A marine boiler (2, 54, 56, 58, 60, 68, 74) for transferring heat from exhaust gases (EG1, EG2) to a medium in the form of boiler water for generating steam on a vessel and a method of operating such a marine boiler are provided. The marine boiler (2, 54, 56, 58, 60, 68, 74) comprises a vessel (8, 78), an exhaust gas inlet (26, 98) for receiving exhaust gas (EG1) from a first exhaust gas source (4), a first exhaust gas outlet (28, 100) for discharging exhaust gas (EG1) from the first exhaust gas source (4), and means (16, 104) for conveying exhaust gas (EG1) from a first exhaust gas source (4) from the exhaust gas inlet (26, 98) to the first exhaust gas outlet (28, 100). The marine boiler (2, 54, 56, 58, 60, 68, 74) further comprises a medium inlet (38, 94) for receiving the medium, a steam space (S) inside the container (8, 78) for containing the medium heated by means of the exhaust gases (EG1, EG2), a medium outlet (40, 96) for discharging the medium, and means (32, 92) for conveying the medium from the medium inlet (38, 94) to the medium outlet (40, 96). The marine boiler (2, 54, 56, 58, 60, 68, 74) is characterized by further comprising an electric heater (44) for heating said medium by means of electric power supplied from a power source (52) separated from said first exhaust gas source (4), said steam space (S) being arranged to contain the medium heated by means of the electric heater (44).

    提供一种用于将热量从排放气体(EG1、EG2)传递到呈锅炉水形式的介质以用于在船舶上产生蒸汽的船用锅炉(2、54、56、58、60、68、74)以及操作此类船用锅炉的方法。船用锅炉(2、54、56、58、60、68、74)包括容器(8、78)、用于接收来自第一排放气体源(4)的排放气体(EG1)的排放气体入口(26、98)、用于排出来自所述第一排放气体源(4)的排放气体(EG1)的第一排放气体出口(28、100),以及用于使来自第一排放气体源(4)的排放气体(EG1)从所述排放气体入口(26、98)传送到所述第一排放气体出口(28、100)的器件(16、104)。船用锅炉(2、54、56、58、60、68、74)还包括用于接收介质的介质入口(38、94)、用于容纳借助于排放气体(EG1、EG2)加热之后的介质的在所述容器(8、78)内侧的蒸汽空间(S)、用于排出介质的介质出口(40、96),以及用于使介质从所述介质入口(38、94)传送到所述介质出口(40、96)的器件(32、92)。船用锅炉(2、54、56、58、60、68、74)的特征在于还包括电加热器(44),其用于借助于从功率源(52)供应的电力来加热所述介质,该功率源(52)与所述第一排放气体源(4)分离,所述蒸汽空间(S)布置成容纳借助于电加热器(44)加热之后的介质。
