METHOD FOR OPERATING A BOILER WITH FORCED CIRCULATION AND BOILER FOR ITS IMPLEMENTATION

The invention concerns a boiler comprising at least a first heat exchanger (10) with its inlet connected to a water supplying duct (18) and its outlet connected, through a first regulating valve (30) to a steam turbine, either directly, or through a second heat exchanger (12). During the starting ph...

Summary:The invention concerns a boiler comprising at least a first heat exchanger (10) with its inlet connected to a water supplying duct (18) and its outlet connected, through a first regulating valve (30) to a steam turbine, either directly, or through a second heat exchanger (12). During the starting phase the regulating valve (30) is closed and as long as the fluid at the first heat exchanger (10) outlet is a mixture of water and steam, all the water is transformed into steam by condensation and the regulating valve (30) is opened only when the fluid at the first evaporator outlet is pure steam. La chaudière comporte au moins un premier échangeur de chaleur (10) dont l'entrée est reliée à une conduite d'alimentation en eau (18) et dont la sortie est reliée, à travers une première vanne de réglage (30) à une turbine à vapeur, soit directement, soit à travers un second échangeur de chaleur (12). Pendant la phase de démarrage la vanne de réglage (30) est fermée et aussi longtemps que le fluide à la sortie du premier échangeur (10) est un mélange d'eau et de vapeur, on transforme, par condensation, toute la vapeur en eau et on n'ouvre la vanne de réglage (30) que lorsque le fluide à la sortie du premier évaporateur est de la vapeur pure.
