본 발명은 절탄기가 부착된 고효율 보일러에 관한 것으로서, 보다 상세하게는 온수나 증기보일러에 폐열회수와 함께 온수열교환을 동시에 수행하는 절탄기(economizer)를 설치하므로 열효율을 극대화할 수 있음과 연료 소모와 비용을 절감할 수 있는 고효율 보일러에 관한 것이다.The present invention relates to a high-efficiency boiler with a coal firer, and more particularly, by installing an economizer for simultaneously performing hot water heat exchange with waste heat recovery in hot water or steam boilers, which can maximize thermal efficiency and fuel consumption. It relates to a high efficiency boiler that can reduce the cost.

주지하는 바와 같이 동절기나 이름 봄 또는 늦은 가을과 같이 기온이 낮은 계절에 실내공간을 쾌적하고 따뜻하게 난방시키기 위한 난방수단으로 보일러가 이용되고 있으며, 이러한 보일러는 밀폐된 용기 내의 물이나 열매체를 연소열 또는 그 밖의 열원에 의해 가열시켜 가열된 물 또는 증기와 같은 열매체가 난방라인으로 순환되면서 실내공간을 난방시키게 된다.As is well known, a boiler is used as a heating means for heating the indoor space comfortably and warmly during the low temperature season such as winter season, name spring or late autumn. Heated by a heat source outside the heating medium such as water or steam is circulated to the heating line to heat the indoor space.

한편, 온수에 의해 실내를 난방시키는 온수기름보일러의 경우에는 가열수단인 버너가 단시간 또는 일정시간 동안 밀폐된 관체의 물을 가열시켜 실내의 난방 및 급탕을 위해 기름이나 가스를 연소시키게 되는 데, 이때 사용되는 버너는 여러 종류가 사용되고 있지만 보통 사용되고 있는 버너의 경우 불완전 연소가 자주 발생하고, 연소효율이 낮은 문제점이 있다.On the other hand, in the case of a hot water oil boiler that heats the room by hot water, a burner, which is a heating means, heats the water in a closed tube for a short time or a predetermined time to burn oil or gas for heating and hot water in the room. There are many kinds of burners used, but in the case of burners which are usually used, incomplete combustion frequently occurs, and combustion efficiency is low.

일반적인 보일러는 대부분 보일러에 연소실을 형성하여 버너에서 공급되는 연소열이 연관(열교환파이프)을 통해서 배출덕트로 배출되는데, 이때 배출되는 연소열이 높은 온도를 가지고 빠져나가므로, 많은 연소열이 낭비되어 열효율이 낮은 문제점이 있다.Most boilers form a combustion chamber in the boiler, and the combustion heat supplied from the burner is discharged to the exhaust duct through the heat exchange pipe. There is a problem.

이러한 배기가스에 의해 낭비되는 연소열을 잡기 위해 종래에 사용되는 온수나 증기 등의 보일러는 절탄기(economizer)에 온수발생을 하게 되는 열교환기를 별도로 설치하게 되므로 설치 비용이 과다하게 소요되어 경제성이 저하되며, 또한 절탄기와 열교환기를 설치하기 위한 배관 등의 각종 기기를 각각 연결 설치해야 하므로 그만큼 설치공간이 많이 필요하게 되어 공간 활용도가 떨어지게 되는 문제가 있다.Boilers, such as hot water or steam, which are conventionally used to catch the heat of combustion that is wasted by these exhaust gases, are installed separately from a heat exchanger that generates hot water in an economizer, resulting in excessive installation costs and economic efficiency. In addition, since various devices, such as piping for installing an economizer and a heat exchanger, must be connected and installed, respectively, a lot of installation space is required, and space utilization is reduced.

