Abstract
Description
본 발명은 고체연료인 석탄을 연소하기 직전 석탄 표면에 분사하므로서, 연소시 발생되는 황산화물을 제거할 뿐 아니라, 연소효율이 향상되도록 한 석탄용 연소촉진제에 관한 것이다.The present invention relates to a combustion accelerator for coal, which not only removes sulfur oxides generated during combustion, but also improves combustion efficiency by spraying coal, which is a solid fuel, on the surface of coal just before combustion.
일반적으로 각종 액체 연료나 고체연료 등을 보일러에서 연소시키거나, 폐기물 등을 소각할 때에 발생되는 배기가스에 황산화물과 일산화탄소 등의 유해물질이 함유되어있고, 이러한 유해물질은 대기 오염의 주원인이 되었다.In general, exhaust gases generated when burning various liquid fuels, solid fuels, etc. in a boiler or incineration of wastes contain harmful substances such as sulfur oxides and carbon monoxide, and these harmful substances have become a major cause of air pollution. .
특히, 황산화물을 제거하기 위한 종래의 수단으로서, 각종 연료가 소각될 때 발생되는 배기가스에 수산화칼슘 (Ca(OH)2)를 분사하여, Ca(OH)2+ SO3= CaSO4+ H2O 의 반응식과 같이, 황산화물이 수산화칼슘과 반응되어 석고로 처리하는 방법이 통용되어 왔다.In particular, as a conventional means for removing sulfur oxides, calcium hydroxide (Ca (OH) 2 ) is injected into the exhaust gas generated when various fuels are incinerated, thereby Ca (OH) 2 + SO 3 = CaSO 4 + H 2 As in the reaction scheme of O, a method of treating sulfur oxide with calcium hydroxide and treating with gypsum has been commonly used.
그러나, 이러한 종래의 방법은 황산화물의 완전한 처리가 이루어지지 않을 뿐 아니라, 황산화물을 처리하는 과정 중에 다량의 슬러지가 생성되므로, 이를 처리하기 위한 별개의 집진 장치가 필요하여, 전체 시스템의 설치 및 관리 비용이 많이 소모되는 문제가 있었다.However, such a conventional method is not only complete treatment of sulfur oxides, but also a large amount of sludge is generated during the treatment of sulfur oxides, so a separate dust collector is required to treat the sulfur oxides. There was a problem that the management cost is high.
또한, 고체 연료인 석탄은 세계적으로 매장량이 풍부하여 공급의 안정성과 경제적 측면에서 유리한 조건을 가지고 있음에도 불구하고 유체 연료 및 기체 연료에 비하여, 그 사용이 불편함과 연소 효율의 저하로 인하여 제한적으로 사용되고 있는 실정이다.In addition, coal, which is a solid fuel, has abundant reserves around the world and has favorable conditions in terms of supply stability and economics, and thus it is limited in use due to its inconvenience in use and deterioration in combustion efficiency, compared to fluid fuel and gaseous fuel. There is a situation.
근래에는 석탄의 연소방식을 개선함으로서, 석탄이 갖고 있는 고유한 문제를 해결하기 위한 많은 노력이 있어 왔으며, 특히 석탄 매장량이 풍부한 지역에서는 에너지원으로 석탄 사용을 선호하고 있는 실정이다.In recent years, many efforts have been made to solve the inherent problems of coal by improving the combustion method of coal, and in particular, the region has a preference for using coal as an energy source in abundant coal reserves.
그러나, 석탄의 연소시 배기가스에 함유되어 있는 황은 보일러 및 각종 설비를 부식시켜 수명을 단축시킬 뿐 아니라, 대기 중에 그래로 방출되면 심각한 대기오염을 유발시키는 문제가 제기되었다.However, sulfur contained in the exhaust gas during the combustion of coal not only shortens the lifespan by corroding boilers and various equipments, but also poses a problem of serious air pollution when released into the atmosphere.
