Vapor generator for actuating revolving machine e.g. steam turbine, has one combustion hearth with boiler and vaporization zone, and another hearth with another boiler and over heat zone
The generator (10) has two combustion hearths (F1,F2) in which a fuel is burnt with an oxidant. A combustion hearth has a boiler (12) and a vaporization zone (V) including a vaporization exchanger (20). The other hearth has another boiler (24) and an over heat zone (S1) including an over heat exchan...

Summary: | The generator (10) has two combustion hearths (F1,F2) in which a fuel is burnt with an oxidant. A combustion hearth has a boiler (12) and a vaporization zone (V) including a vaporization exchanger (20). The other hearth has another boiler (24) and an over heat zone (S1) including an over heat exchanger (30). An exit of over heat zone communicates with an envelope having a preheat that includes an economizer.
La présente invention concerne un générateur de vapeur comprenant un foyer de combustion, au moins un brûleur alimenté en combustible et en comburant, une zone de vaporisation comprenant un échangeur de vaporisation, une zone de surchauffage comprenant un échangeur de surchauffage, une zone de préchauffage comprenant un échangeur de préchauffage et un ballon collecteur.Selon l'invention, le générateur comprend au moins deux foyers de combustion (F1, F2) successifs et chaque foyer comprend au moins un échangeur (20, 30, 38, 78, 40) d'au moins une desdites zones (V, V1, V2, V3, V4; S1, S2, S3; P). |
