본 발명은 석탄 가스화 복합발전 시스템에 관한 것으로서, 더욱 상세하게는 석탄가스를 생성하는 가스화기를 점화시키기 위한 가스화기 점화장치에 관한 것이다.The present invention relates to a coal gasification combined cycle system, and more particularly to a gasifier ignition device for igniting a gasifier for generating coal gas.
일반적으로 석탄 가스화 복합발전 시스템은, 가스화기로부터 생성된 석탄가스를 가스정제장치와 열교환기를 거쳐 연소기로 공급하여 연소시키고, 연소된 연소가스의 팽창력을 통해 가스터빈을 작동시킴으로써 발전기를 구동하여 소정의 동력을 얻도록 되어 있다.In general, a coal gasification combined cycle system supplies coal gas generated from a gasifier to a combustor through a gas purifier and a heat exchanger to combust, and operates a gas turbine through an expansion force of the combusted combustion gas to drive a generator. It is supposed to be powered.
이와 같은 일반적인 석탄 가스화 복합발전 시스템에 있어서, 실질적으로 가스터빈을 작동시키기 위한 초기 동력발생원인 석탄가스는 그 내부에 미분탄, 질소, 산소, 증기등이 유입된 가스화기의 내부를 소정의 점화장치를 통해 가열함으로써 생성된다.In such a general coal gasification combined cycle system, coal gas, which is the initial source of power for substantially operating the gas turbine, has a predetermined ignition device through a gasifier in which pulverized coal, nitrogen, oxygen, steam, etc. are introduced. Is produced by heating through.
즉, 제1도에 도시된 바와 같이, 그 내부에 화석계 연료(예를 들면 LPG 등)(3)와 압축공기(4)가 유입된 스타트-업 버너(start-up burner)(2)를 스타트-업(start-up)시킴으로써 가스화기(1)의 내부를 가열하도록 되어 있다.That is, as shown in FIG. 1, a start-up burner 2 into which fossil fuel (for example, LPG, etc.) 3 and compressed air 4 flows is introduced. The inside of the gasifier 1 is heated by start-up.
그러나 이와 같은 종래 가스화기 점화장치에 있어서는 가스화기(1) 내부를 가열하기 위한 스타트-업 버너가 화석계연료를 사용함으로써, 별도의 보조연료비가 필요하며, 또한 연료반응시 생성되는 생성물이 물 이외에 CO2등이 생성됨으로써, 가스화기 점화를 저해하는 요인이 되었다. 또한 가스화기의 점화시 가스화기의 내부를 안정화 시키는 증기를 별도의 장치를 통해 가스화기 내로 유입시켜야 함으로써, 전체 시스템이 복잡해지는 등 많은 문제점을 내재하고 있다.However, in such a conventional gasifier ignition device, since the start-up burner for heating the inside of the gasifier 1 uses fossil fuels, a separate auxiliary fuel cost is required, and the product generated during the fuel reaction is produced in addition to water. The production of CO 2 and the like has been a factor in inhibiting gasifier ignition. In addition, when the gasifier is ignited, the steam that stabilizes the inside of the gasifier must be introduced into the gasifier through a separate device, and thus, there are many problems inherent in the overall system.
본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 수소-산소버너를 통해 가스화기 내부를 가열함으로써 연료절감을 도모할 수 있으며, 특히 별도의 증기유입장치가 불필요하여 전체 시스템의 간소화를 도모할 수 있는 가스화기 점화장치를 제공함에 그 목적이 있다.The present invention has been made to solve such a conventional problem, it is possible to reduce the fuel by heating the gasifier inside the hydrogen-oxygen burner, in particular, the need for a separate steam inlet device to simplify the overall system It is an object to provide a gasifier ignition device that can be achieved.