때문에, 상기 황을 제거하기 위한 탈황제의 기술이 많이 연구 개발되고 있는 실정이며, 현재까지 알려진 금속산화물 탈황제는 Zn, Fe, Cu, Ca, Mg, V, Mn, Co, Sn, Pb, Cd, Mo, W, Cr 등이며, 이러한 산화물들은 배기가스 정화에 장단점을 갖고 있다.Therefore, a lot of researches and development of the technology of the desulfurization agent for removing the sulfur, metal oxide desulfurization agents known to date Zn, Fe, Cu, Ca, Mg, V, Mn, Co, Sn, Pb, Cd, Mo , W, Cr and the like, and these oxides have advantages and disadvantages for exhaust gas purification.
실험 결과에 의하면, 석탄 배기가스 중에서 H2S 농도를 20ppmv 이하로 줄일 수 있는 1차 활성성분으로 Zn, Fe, Cu, Mn, Ce 등을 들 수 있고, 첨가제로는 Cu, Fe, Mn, Cr, Ce, Co, Mo, Ni 등이 있다.According to the experimental results, Zn, Fe, Cu, Mn, Ce, etc. may be mentioned as primary active ingredients which can reduce the H 2 S concentration in the coal exhaust gas to 20 ppmv or less, and additives include Cu, Fe, Mn, Cr , Ce, Co, Mo, Ni and the like.
현재, 개발된 탈황제 중에서 혼합아연계 탈황제와 망간계 탈황제가 있으며,특히 망간계 탈황제는 망간과 알루미나가 3 : 1의 중량비로 혼합된 화합물이 섭씨 800 도의 H2- H2S 가스 혼합물로부터 황성분을 제거할 수 있다.At present, the honhapah linked desulfurizing agent and a manganese-based desulfurizing agent in the desulfurizing agent development, particularly manganese-based desulfurizing agent is manganese and alumina is 3: weight ratio of the compound is Celsius 800 degrees H 2 mixed at a 1-remove sulfur from H 2 S gas mixture can do.
그러나, 상기 망간계 탈황제는 이를 제조하기 위하여, 분말 상태의 원료를 혼합한 후 건조, 소성 시키고, 경화 공정을 거치는 등의 제조 공정을 거쳐야되기 때문에, 제조 시간이 지연될 뿐 아니라, 이를 제조하기 위한 별개의 설비가 필요하므로, 적은 비용의 에너지원인 석탄에 비하여 탈황제의 원가가 높아 실용화되지 못하고 있는 실정이었다.However, since the manganese desulfurization agent has to go through a manufacturing process such as mixing the raw materials in a powder state, drying, calcining, and curing to prepare them, not only the production time is delayed, Since separate equipment is required, the cost of desulfurization agent is higher than that of coal, which is a low-cost energy source.
또한, 현재까지 개발된 상기 탈황제는 제조를 위한 별개의 설비가 필요하거나, 제조 과정이 복잡한 문제가 있을 뿐 아니라, 그 기능이 탈황에 제한되어 있으며, 석탄의 연소 효율을 증진시키는 기능을 수행할 수 없어 연소 효율을 상상시키기 위하여 별개의 연소 촉진제를 첨가하여야 되는 번거로움이 있었다.In addition, the desulfurization agent developed to date requires a separate facility for the production, there is a complicated problem in the manufacturing process, its function is limited to the desulfurization, and can perform a function to enhance the combustion efficiency of coal. There was no hassle of adding a separate combustion promoter to imagine the combustion efficiency.
본 발명은 상기한 문제를 해결하기 위하여 연구개발된 것으로서, 붕사와 산소수에 의하여 제조된 연소촉진제에 의하여, 석탄의 연소시 발생되는 황을 간단하고 효과적으로 제거할 수 있도록 하는데 그 기술적 과제가 있다.The present invention has been developed in order to solve the above problems, there is a technical problem to be able to remove sulfur generated during the combustion of coal simply and effectively by the combustion accelerator prepared by borax and oxygen water.
본 발명의 다른 기술적 과제는 붕사와 산소수에 함유된 산소에 의하여, 석탄의 연소가 촉진되어 적은 양의 에너지로 연소 효율이 증대되도록 하는데 있다.Another technical problem of the present invention is to promote the combustion of coal by the oxygen contained in borax and oxygen water so that the combustion efficiency is increased with a small amount of energy.
