摘要:
A premix burner (200) which comprises a combustion head (210) comprising, in turn, a perforated covering element (220) provided with a plurality of openings (221). The premix burner is characterised in that it is provided with a device (205) for generating and delivering a minimum granted thermal power completely arranged inside the combustion head (210). Moreover, the device (205) comprises a concave element (260), whose concavity faces the internal wall of the perforated covering element (220).
摘要:
An apparatus, method and system is disclosed for a pilot light ignition system comprising: a fluid powered linear actuator; and a trigger member; wherein the linear actuator is configured to move the trigger member to triggering a spark generating mechanism to generate a spark for igniting a pilot light. The pilot light ignition system may be for use with, for example, a crude oil burner or gas flare.
摘要:
A portable device for testing the performance of an oxygen-depletion-sensing pilot light jet comprising a reservoir for containing a gas mixture which has an oxygen content just below the level at which the oxygen-depletion-sensing pilot light should safely operate, a gas mixture flow control means in communication or communicable with gas mixture applicator means; said applicator means in a first arrangement permitting said gas mixture to flow from said flow control means to atmosphere at ambient pressure and said applicator means including a supply duct locatable adjacent and/or over the air inlet aperture of an oxygen-depletion-sensing pilot light jet to supply said gas mixture thereto at ambient atmospheric pressure, or in a second arrangement said applicator means comprising a housing locatable to surround an oxygen-depletion-sensing pilot light jet and the air inlet aperture therefor and preferably also the ignition means for the pilot light, to enable supply said gas mixture to the air inlet aperture and to provide said gas mixture as a localised ambient environment to the pilot light.
摘要:
A modular ignition assembly for use in a direct fired make-up heater (10), having a hot surface igniter disposed adjacent the discharge ports of a pilot tube (24) for providing a pilot flame. The hot surface igniter is surrounded by a tubular shroud (34) for minimizing the effects of cold air and high humidity on the performance of the ignition assembly. A flame sensor (36) is provided for detecting and a sensing the existence of pilot flame and for controlling the gas flow to the burners accordingly.

Une butée d'appui 13 du berceau support d'un tube de veilleuse porte une rainure 15 comportant des parties usinées rectilignes destinées à coopérer avec des côtés latéraux usinés rectilignes du collet de positionnement du tube de veilleuse. Une nervure 19 s'étend horizontalement sur le côté des échancrures 12 et 14, entre la butée d'appui et un méplat supérieur 11. Application aux appareils de chauffage au gaz.
摘要:
A unit (20) mounted adjacent a main gas burner (11) comprising a gas supply tube (23) and a high voltage electrode (32') to form a spark gap of a high voltage gas ignition and flame proving system. Raw gas is supplied through the tube (23) to enrich the gas mixture around the spark gap (40) to a lower air to gas ratio than the air-gas mixture fed to the main burner.
