A boiler including one or more evaporators, an economizer, and a low-temperature heat exchanger. The economizer is located on a downstream side of the most downstream evaporator which is an evaporator at the most downstream side among the one or more evaporators. The low-temperature heat exchanger is located on the downstream side of the economizer, has an inlet for receiving water from the outside, and is configured to heat the water introduced from the inlet and sent to the economizer with the combustion gas.

Boiler, steam-generating plant provided with same, and method for operating boiler

An exhaust gas latent-heat recovery device includes: a heat transfer tube disposed inside a duct through which exhaust gas flows, the heat transfer tube having a water supply inlet into which water to be heated for recovering latent heat of the exhaust gas is supplied and a water supply outlet through which the water to be heated is discharged; and a water supply control part configured to control supply of the water to be heated to the water supply inlet. The water supply control part is configured to control supply of the water to be heated from the water supply inlet so that an outlet temperature being a temperature of the water to be heated at the water supply outlet is at a set temperature.
