  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. 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 .

  4. 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.

  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. Combustion chamber - Wikipedia

    en.wikipedia.org/wiki/Combustion_chamber

    In an internal combustion engine, the pressure caused by the burning air/fuel mixture applies direct force to part of the engine (e.g. for a piston engine, the force is applied to the top of the piston), which converts the gas pressure into mechanical energy (often in the form of a rotating output shaft). This contrasts an external combustion ...

  7. Gas burner - Wikipedia

    en.wikipedia.org/wiki/Gas_burner

    Propane burner used with forced air into a metal melting furnace. 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 ...

  8. Pulverized coal-fired boiler - Wikipedia

    en.wikipedia.org/wiki/Pulverized_coal-fired_boiler

    The burner mixes the powdered coal in the air suspension with additional pre-heated combustion air and forces it out of a nozzle similar in action to fuel being atomized by a fuel injector in an internal combustion engine. Under operating conditions, there is enough heat in the combustion zone to ignite all the incoming fuel. [citation needed]

  9. Inerting system - Wikipedia

    en.wikipedia.org/wiki/Inerting_system

    After being fully filled, and during use, there is a space above the fuel, called the ullage, that contains evaporated fuel mixed with air, which contains the oxygen necessary for combustion. Under the right conditions this mixture can ignite. An inerting system replaces the air with a gas that cannot support combustion, such as nitrogen. [1] [2]
