The cooling water temperature of the generator cooling water system is 46〇C (1Q() kg/s) (design value is 42. 〇 down to the muscle (set After the ten value is 37 C), the cooling water is used to cool the lubricating oil and air of the generator. However, the cooling effect of the fan cooling system is reduced due to the aging and blockage of the fins, resulting in cooling money. It is necessary to increase the generation and 6 C separately, and it is necessary to use a cooling fan to cool the cooling water, which requires a large amount of electric power, and the relative electricity cost is increased. In addition, please refer to Fig. 4, which is a flow chart of the conventional heat recovery town furnace feeding system. It can be seen from the figure that the condensing 1 outlet is given to the Hungarian water system of the Grand Heat Exchanger.

The heart can also be used, for example, a shell and tube heat exchanger or the like. The effect of substitution = change to achieve the same effect). In this embodiment, the Glan Heat Exchange ί 2 f is connected to the rear of the condensate water pump 2 1 , and the feed water flows through the Glan Hot Father for 3 and then enters the feed water inlet 33 of the heat exchange device 3 (in addition The position of the granulated heat exchanger 2 3 can also be changed, that is, the feed water of the condensed water chestnut 2 1 can also flow through the feed water inlet 3 3 of the heat exchange device 3 for heat exchange, and then feed. The water outlet 3 4 flows to the Grand Heat exchanger 2 3 'the feed water flows to the drain heat exchanger 2 4 after the second heat exchange in the Grand Heat exchanger 2 3 . It can be seen from the above structure that the generator cooling water flows out of the two coolers 1 and 12 to become a relatively high temperature cooling water, and the cooling water flows to the cooling water inlet of the heat exchange device 3 (plate cooler). 3 1, and in the heat exchange device 3 (plate cooler) through the plate (not shown) to transfer heat to the plate and then flow through the cooling water outlet 3 2 're-flow The generator end cools the two coolers 1 1 and 1 2 . At the end of the heat recovery boiler feed water system 2, the feed water to be sent to the heat recovery boiler 2 2 first enters the feed water inlet of the heat exchange device 3 (plate cooler), and travels to the heat exchange device 3 (plate The chip cooler) flows through the plate (not shown) and transfers the heat of the cooling water of the 9 M343971 plate to the feed water, and the heat-carrying water is fed by the heat exchange device 3 (plate type) The feed water outlet of the cooler is discharged to the heat exchanger 2 3 for the second heat exchange, and then sent to the crane 2 2 for use. It can be seen from the above description that the heat transferred by the cooling water of the generator cooling system i is transferred to the feed water to be used by the recovery steel furnace 22 (the process of heat exchange) Refer to Figure 6 of Figure 1 - The working principle of the plate-type hot parent converter), in order to achieve the effect of the 埶 exchange, one of the purposes is to save the power of the cooling fan group 13 by using the generator when cooling water cooling is saved. In order to achieve the effect of energy saving, in addition, the cooling water cooling using this structure does not cause the problem of cooling fins aging and blocking the cooling efficiency. The temperature difference of cooling water cooling is closer to the theoretical data. The second is that, in addition to the above structure, the generator cooling system 1 can save the electricity required for the forced cooling fan group i 3 of the generator, and the feed of the hot f (four) furnace 22 can be used for the high temperature feeding of the mixed shouting water tank. Increase the temperature of the feed water before water to reduce the load of the condensate water cycle (see Appendix 1 for the actual test data). It is worth mentioning that 'the cooling water with heat flowing out from the two coolers 11 and 12' can be directly connected to the heat exchange device 3 (plate cooler) for heat exchange, and the control can also be selected to be turned on. The valve i 4 causes the cooling water to enter the heat exchange device 3 and the generator forced cooling fan assembly 3 to be simultaneously cooled, so that the cooling water is double cooled, and the temperature can be lowered more efficiently. The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the creation of the present invention. Therefore, any numerical changes or substitutions of equivalent elements are still within the scope of the present invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives, and it has been in compliance with the provisions of the Patent Law and has filed a patent application.
