から水ポンプ８により供給されていた。 Conventionally, this cooling system has consisted of independent loops, as shown in FIG. In other words, 1 is a water tank such as a pure water tank or Hotwell tank installed in the preboiler equipment 2, 3 is a head tank, 4 is a soda recovery boiler, 5 is a smelt spout, and 6 is a cooling water recovery tank. The cooled water stored in 6 is transferred to the cooling water pump 7.
The smelt spout 5 is then stored in a head tank 3, cooled by natural fall from the head tank, and then collected again into a cooling water recovery tank 6.
The cooling water lost by vaporization from the head tank 3 and the cooling water recovery tank 6 is used as make-up water in the water tank 1.
The water was supplied by a water pump 8.

た。[Problems to be solved by the invention] As mentioned above, in the conventional method, the amount of heat absorbed by the smelt spout cannot be used effectively.
Moreover, since a cooling water recovery tank and a cooling water pump are required, there are disadvantages such as increased costs.
本考案は上記の点に鑑みなされたもので、冷却

れていなかつた熱が付加されることになる。 The cooling water that has cooled the smelt spout 5 is heated by the smelt spout 5 and collected into the water tank 1. As a result, the temperature of the water supplied to the soda recovery boiler 4 rises by several degrees, and heat that has not been effectively utilized in the past is added.