따라서, 본 발명은 상기한 문제를 해결하기 위하여 안출한 것으로 온수열교환과 연도 폐열회수를 동시에 수행할 수 있도록 하며 연소되는 폐열을 열원으로 사용하여 온수의 온도를 높일 수 있게 되므로 설치 작업의 간단화로 작업성을 향상시킬 수 있음과 함께 설치 공간을 최소화하여 공간 활용도를 향상시킬 수 있으며, 연료의 소모는 최소화하면서 열효율을 높일 수 있어 경제성을 향상시킬 수 있도록 한 절탄기가 부착된 고효율 보일러를 제공하고자 하는 데 그 목적이 있다.Therefore, the present invention is made in order to solve the above problems to perform the hot water heat exchange and the waste heat recovery at the same time and to increase the temperature of the hot water by using the waste heat to be burned as a heat source to simplify the installation work In addition to improving the efficiency, the space utilization can be improved by minimizing the installation space, and it is possible to provide a high-efficiency boiler with an economizer that can improve the economic efficiency by minimizing fuel consumption and improving thermal efficiency. The purpose is.

상기한 목적을 달성하기 위한 본 발명은 가스챔버에 연결되어지는 연도에 절탄기(economizer)가 설치되어지되 절탄기는 상,하부관판에 연도와 연통되어지는 배기가스 흐름관이 구비되어지며, 배기가스 흐름관을 통해 유입되는 폐열을 회수하여 보일러 본체와 절탄기 본체에 연결된 환수관과 연통되어지게 되는 관체수 흐름관이 구비되어짐을 특징으로 하는 절탄기가 부착된 고효율 보일러를 제공함에 있는 것이다.In order to achieve the above object, the present invention is provided with an economizer installed in the year connected to the gas chamber, which is provided with an exhaust gas flow pipe communicating with the flue on the upper and lower pipe plates. It is to provide a high-efficiency boiler with an economizer, characterized in that the pipe water flow pipe is to be in communication with the return pipe connected to the boiler body and the carburettor body by recovering the waste heat flowing through the flow pipe.

본 발명에 따른 절탄기(6)는 온수 보일러(1)뿐만 아니라 바람직하게는 첨부된 도면 도 4에 도시된 바와 같이 증기 보일러(1a)에 적용되어질 수 있는 것이다.The blower 6 according to the present invention can be applied not only to the hot water boiler 1 but also to the steam boiler 1a as shown in FIG. 4.

이때 상기 증기 보일러(1a)에 적용되어지는 절탄기(6)의 내부 구성은 상기의 온수 보일러(1)에 사용되는 구성과 동일하게 적용되므로 이에 대한 자세한 설명은 생략한다.At this time, since the internal configuration of the coal mill 6 applied to the steam boiler 1a is applied in the same manner as the configuration used for the hot water boiler 1, a detailed description thereof will be omitted.

상기 증기 보일러(1a)의 보일러 본체(2)에는 버너(3)로부터 가열된 물의 증기를 공급하게 되는 증기공급관(21)이 설치되어지며, 증기공급관(21)은 절탄기(6)의 상부물집(62)과 연결 설치되어지되 증기공급관(21)에는 전자밸브(25)가 설치되어진다.The boiler main body 2 of the steam boiler 1a is provided with a steam supply pipe 21 for supplying steam of the water heated from the burner 3, and the steam supply pipe 21 is an upper blister of the cinder 6.

상기의 증기 보일러(1a)의 보일러 본체(2)에는 수면계(22)와 압력조절기(24) 및 압력계(23)가 설치되어진다.The water level meter 22, the pressure regulator 24, and the pressure gauge 23 are provided in the boiler main body 2 of the said steam boiler 1a.

상기와 같은 구성으로 이루어진 본 발명의 작용효과를 살펴보면 아래와 같다.Looking at the effect of the present invention made of the above configuration as follows.

