    It is the amount of energy that is still available from the ash of from the fuel that is burn

    Burning efficiency

  • 81

    It is the process of converting a solid carbon into combustible carbon monoxide by thermal chemical reaction of a fuel

    Gasification

  • 82

    The process takes place with excess air

    Combustion

  • 83

    The process takes place with excess carbon

    Gasification

  • 84

    Process of solid fuel containing carbon in accomplished in an air, sealed close chamber, under light suction, or pressure relative ambient pressure

    Gasification

  • 85

    Explain the principle of gasification

    In classification the process takes place with excess carbon, and the limited amount of air is introduced to the reactor of the gas passes through the fuel column

  • 86

    It is the ratio of the amount of stomatic air needed to gasify fuel

    Equivalence ratio

  • 87

    What is the equivalent ratio of gasification process?

    0.2–0.4

  • 88

    It is a very old technology usually used used for small scale application, where agree residues, as fuel requires densification, which will add cause
