  • Publication number: 20220412557
    Abstract: The present disclosure relates to apparatuses and methods that are useful for one or more aspects of a power production plant. More particularly, the disclosure relates to combustor apparatuses and methods for a combustor adapted to utilize different fuel mixtures derived from gasification of a solid fuel. Combustion of the different fuel mixtures within the combustor can be facilitated by arranging elements of the combustor controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel mixtures.
    Type: Application

  • Patent number: 6178737
    Abstract: The present invention provides a valve and a low pressure drop combustor bypass. The valve simultaneously controls both the supply of air to the premixer and the amount of air directed into a large bypass duct. Air entering the bypass duct is reintroduced into the gas flowpath as dilution air downstream of the combustion zone. At low power settings the valve directs most of the air to the bypass duct, in effect bypassing the fixed area dilution ports, whereby the pressure drop across the combustor may be controlled at an optimal level.
