스팀 보일러(3)를 가동하면 연료의 연소 화염으로 스팀보일러의 연도와 연결된 가스 배출구에는 250℃ 이상의 열가스가 배출되고, 스팀 배출구에서는 130∼140℃의 스팀이 한증실(찜질방 및 사우나 시설)에 공급하게 되는바, 이때 스팀보일러에는 전체 열 중에 있어 65% 정도는 폐열처리를 하고 나머지 35% 정도는 스팀한증실(5)에서 활용하게 되는바, 본 발명에서는 가스 상태인 높은 온도(250℃)의 폐열이 폐열 회수관(3a)을 통해 열교환기(7) 내에 설치된 열교환로(7b)에 투입되어 통과하는 과정 직수 유입관(7e) 및 온수 공급관(2a)과 연결된 열교환실(7c) 내의 직수를 온수로 교환하고 응축수 이송관(4c) 및 응축수 유입관(4a)과 연결된 열교환관(7a)에서는 열교환실(7c) 내의 직수를 가열함과 동시 스팀보일러 미가동 시 열교환관(7b) 내에 온도차로 인하여 생기는 결로수 발생 현상을 방지하게 되는 것이다.When the steam boiler 3 is operated, heat gas of 250 ° C. or higher is discharged to the gas outlet connected to the flue boiler's flue as a combustion flame of fuel, and steam at 130 to 140 ° C. is discharged to the steam room (a steam room and a sauna facility). In this case, in the steam boiler, about 65% of the heat is treated in the waste heat treatment, and the remaining 35% is used in the steam steam chamber (5). Waste heat is introduced into the heat exchange path 7b installed in the heat exchanger 7 through the waste heat recovery pipe 3a and flows directly into the heat exchange chamber 7c connected to the direct inflow pipe 7e and the hot water supply pipe 2a. Is exchanged with hot water and the heat exchanger tube 7a connected to the condensate transfer tube 4c and the condensate inlet tube 4a heats the direct water in the heat exchange chamber 7c and at the same time the temperature difference in the heat exchanger tube 7b when the steam boiler is not running Due to It can be prevented from occurring phenomena.

It can be applied to a device that produces hot water.

상기한 바와 같이 본 발명은 스팀보일러(3)에서 생성된 고열 중에서 그 일부인 130∼140℃의 열은 스팀(steam)으로 되어 한증실(5) 등에서 사용되고, 나머지 250℃ 이상의 가스 상태의 열은 굴뚝으로 배출시키지 않고 폐열 회수관(3a)을 통해 열교환기(7) 내에서 열교환 된 온수를 생산하고 또한 한증실(5)에서 응축된 응축수는 응축수 이송관(4c)과 연결된 열교환관(7a)을 통하여 열교환실(7c) 내의 온수를 가열함과 동시 스팀보일러(3)의 미가동 시에 생기는 열교환로(7b) 내의 결로수가 발생되는 현상을 방지할 수 있게 하였기 때문에 열 에너지의 낭비를 대폭 줄일 수 있을 뿐만 아니라 열교환기(7)의 손상 방지에도 크게 기여할 수 있는 경제적인 효과가 있는 것이다.As described above, in the present invention, the heat of 130 to 140 ° C., which is a part of the high heat generated by the steam boiler 3, becomes steam and is used in the steam room 5, and the remaining heat of the gas state of 250 ° C. or more is the chimney. The hot water heat-exchanged in the heat exchanger 7 through the waste heat recovery tube 3a is produced without condensing into the condensate. By heating the hot water in the heat exchange chamber 7c and condensation water in the heat exchange passage 7b generated when the steam boiler 3 is not running at the same time, waste of thermal energy can be greatly reduced. Not only that, there is an economic effect that can greatly contribute to preventing damage of the heat exchanger (7).
