  2. Auto reignition - Wikipedia

    en.wikipedia.org/wiki/Auto_reignition

    Most gas ranges and cooktops use sparking devices to ignite the burner flame. This eliminates the need for a pilot flame , which wastes energy. Most of these sparking device-equipped ranges require the user to control the ignition sparking manually, resulting in a three-step process required to operate the burner:

  3. Ignition system - Wikipedia

    en.wikipedia.org/wiki/Ignition_system

    Ignition systems are used by heat engines to initiate combustion by igniting the fuel-air mixture. In a spark ignition versions of the internal combustion engine (such as petrol engines), the ignition system creates a spark to ignite the fuel-air mixture just before each combustion stroke. Gas turbine engines and rocket engines normally use an ...

  4. Autoignition temperature - Wikipedia

    en.wikipedia.org/wiki/Autoignition_temperature

    The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

  5. HVAC control system - Wikipedia

    en.wikipedia.org/wiki/HVAC_control_system

    HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

  6. Gas heater - Wikipedia

    en.wikipedia.org/wiki/Gas_heater

    A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or non-flued, or vented and unvented .

  7. Flame lift-off - Wikipedia

    en.wikipedia.org/wiki/Flame_lift-off

    Flame lift-off in oil fired pressure jet burners is an unwanted condition in which the flame and burner become separated. This condition is most commonly created by excessive combustion air and often results in the loss of flame as the photoelectric cell fails to register the light of the flame, this in turn results in a safety lockout of the control box.

  8. Gas burner - Wikipedia

    en.wikipedia.org/wiki/Gas_burner

    Propane burner with a Bunsen flame Oxy-Acetylene for cutting through steel rails Flame of a gas and oil, in a dual burner A gas burner is a device that produces a non-controlled flame by mixing a fuel gas such as acetylene , natural gas , or propane with an oxidizer such as the ambient air or supplied oxygen , and allowing for ignition and ...