본 발명의 또 다른 기술적 과제는 석탄이 연소되기 직전에 연소 촉진제를 분사시키므로서, 전체 시스템을 경제적으로 운용할 수 있도록 하는데 있다.Another technical problem of the present invention is to inject a combustion accelerator immediately before coal is combusted, so that the entire system can be economically operated.
본 발명의 또 다른 기술적 과제는 붕사에 의하여 전체 시스템의 부식이 방지되므로 고장발생을 없애고 연장되도록 하는데 있다.Another technical problem of the present invention is to prevent corrosion and extend the entire system by borax, thereby eliminating failure and extending.
본 발명은 석탄 연소시 발생되는 황을 제거하고 연소 효율을 증대시키기 위하여, 붕사와 산소소를 1 : 10 ∼20의 중량비로 혼합 조성하고, 산소수의 용존 산소량을 80∼ 100 ppm으로 하는 것이다.In the present invention, in order to remove sulfur generated during coal combustion and increase combustion efficiency, borax and oxygen are mixed at a weight ratio of 1:10 to 20, and the dissolved oxygen amount of oxygen water is 80 to 100 ppm.
석탄이 연소될 때 발생되는 So2는 고온에서 H2O 와 결합하여 H2So4가 붕사 (NaB4O7 10H2O)와 반응되어 H2So4및 Na2So4로 전환되므로서, 황의 제거가 이루어지며, 이러한 반응식은 다음과 같다.Standing so So 2 is generated when the coal is burned is combined with H 2 O in a high temperature, H 2 So 4 is reacted with borax (NaB 4 O7 10H 2 O) converted to H 2 So 4 and Na 2 So 4, sulfur Removal takes place and this scheme is as follows.
상기와 같이 반응이 진행된 후, 산소수와 붕사에 함유되어 있는 산소가 석탄의 연소 효율을 촉진시키며, 특히 상기 산소수는 별개의 산소발생기를 이용하여 용존산소량 80 ∼ 100ppm 으로 제조하는 것이다.After the reaction proceeds as described above, oxygen contained in oxygen water and borax promotes the combustion efficiency of coal, in particular, the oxygen water is prepared in a dissolved oxygen amount of 80 to 100 ppm using a separate oxygen generator.
일반적으로 물은 상온의 대기압하에서 용존산소량이 4 ∼ 7ppm이나, 본 발명은 공지의 산소 발생기를 이용하여 80 ∼ 100ppm의 산소수를 제조하며, 이것을 이용하는 것이다.Generally, although the amount of dissolved oxygen is 4-7 ppm in water under atmospheric pressure of normal temperature, this invention produces 80-100 ppm oxygen water using a well-known oxygen generator, and uses it.
상기 붕사와 산소수의 혼합 비율은 1 : 10 ∼ 20의 중량비가 바람직하며, 붕사의 함유량이 많으면 연소효율이 저하되고 붕사의 함유량이 적으면 탈황 효과가 저하된다.The mixing ratio of the borax and oxygen water is preferably in a weight ratio of 1:10 to 20. When the content of borax is high, the combustion efficiency is lowered. When the content of borax is low, the desulfurization effect is lowered.
또한, 상기 붕사는 고유효능에 의하여 보일러나 배관설비가 부식되는 것을 방지한다.In addition, the borax to prevent corrosion of the boiler or plumbing equipment by the high efficiency.
본 발명의 실시예에 의하여 설명하면 다음과 같다.Referring to the embodiment of the present invention as follows.

상기에서 제조된 연소촉진제는 석탄이 보일러의 연소실에 투입되기 직전, 스프레이 장치에 의하여 석탄표면에 분사되며, 고온의 보일러 내부에 투입되면 석탄이 연소시 발생되는 So2가 다음과 같이 반응된다.The combustion accelerator prepared above is injected onto the surface of the coal by a spray device immediately before the coal is introduced into the combustion chamber of the boiler. When the coal is injected into the boiler at high temperature, So 2 generated during combustion of the coal is reacted as follows.
즉, So2가 Na2So4로 변환되므로서 소각된 재에 잔존하게 된다.That is, So 2 is converted into Na 2 So 4 and remains in the incinerated ash.
