Abstract
A boiler system has a boiler and a combustion amount control unit. The boiler includes a boiler body, a discharge unit, a discharge passage, a feedwater preheater and a feedwater temperature measuring unit. The feedwater preheater includes a heat exchanger. The feedwater temperature measuring unit measures a feedwater temperature that is the temperature of the feedwater flowing in the heat exchanger. The combustion amount control unit controls combustion amount in the boiler, and has a feedwater temperature threshold as a threshold relating to the feedwater temperature. The combustion amount control unit minimizes the combustion amount in the boiler in a case where the feedwater temperature measured by the feedwater temperature measuring unit is the feedwater temperature threshold or lower.
