Zusammenfassung: | The present invention provide a boiler. The boiler, which has a combustion chamber where a burner is installed and combustion reactions occur, comprises: a main heat exchanging unit which exchanges heat with combustion gases discharged from the combustion chamber to generate hot water; a steam generation unit which recovers waste heat from the exhaust gases which have passed through the main heat exchanger to generate steam; a steam supply unit which receives steam from the steam generation unit and supplies the steam to the burner; a condensing heat exchanging unit which cools the exhaust gases which have passed through the steam generator to condense moisture contained in the exhaust gases; a condensate collection unit in which the condensed water from the condensing heat exchanging unit is collected; and a condensate recovery unit which recycles the condensate collected in the condensate collection unit to the steam generation unit. Therefore, the boiler improves efficiency and reduces NOx emissions through the steam generation unit and the condensate recovery unit.
