Abstract:
Vorrichtung zur Bestimmung einer Partikelumwandlungsintensität in einem Vergaser. Die Aufgabe besteht darin, die Vorrichtung so zu gestalten, dass sie eine laufende Bestimmung der Partikelumwandlungsintensität in einem Vergaser oder sonstigen Prozess für eine Partikelvergasung ermöglicht und als Regelgröße für eine Energiezufuhrregelung heranziehbar ist. Die Aufgabe wird durch eine Vorrichtung, umfassend eine Kamera (7) zur Aufnahme eines sichtbaren Wellenlängenbereichs in einem Aufnahmebereich (8), der einen Vergasungsvolumenstrom (6) des Vergasers kreuzt, eine gekühlte Referenzfläche im Aufnahmebereich, wobei der Vergasungsvolumenstrom zwischen Kamera und Referenzfläche (9) verläuft und die Schnittfläche von Aufnahmebereich und Referenzfläche einen Messbereich bildet sowie eine Auswerteinheit zur Erfassung mindestens eines Intensitätswertes im Messbereich, gelöst.
Abstract:
A monitoring method makes use of a furnace monitoring system. The monitoring method photographs the inside of the furnace, compares and analyzes thermal wavelengths and images in the furnace with values set on the temperature monitoring program installed to a computer, emits a warning sound when a temperature beyond a set range is detected, performs operation so as to automatically increase or decrease the temperature in the furnace, outputs the temperature data of monitoring regions such that a user can easily view the temperature data, and stores the temperature data in the computer. Thereby, it is possible to monitor a burner from the time of initial ignition to the time of extinguishment in order to preemptively prevent an accidental explosion resulting from faulty ignition.
Abstract:
The present invention provides a method and apparatus for detecting fire in a monitored area. In a preferred embodiment, this method is seen to comprise the steps of: (1) capturing video images of the monitored area in the form of two-dimensional bitmaps whose spatial resolution is determined by the number of pixels comprising the bitmaps, (2) cyclically accumulating a sequential set of these captured bitmaps for analysis of the temporal variations being experienced in the pixel brightness values, (3) examining these sets of bitmaps to identify flusters of contiguous pixels having either a specified static component or a specified dynamic component of their temporally varying brightness values, (4) comparing the patterns of the shapes of these identified, static and dynamic clusters to identify those exhibiting patterns which are similar to those exhibited by the comparable bright static core and the dynamic crown regions of flickering open flames, and (5) signalling the detection of a fire in the monitored area when the degree of match between these identified, static and dynamic clusters and the comparable regions of flickering open flames exceeds a prescribed matching threshold value.
Abstract:
An ash melting furnace capable of a high-efficiency, stable operation and accommodating load variations, which is used for mixed melting for heating and melting main ash and flying ash as burned ash simultaneously, characterized in that main ash (coarse grain ash) in an upper layer and flying ash (fine grain ash) in a lower layer are supplied in layers from one end of the furnace body and heated and melted by a burner while being moved to the other end, whereby enabling the burner, when an oxygen enriched burner is used, to properly control an oxygen amount added to air (concentration change included) and, in response to a heated and melted ash condition caused by the combustion of the oxygen enriched burner, to properly control, in addition to fuel supply amount, an ash supply amount as required by a change in the oxygen enriching concentration.
Abstract:
In order to enable particularly prompt detection of temperature distribution and concentration distribution of reaction products occurring during the combustion process as well as flame parameters (F), the invention provides for an image (B1, B3, B4, B5, B6) of a flame to be picked up, whereby a physical distribution of a combustion-process characteristic parameter for at least one predefined spectral range (203, 204, 205, 206) is determined on the basis of local resolution intensity of said image (B1, B3, B4, B5, B6).
Abstract:
An image processing method for flame monitoring based on the formation of a video signal characteristic to the combustion process. In accordance with the method, the flame is monitored by each fire-box camera essentially from its side, whereby the video signal is adapted to cover at least an entire ignition area of a single burner, the video signal is continually processed to define the average intensity level corresponding to the steepest intensity gradients, and for each averaged level, the corresponding spatial or time coordinates of the continuous video signal, which define the location of the ignition area, are determined. The method in accordance with the invention extracts from the ignition and combustion process abundant information helpful in the control of combustion.
Abstract:
A system for a gas turbine engine includes an igniter event conductor. The igniter event conductor has a first portion adjacent an igniter of the engine and in a combustion chamber of the engine and a second portion apart from the igniter and apart from the combustion chamber. The conductor is adapted to conduct an aspect of an igniter event at the igniter from the first portion to the second portion. A sensor is coupled to the second portion of the conductor to sense the aspect of the igniter event.

A burner includes an electrically powered heater configured to output heat energy to a burner portion configured to contact a fuel stream or a combustion reaction supported by the fuel stream.
Abstract:
Method of controlling the operation of a combustion device (1) to provide safe and reliable operation while reducing NOx emission that includes providing a flow of fuel (14) and diluent (15) at a determined volume ratio to a flame (12) in the combustion device; providing a flame stability sensor (30,40, 50) to generate a measurement of a characteristic of the flame, providing a flow measurement for each of the fuel and diluent, and controlling the determined volume ratio of fuel: diluent using the measurement from the flame stability sensor and/or flow measurements. A combustion system incorporating this method also is included.
Abstract:
A control system, and method for using the same, for controlling a boiler having a furnace is provided. The system includes at least one camera positioned in visual communication with a combustion chamber in a furnace. The camera is in communication with a controller and is operable to transmit signals indicative of a parameter of a flame within the furnace. Based at least in part on the received signals, the controller generates control adjustments for one or more of the boiler components. The control adjustments are communicated to the boiler components, which in turn are adjusted to optimize the performance of the boiler and reduce pollution.
