A specific description will be given based on the embodiment shown in FIG. In addition,
In FIG. 1, the same parts as those of the related art described with reference to FIG. 2 are denoted by the same reference numerals to avoid redundancy, and detailed description is omitted. In this embodiment, a part of the condensed water 30 branches off from the conduit of the circulating water 30 that has exited the H 2 O condenser 34, and the branched condensed water 4
In the condensed water cooler 41, 0 is further cooled by the seawater 21 that has just been taken from the sea, and then injected into the CO 2 condenser 37.

One end of a pipe for extracting the non-condensable residual gas component 42 is connected to the upper part or stagnation part of the pipe 7, and the other end of the pipe is connected to a pipe of the oxygen gas 15 via an ejector 43. In this apparatus of this embodiment having the configuration, CO 2 condenser excess oxygen and carbon monoxide gas is noncondensable gas component 42 of the CO 2 condenser 37 by gas induction action of the ejector 43 using oxygen gas 15 Since it can be removed without remaining in the 37, it is possible to prevent the performance of the CO 2 condenser 37 from deteriorating due to the presence of uncondensed gas.

できる。As described above in detail, the high-pressure spray combustion apparatus according to the present invention is provided with a condensed water cooler, in which the cooled condensed water is led to a CO 2 condenser to reduce the amount of C 2.
It is possible to prevent soot from adhering to the surface of the heat transfer tube of the O 2 condenser and causing the soot to be scaled. Further, in the high-pressure spray combustion device according to the present invention, a residual gas supply path for removing uncondensed residual gas from the CO 2 condenser is provided, and the residual gas is guided to the oxygen gas supply path via the ejector. This prevents the performance of the CO 2 condenser from decreasing due to the presence of non-condensable gas. In the high-pressure spray combustion device according to the present invention, the number of operation stoppages is extremely reduced due to the above two effects, and as a result, an improvement in efficiency and a significant reduction in operation cost can be expected.

装置。1. A high-pressure combustor, a two-fluid atomizer for spraying fuel oil into the high-pressure combustor with a spray medium, and an oxidant is heated by combustion exhaust gas generated in the high-pressure combustor to generate oxygen gas. An oxygen gas generator, a mixed gas supply pipe that mixes the oxygen gas and a part of the combustion exhaust gas and supplies the mixed gas into the high-pressure combustor, and cools the combustion exhaust gas to remove water vapor in the combustion exhaust gas. An H 2 O condenser for condensing, a CO 2 condenser for further cooling the flue gas to condense carbon dioxide in the flue gas, and a part of the water condensed in the H 2 O condenser for the flue gas in the steam generator vaporize heated, in which steam generated in the steam generator and a atomizing medium supply line for supplying a spraying medium to the two-fluid sprayer, obtained in H 2 O condenser Condensed water Condensate cooler part is further cooled, condensed water pipe for supplying the condensed water that has been cooled by the condensate cooler as wash water in the heat transfer tube in the CO 2 condenser,
And a high-pressure spray combustion device having a residual gas supply path for guiding a residual gas component in the CO 2 condenser to an oxygen gas supply path from the oxygen gas generator via an ejector.
