FIELD: heat power engineering.
SUBSTANCE: invention relates to heat power engineering, namely to the device of gas burners for preliminary mixing of combustible gases. The gas modulation burner of complete premixing contains a cylindrical body, muffled on one side and attached to the flange of the body on the other side, the forming surface of the burner body is made with holes for the gaseous fuel mixture to exit. The body is divided by an internal partition into two internal zones, the work of one of which can be performed separately, the partition is connected to the cylinder and made with the possibility of longitudinal movement along the burner axis, a valve with a rod is installed in the internal partition, which ensures the passage of the gaseous fuel mixture between the inner zones of the cylindrical body.
EFFECT: invention makes it possible to ensure stable operation in a wide range of changes in the thermal power of the heat-generating device.
