FIELD: power engineering.
SUBSTANCE: swirler to mix fuel and air, comprising multiple blades arranged on a dividing circumference, which, together with the first wall arranged on the first longitudinal end surface of the blades, and the second wall arranged on the opposite second longitudinal end surface of the blades, form a flow channel. The first wall has at least one injection hole that opens into the appropriate flow channel. The flow channel is formed so that air is mixed with fuel as it moves via the flow channel from the high pressure side to the low pressure side. Fuel may be additionally injected into the flow channel via at least one additional injection hole in the second wall. The invention supports homogeneous distribution of fuel in the flow channel.
EFFECT: even mixing of air with fuel, which results in even burning of a fuel and air mixture in a burner with low NOx emission.
