HEATER Russian patent published in 2009 - IPC F23D14/20 

FIELD: heating.

SUBSTANCE: invention relates to power, transport and chemical machinery engineering and may be used in gas and turbine plants. The specified technical result is achieved by the burner design including outer cylindrical shell and vane air swirler with vanes and bushing. The vane swirler is co-axial to the above shell. The swirler bushing forms annular pre-chamber together with the aforesaid outer shell. There is a fuel-distributing unit in the pre-chamber behind the vanes in air movement direction. The fuel distributing unit is represented with, at least, one annular line of pipes with openings being distributed along the pipe length to supply fuel to the pre-chamber. According to the invention, the pipes are parallel to the burner axis, and pipe length is defined to the ratio of geometric characteristics of the burner.

EFFECT: improvement of environmental characteristics and operational reliability of gas and turbine plant.
