摘要:
Disclosed is a burner comprising a fuel providing part configured to provide a fuel for a combustion reaction; an air providing part configured to send air for the combustion reaction; an ignition part configured to cause a spark such that the fuel and air provided are ignite; and a processor electrically connected to the fuel providing part, the air providing part, and the ignition part, wherein the processor is configured to: control the fuel providing part and the ignition part to provide the fuel for ignition and cause the spark; and control the air providing part such that an flow rate of the air provided at an ignition time point, at which the spark is caused and ignition occurs, is lower than a flow rate of the air provided at an air provision time point corresponding to a specific delay time after the ignition time point.

Apparatus for igniting fuel in a combustor (10) includes an injector (30) having an electrostatic fuel atomisation nozzle (50) and an igniter (52). The injector (30) produces an initial combustion process which ignites the main fuel supply from a fuel nozzle (16). Alternatively, a main fuel nozzle is provided which includes a plurality of electrostatic fuel nozzles disposed about a centrally located igniter. The igniter may be a laser igniter.
摘要:
Bei einem Verdampferbrenner für Standheizungen für Kraftfahrzeuge entstand früher nach Abschalten der Brennstoffzufuhr und dem anschließenden Abreißen der Flamme störender Blaurauch, da Restbrennstoff lediglich erwärmt, nicht jedoch verbrannt wurde. Erfindungsgemäß wird nach dem Abschalten der Brennstoffzufuhr (B) die Glühkerze (3) für eine bestimmte Zeitspanne während der Nachlaufphase des Verbrennungsluftgebläses eingeschaltet. Dadurch wird praktisch jeglicher Restbrennstoff verdampft und verbrannt und somit eine Bildung von Blaurauch sowie die Bildung von bleibenden Verbrennungsrückständen im Bereich des Kerzenstutzens und/oder des Brenners vermieden.

Die Erfindung betrifft ein Verfahren zum Betrieb einer Vergasungsbrenner/Heizkesselanlage, bei dem aus der Aussenlufttemperatur die erforderliche Brennerleistung ermittelt und dann in Abhängigkeit von der geforderten Brennerleistung die Massenströme von Heizöl und Luft gesteuert werden, wobei Abweichungen vom stöchiometrischen Verhältnis zwischen Heizöl und Luft mittels einer im Abgasstrom angeordneten λ-Sonde (30) geregelt werden.

A method for turning an atomizing burner from an ON state to an OFF state is provided. The burner has independently controllable flows of atomizing air, combustion air, and fuel flow, the burner in the ON state having flow values of burner parameters including flow of atomizing air, flow of combustion air, and fuel flow. The method includes: changing, in response to an OFF instruction, flow of at least one of the flow of atomizing air, combustion air and/or fuel to a lower non-zero value; first discontinuing, after a first period of time since the changing, flow of fuel and flow of atomizing air; maintaining, for a second period of time since the first period of time, flow of combustion air; second discontinuing, after the maintaining, flow of combustion air; wherein the maintaining prevents buildup of excess heat inside the burner during the transition to the OFF state.

A pilot and burner assembly includes a burner assembly and a blower for supplying combustion air to the burner assembly. The system further includes a pilot assembly and a fuel supply for providing fuel to the pilot assembly. A pilot fan provides pilot air to the pilot assembly, the pilot fan being separate from the blower and provides air only to the pilot assembly.