상기 버너(3)에서 공급되는 기름이나 가스 등의 연료를 가열시켜 발생되는 연소열을 보일러 본체(2)내에 설치되어지는 배관 등의 기기를 거쳐 난방공급관(11)이나 증기공급관(21)을 통해 공급하게 되며, 이와 함께 버너(3)에 의해 연소되는 연료는 가스연소실(4)에서 연소되어지고, 연소된 폐열은 연도(5)를 통해 배출되어지게 되는 것이다.The combustion heat generated by heating fuel such as oil or gas supplied from the burner 3 is supplied through a heating supply pipe 11 or a steam supply pipe 21 through a device such as a pipe installed in the boiler body 2. With this, the fuel burned by the burner 3 is burned in the gas combustion chamber 4, and the burned waste heat is discharged through the flue 5.

이때 상기 연도(5)를 통해 배출되어지는 폐열의 온도가 220 ~ 250℃ 정도의 고온이기 되기 때문에 절탄기(6)의 상부물집(62)과 하부물집(62a)에 연통되어진 관체수 흐름관(65)을 통과하게 되는 관체수가 폐열의 높은 온도에 의해 예열되어져 보일러 본체(2)내로 순환되어지게 되는 것이다.At this time, because the temperature of the waste heat discharged through the flue (5) is a high temperature of 220 ~ 250 ℃ about pipe water flow pipe communicated with the upper blister 62 and the lower blister 62a (6) The pipe water passing through 65 is preheated by the high temperature of the waste heat and circulated into the boiler body 2.

이와 같이 상기 보일러 본체(2)내로 높은 온도로 예열된 물이 순환되어지게 되므로 적은 연료로도 난방효율을 높일 수 있게 되는 것이다.In this way, the water preheated to a high temperature into the boiler body 2 is circulated so that the heating efficiency can be improved even with a small amount of fuel.

그리고 상기 절탄기(6) 내부의 배기가스 흐름관(64)으로 고온의 폐열이 통과되어짐에 따라 폐열의 높은 온도가 절탄기(6)에 연결된 온수공급관(66)을 통해 절 탄기(6)내로 유입되어지는 온수의 온도를 상승시켜주면서 온수배출관(67)을 통해 배출시키게 되는 것이다.As the high temperature waste heat is passed through the exhaust gas flow pipe 64 inside the breaker 6, the high temperature of the waste heat is introduced into the breaker 6 through the hot water supply pipe 66 connected to the breaker 6. It will be discharged through the hot water discharge pipe (67) while raising the temperature of the hot water being introduced.

그리하여 상기 절탄기(6) 내에 폐열이 회수되는 배기가스 흐름관(64)을 통과하게 되는 고온의 폐열을 회수하여 관체수 흐름관(65)을 통해 보일러 본체(2)로 순환시켜 보일러 열원으로 사용하면서 온수열교환을 동시에 수행할 수 있게 되므로 연료 소모를 최소화할 수 있으며, 종래에서처럼 절탄기와 온수발생을 하는 별도의 열교환기를 따로 설치할 필요없이 절탄기(6)내에 일체로 설치하게 되어 보일러 설비기기의 구매 비용을 절감함은 물론 설치공간을 감소시켜 고효율의 경제적인 보일러를 공급할 수 있게 되는 것이다.Thus, the high temperature waste heat passing through the exhaust gas flow pipe 64 through which waste heat is recovered in the coal firer 6 is circulated to the boiler body 2 through the pipe water flow pipe 65 and used as a boiler heat source. While it is possible to perform hot water heat exchange at the same time, fuel consumption can be minimized, and the boiler is purchased as an integral part in the breaker 6 without the need to install a separate heat exchanger that generates hot water and hot water as in the prior art. In addition to reducing costs, the installation space can be reduced to provide a high-efficiency, economical boiler.

Since it is equipped with a function to perform hot water heat exchange at the same time, as in the prior art, a plurality of inlet and outlet piping can be simplified to simplify the installation work, reduce installation cost, and reduce the installation space, thereby increasing space utilization. The waste heat discarded as the flue can be efficiently recovered and used to reduce fuel consumption, thereby reducing fuel costs and maximizing heating efficiency.
