Embodiment Construction
[0026] In order to understand the present invention more clearly, the present invention will be described in further detail below in conjunction with accompanying drawing:
[0027] The following are the system connection schematic diagrams for the two air heating schemes, among which scheme 1 is as follows figure 1 As shown, scheme 2 is as figure 2 shown.
[0028] For the two schemes, the following system connection methods are the same, see figure 1 , figure 2 : The steam outlet of the boiler is connected to the steam inlet of the steam turbine, and the exhaust steam at the outlet of the steam turbine is connected to the condenser, and the condensed water at the outlet of the condenser passes through the condensate pump, the low-pressure heater, the deaerator, the feed water pump, and the high-pressure heater in sequence Going back to the feed water inlet of the boiler, the steam extraction ports of different parameters on the steam turbine are respectively connected to th...
