Supporting device of denitration equipment of gas turbine unit

The invention discloses a supporting device of denitration equipment of a gas turbine unit. The supporting device comprises a gas turbine unit denitration catalyst supporting device and a gas turbineunit denitration ammonia spraying grid supporting device, wherein the gas turbine unit denitration ammonia spraying grid supporting device comprises a first inner frame, a first outer frame, a plurality of first limiting supports and a plurality of anti-collision beams. The gas turbine unit denitration catalyst supporting device comprises a second outer frame, a second inner frame, a hanging plateand a plurality of second limiting supports. The second inner frame is fixed to the inner side of the second outer frame through thesecond limiting supports. According to the device, the problems ofammonia spraying grids and catalyst supporting in the narrow space of the heating surface of the waste heat boiler are solved, the structural temperature stress is eliminated, and the heat loss of theboiler is reduced. 本发明公开了一种
