Abstract
Oppfinnelsen angår en fremgangsmåte til drift et gass- og dampturbinanlegg (1), i hvilket varme som foreligger i den ekspanderte arbeidsmedium (A1) og skaffet fra gassturbinen (2) benyttes til generering av damp for dampturbinen (10) i et vann-damp- kretsløp (12). Arbeidsmediet (A) for gassturbinen (2) genereres for forbrenning av et brensel (B, B1) ved tilførsel av komprimert luft (L). I henhold til oppfinnelsen blir for å øke anleggets effektivitet den genererte damp før den innføres i dampturbinen (10) overhetet ved hjelp av varme dannet under en hydrogen-oksygen-forbrenningsprosess. Koblet nedstrøms for gassturbinen (2) på spillgassiden omfatter installasjonen (1) en spillvarmedamp- generator som rommer et antall heteflater (20-28) anordnet i et vann-damp-kretsløp i dampturbinen (10). En hydrogen-oksygen-brenner (58) er anordnet mellom spillvarmedampgeneratoren (14) og dampturbinen (10) i vann-damp-kretsløpet (12).The invention relates to a method of operating a gas and steam turbine plant (1), in which heat present in the expanded working medium (A1) and obtained from the gas turbine (2) is used to generate steam for the steam turbine (10) in a water-steam system. circuit (12). The working medium (A) for the gas turbine (2) is generated for combustion of a fuel (B, B1) by the supply of compressed air (L). According to the invention, in order to increase the efficiency of the plant, the steam generated before it is introduced into the steam turbine (10) is superheated by heat formed during a hydrogen-oxygen combustion process. Connected downstream of the gas turbine (2) on the waste gas side, the installation (1) comprises a waste heat steam generator which accommodates a plurality of heat surfaces (20-28) arranged in a water-vapor circuit in the steam turbine (10). A hydrogen-oxygen burner (58) is arranged between the waste heat steam generator (14) and the steam turbine (10) in the water-steam cycle (12).
