증기발생수단(10)에서 발생된 증기는 증기관(9)을 통하여 보충수공급수단(20)과 연료예열수단(30)에 공급되며, 보충수공급수단(20)에는 증기관(9)이 증기보호관(21)으로 보호되어 수면상부로 공급되게 하되 공기변(25), 수면계(22) 등을 갖추는 한편 후르트볼(23)이 구비된 핀밸브(24)를 설치한다.Steam generated from the steam generating means 10 is supplied to the supplemental water supply means 20 and the fuel preheating means 30 through the steam pipe (9), the steam pipe (9) is provided to the supplemental water supply means (20) Protected by (21) to be supplied to the upper surface, but equipped with an air valve (25), water gauge (22) and the like, while installing a pin valve (24) provided with a fruit ball (23).

그리고 수동공급시 필요한 깔대기(26)를 설치 구성한다.And install the funnel (26) required for manual supply.

연료예열수단(30)은 증기관(9)이 연료저장탱크(31)하부에 형성된 연료예열통(32)내부를 코일형으로 권회된 후 배출되게 하고 상기 연료예열수단(30)을 거친 증기는 연료공급관(34)을 감싸게 형성된 증기관(33)을 경유하여 버너(40)에 공급된다.The fuel preheating means 30 causes the steam pipe 9 to be coiled inside the fuel preheating barrel 32 formed below the fuel storage tank 31 in a coil form, and the steam passed through the fuel preheating means 30 is a fuel. It is supplied to the burner 40 via the steam pipe 33 formed to surround the supply pipe 34.

버너(40)는 연료공급관(34)으로 공급된 연료가 중앙으로 배출되는 노즐(41)이 형성되고 상기 노즐(41)의 외주연에는 나선관(42)을 형성시키며 증기관(33)으로 유입된 증기가 상기 나선관(42)을 통하여 와류형태로 분사되면서 연료를 미세입자로 분사되게 구성한다.The burner 40 has a nozzle 41 for discharging fuel supplied to the fuel supply pipe 34 to the center, and forms a spiral pipe 42 on the outer circumference of the nozzle 41 and flows into the steam pipe 33. The steam is injected into the vortex form through the spiral tube 42 is configured to be injected into the fine particles of fuel.

상기 버너(40)와 노통(1)에는 각각 드레인밸브(8)(43)를 설치하여 노폐물을 배출시킬 수 있도록 한다.The burners 40 and the furnace 1 are provided with drain valves 8 and 43, respectively, to discharge the wastes.

이와 같은 구성의 본 발명에서 버너(40)가 연료를 연소시키게 되면 화염이 노통(1)을 통과하면서 증기발생수단(10)의 물이 가열되어 비등하게 되고 물이 비등된 증기는 증기관(9)을 통하여 배출된다.When the burner 40 burns fuel in the present invention as described above, the water of the steam generating means 10 is heated and boiled while the flame passes through the furnace 1, and the steam boiled in the steam tube 9 Is discharged through.

증기배출이 이루어지면 증기발생수단(10)의 수위가 감소하게 되고 수위가 감소하면 감소된 만큼 보충수공급수단(20)을 통하여 공급되게 한다.When the steam is discharged, the water level of the steam generating means 10 is reduced, and when the water level decreases, the water is supplied through the supplemental water supply means 20 as much as the water level is reduced.

증기발생수단(10)에서 발생된 증기는 증기관(9)을 통하여 보충수공급수단(20)에 공급되어 보충수의 수위를 가압하게 되고, 보충수공급수단(20)을 증기발생수단(10)보다 높게 설치하여 자연압력에 의해 보충수가 증기발생수단(10)에 공급될 수 있도록 한다.The steam generated by the steam generating means 10 is supplied to the replenishing water supply means 20 through the steam pipe 9 to pressurize the level of the replenishing water, and the replenishment water supply means 20 to the steam generating means 10 It is installed higher so that supplemental water can be supplied to the steam generating means 10 by natural pressure.

증기발생으로 인하여 증기발생수단(10)의 수위가 하강되면 후르트볼(2)이 하강되어 핀밸브(3)가 열리게 되고 이에 따라 보충수공급수단(20)으로부터 보충수를 공급받게 되고 다시 수위가 상승하면 핀밸브(3)가 닫혀 보충수 공급이 차단된다.When the water level of the steam generating means (10) is lowered due to steam generation, the fruit ball (2) is lowered to open the pin valve (3), thereby receiving the replenishing water from the replenishing water supply means (20) and the water level again. When is raised, the pin valve (3) is closed to block the replenishment water supply.

상기 과정을 반복함에 따라 증기발생수단(10)에는 자동적으로 보충수가 공급되어진다.By repeating the above process, the steam generating means 10 is automatically supplied with supplemental water.

보충수공급수단(20)에서 보충수가 빠져나간 만큼 후르트볼(23)이 하강되고 핀밸브(24)가 열려 외부로부터 용수를 보충공급받게 된다.The fruit ball 23 is lowered and the pin valve 24 is opened to receive the replenishment water from the outside as much as the replenishment water is discharged from the replenishment water supply means 20.

보충수공급수단(20)에 채워진 보충수는 증기압에 의해 압을 받게 되는 한편 예비가열되므로써 증기발생수단(10)에 공급되면 온도저하없이 빠르게 비등할 수 있도록 한다.The replenishment water filled in the replenishment water supply means 20 is pressurized by the vapor pressure while being preheated so that the replenishment water can be rapidly boiled without being lowered in temperature when supplied to the steam generating means 10.

