  2. Process duct work - Wikipedia

    en.wikipedia.org/wiki/Process_Duct_Work

    Rectangular ductwork is covered by the ASCE "The Structural Design of Air & Gas Ducts for Process Power Stations and Industrial Applications". In the practical design of primarily round structural process ductwork in the cement , lime and lead industries, the duct size involved ranges from 18 inches (45 cm) to 30 feet (10 m).

  3. Flue-gas desulfurization - Wikipedia

    en.wikipedia.org/wiki/Flue-gas_desulfurization

    The Pomorzany power plant in Poland also started up a similar sized unit in 2003 and that plant removes both sulfur and nitrogen oxides. Both plants are reported to be operating successfully. [17] [18] However, the accelerator design principles and manufacturing quality need further improvement for continuous operation in industrial conditions ...

  4. Air preheater - Wikipedia

    en.wikipedia.org/wiki/Air_preheater

    Instead the air ducts in the preheater are rotated so as to alternatively expose sections of the heating plate elements to the upflowing cool air. [1] [2] [3] As indicated in the adjacent drawing, there are rotating inlet air ducts at the bottom of the stationary plates similar to the rotating outlet air ducts at the top of the stationary ...

  5. Flue-gas stack - Wikipedia

    en.wikipedia.org/wiki/Flue-gas_stack

    A flue gas stack at GRES-2 Power Station in Ekibastuz, Kazakhstan, the tallest of its kind in the world (420 meters or 1,380 feet) [1]. A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air.

  6. Power plant engineering - Wikipedia

    en.wikipedia.org/wiki/Power_plant_engineering

    Cooling tower Nuclear power plant. Power plant engineering, abbreviated as TPTL, is a branch of the field of energy engineering, and is defined as the engineering and technology required for the production of an electric power station. [1] Technique is focused on power generation for industry and community, not just for household electricity ...

  7. Combined cycle power plant - Wikipedia

    en.wikipedia.org/wiki/Combined_cycle_power_plant

    A green hydrogen combined cycle power plant is only about 40% efficient, after electrolysis and reburning for electricity, and is a viable option for energy storage for longer term compared to battery storage. Natural gas power plants could be converted to hydrogen power plants with minimal renovation or do a combined mix of natural gas and ...

  8. Duct (flow) - Wikipedia

    en.wikipedia.org/wiki/Duct_(flow)

    Ducts commonly also deliver ventilation air as part of the supply air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. A duct system is also called ductwork. Planning (laying out), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design. [2]

  9. 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.
