Zusammenfassung:	PROBLEM TO BE SOLVED: To improve cooling efficiency, lifetime and assembly and disassembly of an impingement-cooled hot gas segment arrangement.SOLUTION: A hot gas segment arrangement includes a hot gas segment, which is removably mounted on a carrier and is subjected at its outside to hot gas and impingement-cooled at its inside. An impingement plate with a plurality of distributed impingement holes is arranged at a distance inside the hot gas segment. Cooling air supply means is provided for loading the impingement plate with pressurized cooling air in order to generate through the impingement holes jets of cooling air, which impinge on the inside of the hot gas segment. The impingement plate is part of a closed receptacle which is supplied with the pressurized cooling air, and the receptacle with the impingement plate is mounted on the carrier independently of the hot gas segment.
