Embodiment approach
[0084] Hereinafter, the first embodiment of the present invention will be described. The steam generating device 1 of the present embodiment generates and discharges steam using the heat of the drainage (ie, using waste heat), and includes a first flow path 10, a second flow path 20, a heat exchanger 30, a compressor 40, a supply device 50, and a cooling device 60. Hereinafter, the steam discharged from the steam generator 1 is referred to as "produced steam".
[0085] Drain water from a heat source (not shown) such as a factory flows in the first flow path 10. In the heat exchanger 30, the heat of the fluid flowing in the first flow path 10 is transferred to the water (the heated fluid) in the second flow path 20, and the water is vaporized. This steam is compressed in the compressor 4 together with the cooling water. Then, the fluid passing through the compressor 40 is discharged from the steam generating device 1 and used in other facilities (not shown). In addition, the f...

[0179] Below, use Figure 4 The second embodiment of the present invention will be described. It should be noted that the same parts as those in the above-described embodiment are given the same reference numerals in the drawings, and their description is omitted.
[0180] Hereinafter, the description will be focused on the parts different from the above-mentioned first embodiment. in Figure 4 Among them, the portions assigned the symbols 110, 110c, 120, 120b, 160, and 161 correspond to the portions assigned the symbols 10, 10c, 20, 20b, 60, and 61 in the first embodiment, respectively.
[0181] The steam generating device 101 of this embodiment further includes a fluid supply pipe 171. Moreover, the fluid supply pipe 171 connects the downstream position (pipe 110c) of the heat exchanger 30 on the first flow path 110 and the upstream position of the heat exchanger 30 on the second flow path 120 (the upstream end of the pipe 120b). According to this structure, the fluid (fluid af...

[0192] Below, use Figure 5 The third embodiment of the present invention will be described. It should be noted that the same reference numerals are assigned to the same parts as the above-mentioned embodiment in the drawings, and the description thereof is omitted.
[0193] Hereinafter, the description will be focused on the different parts from the second embodiment. in Figure 5 Among them, the parts assigned the symbols 210, 210c, 260, and 262 correspond to the parts assigned the symbols 10, 10c, 160, and 162 in the above-mentioned embodiment, respectively.
[0194] In the steam generating device 201 of this embodiment, the cooling device 260 includes a valve 160v, a supply pipe 161, and a connecting pipe 262. The connecting pipe 262 is formed by branching from a position (pipe 10 a) upstream of the heat exchanger 30 on the first flow path 210. In addition, the connecting pipe 262 connects the pipe 10 a and the supply pipe 161. The cooling water supplied from the cooling dev...
