난방 및 급탕용 온수보일러{HOT WATER BOILER FOR HEATING AND BATH}[0001] HOT WATER BOILER FOR HEATING AND BATH [0002]

본 발명은 난방 및 급탕용 온수보일러에 관한 것이며, 상세하게는 난방 및 급탕용 온수를 간접가열하는 온수보일러의 효율향상에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water boiler for heating and hot water supply, and more particularly, to improving the efficiency of a hot water boiler for indirectly heating hot water for heating and hot water supply.

주지하는 바와 같이 목욕탕 또는 호텔 등의 집단시설에서 난방용 또는 급탕용 등으로 사용되는 전형적인 온수보일러는 가열수조에서 가열된 온수를 직접 이용장소에서 공급하여 라디에이터, 난방코일 등의 열교환기를 순환시키거나 폐수를 버리는 것이므로 상기한 난방용의 경우에는 급수중에 포함된 규산, 유산염, 산소 등의 불순물에 의하여 발생되는 관석, 부식 등에 의하여 전열효율을 저하시키고 수명을 단축시키며, 급탕용의 경우에는 상기한 불순물에 의하여 깨끗한 온수의 사용이 곤란한 등의 결점이 있으므로 현재는 거의 온수보일러 통체의 상부에 특허문헌 1과 같이 별도의 난방용 또는/및 급탕용 열교환기를 내장한 간접가열 온수보일러로 대체한 실정이다.As is known, a typical hot water boiler used for heating or hot water in a collective facility such as a public bath or a hotel supplies hot water heated in a heating water tank directly from a use place to circulate a heat exchanger such as a radiator or a heating coil, Therefore, in the case of the above-mentioned heating, the thermal efficiency is lowered and the service life is shortened due to the presence of silicic acid, lactic acid, oxygen, etc., which are generated by impurities such as oxygen and the like, and, in the case of hot water supply, There is a drawback that it is difficult to use hot water. Therefore, at present, as in Patent Document 1, an indirect heating hot water boiler in which a separate heat exchanger for heating and / or hot water is installed is substituted for the upper part of the hot water boiler cylinder.

한편 보일러에서 연소실 등의 전열면을 가열한 연소가스는 연도를 통하여 높은 온도의 폐열이 배출되므로 그 폐열을 회수하기 위하여 연도 등에 절탄기를 설치하여 급수를 예열함으로써 연료소비량을 감소시키고 있음은 주지된 사실이다.
On the other hand, since the combustion gas heated in the combustion chamber of the boiler burns the waste heat at a high temperature through the flue, it is known that the fuel consumption is reduced by installing a burner in the flue for the recovery of the waste heat, to be.
