Abstract

The present invention discloses a gas turbine energy saving type incoming gas anti-icing apparatus, provides improvement on the existing gas turbine air compressor inlet air anti-icing apparatus, and relates to the technical field of non-variable-capacity engines, heat exchange and pipeline systems. The gas turbine energy saving type incoming gas anti-icing apparatus is characterized in that the mixing heating device structure is that multi-row mixing heating alignment pipes (11) are aligned in a parallel manner, both ends of the mixing heating alignment pipes (11) are connected with connection boxes (10), one ends of the connection boxes (10) on both ends of the alignment pipes are communicated to form an n shape, the middle portion of the communication edge of the n-shaped connection box (10) is connected with a wind outlet pipe of an induced fan, the n-shaped connection box and the horizontal plane form downward inclination with an angle of 1-3 DEG along the air flow direction, and the lowest end bottom is provided with a tiny connection box low point drainage hole (12). According to the present invention, gas turbine unit power loss caused by the anti-icing system can be reduced, adverse effects of the anti-icing system on gas turbine unit operation stability can be reduced, and effects of anti-icing, frost prevention and energy saving are provided.

Description

technical field [0001] The invention is an energy-saving air intake anti-icing device for a gas turbine, which is an improvement to the existing air anti-icing device for the compressor inlet of the gas turbine. It relates to the technical fields of non-variable engine, heat exchange and pipeline system. Background technique [0002] As of the end of 2011, there were 113 combustion drive compressor units put into operation in CNPC's natural gas pipeline, mainly including RR units (27 units), GE units (63 units) and Solar units (21 units). Most of these units work in the central and western regions where the environment is relatively harsh. Especially under low temperature and high humidity working conditions, the moisture in the intake air may freeze, which will cause serious losses to the unit. There are many problems in the existing anti-icing measures of these units. For example, RR and GE units are equipped with compressor inlet air anti-icing systems that bleed air fro...
