Abstract
The purpose of the present invention is to decrease the loss of energy of flue gas when superheated steam is cooled and prevent heat efficiency from being decreased. A boiler is provided with: economizers (a medium-pressure economizer () and a high-pressure secondary economizer ()) which heat water supplied by water supply pumps (a medium-pressure water supply pump () and a high-pressure water supply pump ()); evaporators (a medium-pressure evaporator () and a high-pressure evaporator ()) which evaporate the water that is heated by the economizers; and cooling devices (a medium-pressure system and a high-pressure system) which mix water, as a coolant, which has passed through the economizers via the water supply pumps with steam.