이와같은 목적을 달성하기 위하여 본 발명에 따른 석탄 가스화 복합발전 시스템의 가스화기 점화장치는, 그 내부에 산소, 수소, 질소, 미분탄이 유입되는 가스화기와; 수소-산소반응에 의해 발생된 화염을 통해 상기 가스화기 내부를 가열하여 석탄가스를 생성시키는 수소-산소버너; 상기 가스화기로부터 생성된 석탄가스로부터 고형입자와 황성분을 제거하는 가스정제장치와; 상기 가스정제장치로부터 정제된 석탄가스에 포함된 수소를 흡착하는 수소저장금속이 내장된 수소금속저장실과; 상기 수소금속저장실내의 수소저장금속을 가열하여 수소저장금속에 흡착된 수소를 증발시키는 열원과; 상기 수소저장금속으로부터 증발된 수소가스를 소정압력으로 상기 수소-산소버너에 공급시키는 콘트롤러;를 포함하는 것을 그 특징으로 한다.In order to achieve the above object, the gasifier ignition apparatus of the coal gasification combined cycle system according to the present invention includes a gasifier in which oxygen, hydrogen, nitrogen, pulverized coal is introduced therein; A hydrogen-oxygen burner that generates coal gas by heating the inside of the gasifier through a flame generated by a hydrogen-oxygen reaction; A gas purifier for removing solid particles and sulfur components from the coal gas generated from the gasifier; A hydrogen metal storage chamber containing a hydrogen storage metal for adsorbing hydrogen contained in the coal gas purified from the gas purification apparatus; A heat source for heating the hydrogen storage metal in the hydrogen metal storage chamber to evaporate hydrogen adsorbed on the hydrogen storage metal; And a controller for supplying the hydrogen gas evaporated from the hydrogen storage metal to the hydrogen-oxygen burner at a predetermined pressure.
본 발명의 바람직한 한 특징은, 상기 수소-산소버너의 수소-산소반응에 의해 생성되는 고온의 증기를 상기 가스화기로 공급하는 것에 있다.One preferred feature of the present invention is to supply the hot vapor generated by the hydrogen-oxygen reaction of the hydrogen-oxygen burner to the gasifier.
이와 같은 본 발명의 특징적인 구성 및 이에 따른 작용효과는 후술하는 첨부된 도면을 참조한 발명의 상세한 설명을 통해 더욱 명확해질 것이다.Such a characteristic configuration and effects of the present invention will become more apparent from the following detailed description of the invention with reference to the accompanying drawings.
제2도에서 본 발명에 따른 가스화기 점화장치는, 그 내부에 산소, 수소, 질소, 미분탄이 유입된 가스화기(10)의 내부를 수소-산소 반응에 의해 발생된 화염을 통해 가열시키는 수소-산소버너(20)를 구비한다. 이때 이 수소-산소버너(20)의 일측으로 부터는 압축공기(4)가 주입된다.In FIG. 2, the gasifier ignition apparatus according to the present invention includes a hydrogen gas for heating the inside of the gasifier 10 having oxygen, hydrogen, nitrogen, and pulverized coal introduced therein through a flame generated by a hydrogen-oxygen reaction. An oxygen burner 20 is provided. At this time, the compressed air (4) is injected from one side of the hydrogen-oxygen burner (20).
한편, 전술한 가스화기(10)의 일측에는 가스화기(10)에서 생성된 석탄가스내의 고형입자와 황성분을 제거하는 가스정제장치(30)가 마련된다. 그리고 가스정제장치(30)에 의해 정제된 석탄가스로부터 수소를 흡수하여 전술한 수소-산소버너에 공급하기 위한 수소 공급원으로써, 그 내부에 수소저장금속이 내장된 수소금속 저장실(40)과, 이 수소금속 저장실(40) 내부를 선택적으로 가열하여 수소저장금속에 흡착된 수소를 증발시키는 열원(예컨대 히이터)(50)과, 수소저장금속에서 증발된 수소를 소정의 압력으로 수소-산소버너로 공급하기 위한 콘트롤러(60)를 구비한다.On the other hand, one side of the gasifier 10 described above is provided with a gas purification device 30 for removing the solid particles and sulfur components in the coal gas generated by the gasifier 10. And a hydrogen metal storage chamber 40 having a hydrogen storage metal therein as a hydrogen supply source for absorbing hydrogen from the coal gas purified by the gas purification device 30 and supplying it to the hydrogen-oxygen burner described above. A heat source (for example, a heater) 50 for selectively heating the inside of the hydrogen metal storage chamber 40 to evaporate hydrogen adsorbed to the hydrogen storage metal, and supplying hydrogen evaporated from the hydrogen storage metal to the hydrogen-oxygen burner at a predetermined pressure. It is provided with a controller 60 for.
이때 전술한 수소-산소버너(20)에서 화염이 발생됨과 동시에 고온의 증기가 생성되는 바, 이 고온의 증기는 가스화기(10)내로 공급함이 바람직하다. 이는 별도의 장치를 통해 증기를 가스화기 내로 주입함에 있어서 발생되는 시스템의 복잡화를 간소화하기 위함이다.At this time, the flame is generated in the above-described hydrogen-oxygen burner 20 and high-temperature steam is generated. This high-temperature steam is preferably supplied into the gasifier 10. This is to simplify the system complexity that arises from injecting steam into the gasifier through a separate device.
