  2. LO-NOx burner - Wikipedia

    en.wikipedia.org/wiki/LO-NOx_burner

    Therefore John Joyce's research into low NO x burners revolved primarily around surface combustion techniques. Another issue was the effect combustion temperatures have on the formation of NO x . John Joyce's task became even more challenging when he decided not to direct his development towards radiant type surface combustion tiles.

  3. Staged combustion - Wikipedia

    en.wikipedia.org/wiki/Staged_combustion

    Another method of fuel staged combustion is fuel biasing. In fuel biasing, combustion is staged by diverting fuel from the upper-level burners to the lower ones or from the center to the side burners. The aim is to create a fuel-rich lower or central zone and a fuel-lean upper or side zone in order to achieve complete burnout.

  4. Dry low emission - Wikipedia

    en.wikipedia.org/wiki/Dry_Low_Emission

    The amount of NOx produced depends on the combustion temperature. [2] When the combustion takes place at a lower temperature the NOx emissions are reduced. [2] Gas turbines with DLE technology were developed to achieve lower emissions without using water or steam to reduce combustion temperature (Wet Low Emission (WLE) technology).

  5. Combustor - Wikipedia

    en.wikipedia.org/wiki/Combustor

    It is also known as a burner, burner can, combustion chamber or flame holder. In a gas turbine engine, the combustor or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands.

  6. Thermal oxidizer - Wikipedia

    en.wikipedia.org/wiki/Thermal_oxidizer

    Preassembled process unit for air pollution control, i.e., a thermal oxidizer, being installed at a work site. Schematic of a basic thermal oxidizer A thermal oxidizer (also known as thermal oxidiser , or thermal incinerator ) is a process unit for air pollution control in many chemical plants that decomposes hazardous gases at a high ...

  7. Lean-burn - Wikipedia

    en.wikipedia.org/wiki/Lean-burn

    The main drawback of lean-burning is that a complex catalytic converter system is required to reduce NOx emissions. Lean-burn engines do not work well with modern 3-way catalytic converter—which require a pollutant balance at the exhaust port so they can carry out oxidation and reduction reactions—so most modern engines tend to cruise and ...

  8. Heat recovery steam generator - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_steam_generator

    Some HRSGs include supplemental, or duct firing. These additional burners provide additional energy to the HRSG, which produces more steam and hence increases the output of the steam turbine. Generally, duct firing provides electrical output at lower capital cost. It is therefore often utilized for peaking operations.

  9. Organic Rankine cycle - Wikipedia

    en.wikipedia.org/wiki/Organic_Rankine_cycle

    T-s diagram for the ideal/real ORC. The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, [3] screw, [4] scroll, [5] or other expander), and then through a condenser heat exchanger where it is finally re-condensed.
