ÖNORM EN 45510-5-2

This standard gives guidance on writing the technical specification for the procurement of gas turbines, including gas turbines for combined-cycle systems, and their auxiliaries for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide. This Guide is applicable to open-cycle gas turbines using normal combustion systems, generally greater than 20 MW electrical output, and also includes closed-cycle, semi closedcycle and combined-cycle gas turbine power piants and combined heat and power plants. In cases of turbines using free piston gas generators or special heat sources (for example, chemical process, nuclear reactors, furnace for a super-charged boiler), this Guide may be used as a basis but will need to be suitabfy modified. This Guide excludes gas turbines for marine propulsion and those used to propel aircraft, locomotives, military vehicles, road construction and earth-moving machines, agricultural and industrial types of tractors and road vehicles. This Guide for Procurement of Gas Turbines has been prepared to be used with the existing International Standard ISO 3977. It should, therefore, be read in addition and complementary to the International Standard. The equipment covered by this Guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated in performance terms rather than being specified by a defailed description of the equipment to be supplied. This Guide indicates to potential purchasers how their specification should be prepared so that: the equipment type and capacity intetfaces corectly with other elernents of the systems; predicted performance is achieved; ancillary equipment is propedy sized; reliability, availab (...abbreviated)