이와같이 구성된 본 발명에 따른 석탄 가스화 복합발전 시스템의 가스화기 점화장치의 작동을 상세히 설명하면 다음과 같다.Referring to the operation of the gasifier ignition device of the coal gasification combined cycle system according to the present invention configured as described above in detail.
먼저 열원(50)을 통해 수소금속 저장실(40)내의 수소저장금속을 가열하여 수소저정금속이 포함하고 있는 수소를 증발시킨다.First, the hydrogen storage metal in the hydrogen metal storage chamber 40 is heated through the heat source 50 to evaporate hydrogen contained in the hydrogen storage metal.
이와같이 수소저장금속으로부터 증발된 수소는, 콘트롤러(60)을 통해 소정의 압력으로 수소-산소버너(20)로 공급된다.Hydrogen evaporated in this way from the hydrogen storage metal is supplied to the hydrogen-oxygen burner 20 at a predetermined pressure through the controller 60.
이와같이 수소-산소버너(20)로 공급된 수소는 수소-산소버너(20)의 일측으로부터 공급된 압축공기(4)와 수소-산소반응을 일으키게 되고 수소-산소버너(20)의 스타트-업(start-up)에 의해 화염을 발생시킴으로써 가스화기(10)내를 가열하게 된다. 이때 수소-산소버너(20)의 수소-산소반응에 의해 화염이 발생됨과 동시에 고온의 증기가 생성되는 바, 이 고온의 증기는 가스화기(10)내로 유입되어 가스화기(10)내의 미분탄, 질소, 산소등과 반응함으로써 결과적으로 석탄가스를 발생시키게 된다.In this way, the hydrogen supplied to the hydrogen-oxygen burner 20 causes a hydrogen-oxygen reaction with the compressed air 4 supplied from one side of the hydrogen-oxygen burner 20 and the start-up of the hydrogen-oxygen burner 20 ( The flame is generated by the start-up to heat the gasifier 10. At this time, the flame is generated by the hydrogen-oxygen reaction of the hydrogen-oxygen burner 20 and high-temperature steam is generated. The high-temperature steam is introduced into the gasifier 10 and the pulverized coal and nitrogen in the gasifier 10 are produced. By reacting with oxygen, the result is coal gas.
한편, 이와같이 가스화기(10)내에서 발생된 석탄가스는 가스정제장치(30)를 통과하여 고형성분과 황성분이 제거되게 되고, 정제된 석탄가스에 포함되어 있는 수소는 수소금속 저장실(40)내의 수소저장금속에 흡착되어 진다.On the other hand, the coal gas generated in the gasifier 10 is passed through the gas purification device 30 to remove the solid and sulfur components, hydrogen contained in the purified coal gas is stored in the hydrogen metal storage chamber 40 It is adsorbed by hydrogen storage metal.
따라서 석탄가스화 복합발전 시스템의 재가동시 즉, 가스화기(10)를 재차 가열할 필요가 있을 시 별도의 연료를 필요로 하지 않고 열원(50)을 통해 수소금속 저장실(40)내의 수소저장금속을 가열하는 것에 의해 수소-산소반응에 필요한 수소를 얻을 수 있다. 즉, 별도의 보조연료가 불필요하다.Therefore, when the coal gasification combined cycle system is restarted, that is, when the gasifier 10 needs to be heated again, the hydrogen storage metal in the hydrogen metal storage chamber 40 is heated through the heat source 50 without requiring a separate fuel. By doing so, hydrogen necessary for the hydrogen-oxygen reaction can be obtained. In other words, no auxiliary fuel is required.
상술한 바와 같이 본 발명에 따른 석탄 가스화 복합발전 시스템의 가스화기 점화장치에 의하면, 가스화기 자체내의 생성물인 수소를 스타트 업시 필요한 연료로 사용함으로써, 별도의 보조연료 즉, LPG 등이 불필요하여 단가절감을 도모할 수 있으며, 특히 별도의 증기를 유입시키는 장치가 없어도 수소-산소반응에 의해 생성되는 고온의 증기를 직접 가스화기내에 공급할 수 있어 이를 통한 시스템의 간소화를 도모할 수 있는 효과가 있다.As described above, according to the gasifier ignition apparatus of the coal gasification combined cycle power generation system according to the present invention, by using hydrogen, which is a product in the gasifier itself, as a fuel required for start-up, a separate auxiliary fuel, that is, LPG or the like is unnecessary, thereby reducing the unit cost. In particular, even without a device for introducing a separate steam, it is possible to supply a high-temperature steam generated by the hydrogen-oxygen reaction directly into the gasifier, thereby simplifying the system.
