Document Type and Number:
WIPO Patent Application WO/2023/030467
Kind Code:
A1
Abstract:
Disclosed in the present invention are a combustion chamber having double fuel pipes and a gas turbine. The combustion chamber comprises a flame tube, an igniter, a first swirler, a second swirler, a first fuel pipe, a second fuel pipe, and a housing; an inner cavity of the flame tube is sequentially divided into a primary combustion area, a secondary combustion area, and a mixing area from front to back; a plurality of mixing holes are formed in the side wall of the mixing area; the second swirler is provided at the front end of the flame tube and is coaxial with the flame tube; the first swirler is provided on a portion, close to an outlet end, in an inner hole of the second swirler and is coaxial with the second swirler; a gap is reserved between the outer side wall of the first swirler and the inner hole of the second swirler; the first fuel pipe penetrates through the front wall of the flame tube and is communicated with the first swirler; the second fuel pipe penetrates through the front wall of the flame tube and is communicated with the second swirler; the igniter extends into the primary combustion area from the side wall of the flame tube; the housing covers the flame tube; and an air channel is provided between the flame tube and the housing. According to the present invention, the double fuel pipes and the double swirlers are used, such that the fuel gas is fully mixed, and the fuel is fully and continuously combusted, thereby reducing the emission.
