Abstract
The present invention provides a novel turbo-generator unit, which at least comprises a boiler and a superheater and a reheater provided in the boiler. On the boiler, the positions corresponding to the header of the steam inlets and outlets of the superheater and reheater form the header-connection area; the steam pipe system at least comprises the pipes that connect the boiler with the HP cylinder and the IP cylinder and are used to transmit the HTHP steam; the HP cylinder and the generator constitute the high-level shafting, and the high-level shafting is positioned outside of boiler and close to the header-connection area. The present invention can also comprise a low-level shafting positioned at a low level. Since the high-level shafting and the low-level shafting are arranged at different levels, the lengths of costly HTHP steam pipes in the pipe system and the pressure drop and heat radiation loss of the pipe system are significantly reduced, and the work capability of the unit is improved. Furthermore, the quantity of the steam stored in the reheat system and the adjustment inertia of unit is reduced, and the economical efficiency of the double-reheat unit is sufficiently realized.
