TLDRThis video explains the functioning of turbo gas power plants, which generate electricity using diesel oil and natural gas. Unlike traditional steam power plants, these plants do not use an external boiler and don't need cooling water. Instead, they employ a gas turbine that converts thermal energy into mechanical energy, later transformed into electrical energy. Key components include a compressor that takes air, compresses it, and injects it into a combustion chamber along with fuel to generate heat. The resultant high-temperature gas drives a turbine, producing mechanical energy transmitted to an alternator, which generates electricity. The plant features lower construction and maintenance costs, and it rapidly constructs due to its simpler setup. Additionally, it uses natural gas, a cleaner fossil fuel option. The video details the plant's scheme, from compressor, combustion, to exhaust expulsion through chimneys, and the transformer's role in elevating voltage for high tension lines.

    This video explains the function of a gas turbine power plant, which differs from traditional thermal power plants by using diesel and natural gas as fuels. The plant consists of gas storage tanks, a machine room with a steam turbine, an alternator, and a transformer. Unlike traditional power plants that use external boilers, the gas turbine plant uses a gas turbine to convert heat into mechanical energy. The air is compressed and injected into a combustion chamber where fuel is burned. The hot air and gas mixture move the turbine blades, converting thermal energy into mechanical energy, which is then converted into electricity by the alternator. This plant is cost-effective, quick to build, and uses less polluting natural gas. Unlike thermal power plants, it does not require cooling water. The plant includes a compressor that draws in external air, a gas intake pipe for the combustion chamber, and exhaust chimneys for combustion byproducts. The alternator transforms rotational energy into electricity, and the transformer increases the voltage for high-voltage lines.

  • What fuels are used in a turbo gas power plant?

    Turbo gas power plants use diesel oil and natural gas as fuels.

  • How does a turbo gas power plant differ from traditional steam power plants?

    Unlike traditional steam power plants, turbo gas plants use a gas turbine instead of an external boiler and do not require cooling water.

  • What is the main advantage of using natural gas in turbo gas power plants?

    Natural gas is the least polluting fossil fuel, which makes turbo gas power plants more environmentally friendly compared to others using different fossil fuels.

  • How is the conversion of energy accomplished in a turbo gas power plant?

    Air is compressed and mixed with fuel in the combustion chamber, where it burns. The resulting high-temperature gas drives a turbine, converting thermal energy into mechanical energy, which is then converted into electrical energy by an alternator.

  • What are the benefits of a turbo gas power plant?

    Turbo gas power plants have lower construction and maintenance costs, are simpler and faster to build, and do not require cooling water.

  • What role does the transformer play in a turbo gas power plant?

    The transformer increases the voltage of the electricity generated before it is transmitted through high-voltage lines.

  • How does the combustion process work in a turbo gas power plant?

    Fuel is combusted in a high-pressure environment to release heat, which is used to drive a turbine and generate electricity.

  • What happens to the exhaust gases in a turbo gas power plant?

    The exhaust gases are expelled through tall chimneys as smoke.

  • 00:00:00
    buongiorno a tutti con questo video
  • 00:00:02
    cerchiamo di capire come funziona una
  • 00:00:05
    centrale a turbogas le centrali a
  • 00:00:09
    turbogas si differenziano da quelle
  • 00:00:12
    termoelettriche perché per produrre
  • 00:00:14
    energia elettrica usano come
  • 00:00:16
    combustibili il gasolio e il gas metano
  • 00:00:20
    esse si presentano in questo modo
  • 00:00:24
    abbiamo innanzitutto una prima zona di
  • 00:00:27
    stoccaggio del gas all'interno di
  • 00:00:30
    serbatoi pressurizzati una sala macchina
  • 00:00:35
    dove possiamo trovare la turbina a
  • 00:00:39
    vapore e l'alternatore turbina a vapore
  • 00:00:45
    e alternatore ed infine il trasformatore
  • 00:00:56
    eccolo qui il trasformatore la centrale
  • 00:01:00
    a turbogas a differenza delle centrali a
  • 00:01:04
    vapore da tradizionali non impiega una
  • 00:01:07
    caldaia esterna ma una turbina a gas
  • 00:01:10
    cioè una macchina rotativa termica che
  • 00:01:18
    converte il calore il lavoro l'aria
  • 00:01:26
    aspirata
  • 00:01:27
    dal compressione dal compressore viene
  • 00:01:31
    compressa e immessa nella camera di
  • 00:01:34
    combustione in cui il combustibile
  • 00:01:36
    gasolio o gas metano viene bruciato la
  • 00:01:44
    miscela di aria e gas ad alta
  • 00:01:48
    temperatura viene inviata direttamente
  • 00:01:50
    sulle pale di una turbina dove avviene
  • 00:01:54
    la conversione dell'energia termica in
  • 00:01:56
    energia meccanica la quale dopo esser
  • 00:02:01
    stata trasmessa all'alternatore permette
  • 00:02:05
    di produrre energia elettrica
  • 00:02:16
    questo tipo di impianto presenta diversi
  • 00:02:18
    vantaggi tra cui i costi ridotti di
  • 00:02:21
    costruzione e mantenimento oltre a
  • 00:02:23
    semplicità e rapidità di costruzione
  • 00:02:26
    inoltre a differenza delle centrali
  • 00:02:28
    termoelettriche non necessita dell'acqua
  • 00:02:31
    di raffreddamento per trasformare il
  • 00:02:33
    vapore in acqua infine impiega il gas
  • 00:02:37
    metano che è il meno inquinante tra i
  • 00:02:40
    combustibili fossili
  • 00:02:43
    guardiamo ora come si presenta lo schema
  • 00:02:45
    dell'impianto abbiamo il compressore il
  • 00:02:51
    compressore allo scopo di prelevare
  • 00:02:53
    l'area l'area dall'ambiente esterno e
  • 00:02:56
    iniettarla ad alta pressione nella
  • 00:02:59
    camera di combustione
  • 00:03:03
    questo invece rappresenta la tubazione
  • 00:03:07
    che consente l'ingresso del gas
  • 00:03:10
    all'interno della camera di combustione
  • 00:03:14
    nella camera di combustione avviene
  • 00:03:17
    appunto la combustione vera e propria
  • 00:03:19
    del gas sprigionando ha una elevata
  • 00:03:22
    quantità di calore la turbina a gas si
  • 00:03:29
    presenta in questo modo l'energia
  • 00:03:31
    chimica della combustione viene
  • 00:03:34
    immediatamente utilizzata dalla turbina
  • 00:03:37
    a gas per generare l'energia
  • 00:03:40
    manica di rotazione i gas di scarico
  • 00:03:46
    ovvero i sottoprodotti della reazione di
  • 00:03:50
    combustione vengono allontanati
  • 00:03:53
    attraverso delle alte ciminiere sotto
  • 00:03:57
    forma di fumi l'alternatore poi è
  • 00:04:03
    l'organo che trasforma l'energia
  • 00:04:05
    meccanica di rotazione in energia
  • 00:04:08
    elettrica
  • 00:04:09
    poi c'è il trasformatore tramite i
  • 00:04:14
    trasformatori la tensione viene alzata a
  • 00:04:17
    migliaia di volte prima di essere
  • 00:04:20
    immessa sulle linee di alta tensione
