INLET BLEED HEATER FOR COMPRESSOR AND METHOD FOR PROVIDING INLET BLEED HEATER TO ELECTRICITY-GENERATING SITE

摘要

PURPOSE: An inlet bleed heater for a compressor and a method for providing the inlet bleed heater to an electricity-generating site are provided to secure an inlet bleed heat system capable of being fabricated at a fabrication site and transported to an electricity-generating site. CONSTITUTION: An inlet bleed heater for a compressor comprises a housing defining an air inlet duct for delivering ambient air along a flow path to the compressor; plural tubes(20) in the flow path of the air inlet duct; and a manifold(34) supported by the housing for supplying the extraction air from the compressor to the tubes. The tubes are adapted for receiving heated extraction air from the compressor. Each tube includes plural apertures spaced from one another for discharging the heated air from the tubes into the flow path for the mixing with the ambient inlet air passing through the tubes to supply heated air to the compressor. The manifold and each of the tubes are connected to one another by a bellows(53) enabling relative movement between the manifold and the tubes in response to thermally induced forces.
