Summary:A lean-burn combustor (16) includes: a plurality of lean-burn fuel injectors (50), each comprising a fuel supply arm (52) and a lean-burn fuel injector head (54) with a lean-burn fuel injector head tip (72), where the lean-burn fuel injector head tip has a lean-burn fuel injector head tip diameter (d), the lean-burn fuel injector head comprises a pilot fuel injector and a main fuel injector, the main fuel injector being arranged coaxially and radially outward with the pilot fuel injector; and a combustor chamber (60) extending in an axial direction (62) and including a radially inner annular wall (64), a radially outer annular wall (66) and a metering plate (68) defining a size and shape of the combustor chamber, where the combustor chamber includes a primary combustion zone (80) and a secondary combustion zone (82) having a primary combustion zone depth (D). The ratio D/d of the primary combustion zone depth to the lean-burn fuel injector head tip diameter is less than 2.4. 一种稀燃燃烧器（16），包括：多个稀燃燃料喷射器（50），每个稀燃燃
