摘要： A method of optimizing operation of a furnace to control emission within a system. Each furnace zone inside of the furnace is associated with at least one exhaust zone. A signal indicative of an amount of byproduct exiting the furnace through at least one of the exhaust zones is received from one or more of the sensors. Based on this signal, an offending furnace zone is identified from among the plurality of furnace zones, the offending furnace zone including an oxygen level contributing to the amount of the byproduct. A relative adjustment of at least one of an amount of oxygen being introduced into the offending furnace zone, and an angular orientation of an oxygen injector introducing oxygen into the offending furnace zone relative to a focal region within the furnace can be initiated. The furnace may have structure to perform the method and may be part of a system.

Dies wird mit einer Strahlheizvorrichtung (1) für eine Ofenanlage erreicht, bei der eine Überwachungseinrichtung zur Ermittelung eines aktuellen Druckes in der Verbrennungsluftleitung (8) und/oder in der Verbrennungsgasleitung (10) unmittelbar vor Eintritt in das Gehäuse des zumindest einen Brenners (2) vorgesehen ist, die den aktuell ermittelten Druck an eine Brennersteuerung (5) ausgibt. Dabei ist die Überwachungseinrichtung und/oder die Brennersteuerung (5) derart ausgestaltet, dass sie den aktuell ermittelten Druck mit einem vorbestimmten Grenzwert vergleicht und/oder sie eine aus einem aktuell ermitteltem Druck und einem Druck einer korrespondierenden Sammelleitung gebildete Druckdifferenz Δp mit einem vorbestimmten Grenzwert vergleicht. Die Überwachungseinrichtung und/oder die Brennersteuerung (5) gibt ferner ein eine Undichtigkeit des keramischen Strahlheizrohres (3) anzeigendes Signal aus, wenn der aktuell ermittelte Druck den vorbestimmten Grenzwert unterschreitet und/oder wenn die aus aktuell ermitteltem Druck und einem Druck einer korrespondierenden Sammelleitung gebildete Druckdifferenz Δp einen vorbestimmten Grenzwert überschreitet.

摘要： An exhaust pressure control apparatus is disclosed. The exhaust pressure control apparatus including a main body in which an inlet port and an outlet port are formed, the main body also including a pilot chamber. The system also includes a spool comprising an upper slide and a lower slide, the upper slide forming a movable portion of the pilot chamber, and the spool is held by the upper slide and the lower slide so that it can slide in an axial direction over a sliding surface connecting the intake port and the discharge port. A control system regulates a pressure in the intake port by controlling a pressure regulating gas supplied to the pilot chamber, and a control status portion provides an indication of the stability of the control system based upon the pressure in the pilot chamber.

摘要： The invention relates to a method for controlling the combustion air supply in a steam generator that is fueled with fossil fuels, the combustion air being supplied gradually in different combustion zones. The invention is characterized in that combustion air supply is controlled, depending on the NOx and/or CO content in the flue gas, in such a manner that first the air supply is varied between the different combustion zones with approximately constant air volumes. An external control of the overall air volume overrides this type of control.

摘要： A specific electrode arrangement for a burner already exists with which the flame of the burner is influenced by using electrical fields, whereby these electrical fields pass through only areas of the flame in which a stabilizing and pollutant-reducing action occurs. According to the invention, the electrodes used to this end simultaneously serve both as probes for detecting flame properties as well as active field electrodes for influencing the flame properties. The probe signals can react to the voltage applied in an inertia-free manner to the electrodes without the involvement of mechanical elements. According to the associated device equipped with a burner and associated electrodes and with a power supply unit (16), the power supply unit (16) furnishes a voltage (U(t)) that varies over time, and at least one measuring transducer (17, 17') exists that detects the current generated in the flame (13) by the voltage between both electrodes (12, 14) and provides feedback to the power supply unit (16) after amplification.

摘要： Es wird ein Verfahren zur Anpassung eines brennerbeheizten Heizgerätes an ein diesem zugeordneten Luft-/Abgassystem vorgeschlagen, das ein Gebläse für Verbrennungsluft, ein Steuergerät und eine Gasdosiereinrichtung für Brenngas sowie eine mit dem Steuergerät in Verbindung stehende Differenzdruckmessstelle umfasst. Das Gebläse ist in Abhängigkeit von der Wärmeanforderung durch das Steuergerät steuerbar, wobei die Drehzahl des Gebläses zumindest bei Inbetriebnahme des Heizgerätes kontinuierlich gesteigert wird, bis im Schaltpunkt der Differenzdruckmessstelle eine Schaltdrehzahl für einen erforderlichen Luftvolumenstrom ermittelt wird. Im Steuergerät wird ein Kennfeld von Gebläsekennlinien (71, 72, 73, 74) abgelegt, die jeweils einer bestimmten Schaltdrehzahl n x zuordenbar sind. Anhand der ermittelten Schaltdrehzahl n x wird aus dem Kennfeld von Gebläsekennlinien (71, 72, 73, 74 eine Gebläsekennlinien K x als Betriebskennlinie ausgewählt, nach der das Heizgerät arbeitet.