본 발명의 보충수공급수단(20)은 보충수를 채워주는 펌프가 고장났을 경우 수작업에 의한 보충이 가능한 것으로, 수작업시는 공기변(25)을 개방한 후 깔대기(26)로 물을 채워 보충시키면 된다.The replenishment water supply means 20 of the present invention is capable of replenishment by manual operation when the pump for replenishing water is broken, and replenishes water with a funnel 26 after opening the air valve 25 during manual operation. Just do it.

증기발생수단(10)에서 발생된 증기는 연료예열수단(30)에 공급되어지며 증기관(9)을 연료저장탱크(31) 저면에 설치된 연료예열통(32)에서 코일형태로 권회되게 하므로써 연료예열통(32)에 담긴 벙커C유, 경유, 석유 등의 연료를 예열시키게 한다.The steam generated by the steam generating means 10 is supplied to the fuel preheating means 30 and the fuel preheating is made by winding the steam pipe 9 in the form of a coil in the fuel preheating tank 32 installed on the bottom of the fuel storage tank 31. Preheat the fuel such as bunker C oil, diesel oil, petroleum contained in the barrel (32).

일반적으로 증발량 5톤 보일러의 경유연료예열통(32)은 1000ℓ짜리가 많이 사용되고 있으나 5톤 보일러는 유류소비량이 최대 430ℓ로써 초당 1.2ℓ의 기름이 흐르게 되므로 결국 연료예열통(32)은 1.2ℓ를 히팅하기 위하여 1000ℓ의 대기성유량을 보온하게 된다.In general, the diesel fuel preheater 32 of the 5-ton boiler has a large amount of 1000 liters. However, the 5-ton boiler has a maximum oil consumption of 430 ℓ and 1.2 liters of oil per second. In order to heat, the atmospheric flow of 1000 liters is kept warm.

본 발명은 연료예열통(32)을 10ℓ로 사용하여 열절감 효과를 볼 수 있도록 하였고, 특히 기존 보일러는 전기히팅장치를 사용하여 예열시켰으나 본 발명에서는 자체발생한 증기를 이용하여 예열시키도록 하므로써 전기에너지를 절약할 수 있게 된다.The present invention uses the fuel preheater 32 in 10ℓ to see the heat saving effect, and in particular, the existing boiler is preheated using an electric heating device, but in the present invention by preheating by using the steam generated by itself electric energy Can save.

연료예열통(32)에서 예열된 연료는 증기가 흐르는 증기관(33)내부에 들어 있는 연료공급관(34)을 통하여 버너(40)로 공급되게 하므로써 오일의 공급과정에서도 충분한 예열이 이루어지게 된다.The fuel preheated in the fuel preheater 32 is supplied to the burner 40 through the fuel supply pipe 34 in the steam pipe 33 through which steam flows, so that sufficient preheating is performed even in the oil supply process.

연료공급관(34)으로 공급된 오일은 버너(40)의 노즐(41)로 공급되게 되고, 연료예열통(32)에서 벙커C유를 예열시킨 증기는 증기관(33)을 통하여 노즐(41)로 공급된다.The oil supplied to the fuel supply pipe 34 is supplied to the nozzle 41 of the burner 40, and the steam preheating the bunker C oil in the fuel preheater 32 is transferred to the nozzle 41 through the steam pipe 33. Supplied.

노즐(41)은 중앙으로 연료공급관(34)에 공급된 연료가 흐르게 하고 그 주위에서 증기가 3∼4개의 나선관(42)을 통하여 와류형태로 배출되게 된다.The nozzle 41 causes the fuel supplied to the fuel supply pipe 34 to flow to the center, and vapor is discharged in the vortex form through the three to four spiral pipes 42 around the nozzle 41.

따라서 노즐(41)의 선단에는 강력한 스팀이 나선관(42)을 타고 와류형태로 배출되게 되고 이에 따라 노즐(41)을 흐르는 연료는 미세입자형태의 안개상태로 분사되어진다.Therefore, at the tip of the nozzle 41, powerful steam is discharged in the vortex form on the spiral tube 42, and thus the fuel flowing through the nozzle 41 is injected in the form of mist in the form of fine particles.

노즐(41)에서 분사된 안개형태의 오일은 점화가 쉽고 연소율이 높으며, 특히 증기의 분사에 의한 수증기의 건조로 수소가 발생하며 이때 발생된 수소는 연소효율을 높이는 촉진제로서 작용하게 된다.The mist-type oil injected from the nozzle 41 is easy to ignite and has a high combustion rate. In particular, hydrogen is generated by drying steam by injection of steam, and the generated hydrogen acts as an accelerator to increase combustion efficiency.

따라서 연소효율이 증가되고, 불완전연소로 인한 공해발생요인을 감소시키며 연료분사에 따라 별도의 전동송풍장치를 필요로 하지 않아 운전비용을 절감시킬 수 있다.Therefore, the combustion efficiency is increased, the pollution factor due to incomplete combustion is reduced, and the operation cost can be reduced because a separate electric blower is not required according to the fuel injection.

본 발명은 자체발생증기를 이용하여 연소연료의 예열과 노즐에서의 연료분사를 행하게 되는 것으로, 전동유압펌프 및 송풍기와 연료히팅장치등이 불필요하고, 연소열효율을 높힐 수 있으며 설치가 간편하다.The present invention is to preheat the combustion fuel and the fuel injection in the nozzle by using the self-generated steam, electric hydraulic pump, blower and fuel heating device, etc. are unnecessary, the combustion heat efficiency can be increased and the installation is easy.

또한 버너의 구조가 간단하고 연소효율이 높아 불완전연소가 적으므로 분해 청소가 불필요한 효과가 있는 것이다.In addition, since the burner structure is simple and the combustion efficiency is high, there is little incomplete combustion, so that the decomposition cleaning is unnecessary.
