The invention discloses a double-zone
combustor and a
combustion method thereof, and belongs to the technical field of
combustor equipment.The double-zone
combustor comprises a
combustion chamber casing, a first fuel inlet and a first blade swirler are arranged on one side of the interior of the
combustion chamber casing, and a second fuel inlet and a second blade swirler are arranged at the position, close to the middle, of the interior of the
combustion chamber casing; the area between the first blade swirler and the second blade swirler is a pre-combustion area, the area on the side, away from the pre-combustion area, of the second blade swirler is a main combustion area, the main combustion area is communicated with the pre-combustion area, and a fuel outlet is formed in the side, away from the first fuel inlet, of the interior of the
combustion chamber case. Through the double-area configuration of the pre-combustion area and the main combustion area, stable ignition and
flame stability are ensured through
methane, which is crucial for starting combustion, the
hydrogen supply main area can reduce the oil-gas ratio to the greatest extent, the efficiency is improved, the emission of
nitrogen oxides and
carbon dioxide is remarkably reduced, and the special area separation is realized, so that the
energy consumption is reduced. Independent control of fuel types is maintained.
