in the combustion chamber by burning the fuel. One or more fuel lines operatively connect the fuel delivery system to the fuel supply. A flame spectrometer senses the level, such as the concentration level, of a fuel contaminant, such as sodium, within the combustion flame. A control system disables the fuel delivery system as a function of the contaminant's concentration level or accumulated concentration level.

摘要： In a pulse burner of the type wherein an air-fuel mixture in a combustion chamber is explosively burnt by an ignition plug and resulting flame is detected by a flame detector to control the operation of the pulse burner, there is used a flame detector which detects electric current flowing in the flame instead of a thermostat secured to a side wall of the combustion chamber.
