Abstract
The invention relates to an injection device (10) for atomizing a liquid into droplets using a gas, comprising a hollow tubular body (12) having a longitudinal direction (X). An inner wall (13) defines a first region, referred to as contact region (Z1), and a second region (Z2). The body includes: —at least two inlet ports (14; 16) for injecting liquid and an inlet port for injecting gas, all of said ports extending to the first region (Z1); —at least one outlet port (18), located downstream of the first and second regions, for discharging the atomized liquid. The body (12) has an inner cross-section that varies continuously or constantly over the entire length thereof. Between regions (Z1) and (Z2), the inner wall (13) includes at least one baffle (261) which is shaped such that in each plane running perpendicularly to the longitudinal direction of the body containing said baffle, the baffle reduces an inner cross-section of the body over the entire periphery of the inner wall (13).
