Description

미분탄 입자의 급속 냉각용 샘플링 프로브{Sampling probe for rapid quenching of pulverized coal particle}Sampling probe for rapid quenching of pulverized coal particles

본 발명은 미분탄을 이용하는 화력발전소의 보일러 내 , 또는 전기가열 미분탄 연소반응성 실험장치(Drop Tube Furnace : DTF)와 같은 고온 반응로(섭씨 약 1300° 이상) 내에서 연소하고 있는 미분탄 입자와 반응가스를 급속 냉각하여 샘플링하기 위한 미분탄 입자의 급속 냉각용 샘플링 프로브(Probe)에 관한 것이다.The present invention relates to the combustion of pulverized coal particles and a reaction gas in a boiler of a coal-fired power plant using coal dust or in a high-temperature reactor (about 1300 ° C or more) such as an electrically heated pulverized coal combustion test apparatus (DTF). The present invention relates to a sampling probe for rapid cooling of pulverized coal particles for rapid cooling and sampling.

주지된 바와 같이 석탄화력발전소의 보울러는 200메쉬(Mesh) 이하 약 70~80% 미분된 미분탄의 연소로 인하여 보일러 내의 위치에 따라 다르긴 하지만 보통 약 1000℃~2000℃의 고온에서 운전되고 있다.As is well known, the bowler of a coal-fired power plant is usually operated at a high temperature of about 1000 ° C. to 2000 ° C., although it varies depending on the location in the boiler due to the combustion of finely divided coal from about 70% to 80%.

또한 석탄의 연소반응성 측정장치인 DTF(Drop Tube Furnace)와 같은 고온 반응로는 석탄화력보일러에서 연소환경을 모사하여 석탄의 연소반응성을 측정하는 장치로서 고온 반응로(DTF) 내 온도를 1000℃~2000℃로 유지하면서 미분탄이 반응로 내를 흐르면서 연소반응이 진행되어 진다.In addition, high-temperature reactors such as Drop Tube Furnace (DTF), which measures the combustion reactivity of coal, are used to measure the combustion reactivity of coal by simulating the combustion environment in coal fired boilers. Combustion reaction proceeds as pulverized coal flows in the reactor while maintaining at 2000 ℃.

보일러 내 혹은 고온 반응로(DTF) 내에서의 미분탄의 연소성은 탄종에 따라 다르며 입자의 탄소전환 정도, 즉 탄소전환율에 따라 연소성을 평가하게 된다. 이러한 탄소전환 정도는 보일러 내 혹은 고온반응로 내의 미분탄 입자를 샘플링(Sampling)하여 함유된 탄소의 량을 측정하여 분석한다.The combustibility of pulverized coal in a boiler or in a high temperature reactor (DTF) depends on the type of coal and the combustibility is evaluated according to the degree of carbon conversion of the particles, that is, the carbon conversion rate. This degree of carbon conversion is analyzed by measuring the amount of carbon contained by sampling the pulverized coal particles in a boiler or a high temperature reactor.

샘플링시의 미분탄 입자는 고온에서 반응이 진행중인 상태로서 샘플링하는 위치에서의 탄소전환율을 정확히 측정하려면 샘플링 프로브에서 반응이 즉시 종결되어야 한다. 문헌에 의하면 반응온도가 적어도 350℃ 이하의 온도에서 더 이상의 반응이 일어나지 않는 것으로 보고되고 있다.Pulverized coal particles at the time of sampling are in a state where the reaction is in progress at high temperature, and the reaction must be immediately terminated at the sampling probe to accurately measure the carbon conversion rate at the sampling position. The literature reports that no further reactions occur at temperatures below the reaction temperature of at least 350 ° C.

또한 미분탄 입자의 반응가스의 성분 분석시 샘플링 프로브는 등속흡인(iso-kinetic sampling)이 이루어져야 한다. 즉 유동을 교란(Perturbation) 시키지 않고 샘플링 지점에서의 정확한 샘플을 위해서는 유동의 속도와 동일한 속도로 미분탄 입자와 반응가스를 흡인시켜야 한다.In addition, when analyzing the composition of the reaction gas of the pulverized coal particles, the sampling probe should be subjected to iso-kinetic sampling. In other words, for accurate sample at the sampling point without perturbating the flow, the coal dust and the reactant gas must be sucked at the same speed as the flow rate.

이와 같이 보일러 내 또는 고온반응로(DTF) 내에서의 미분탄 입자를 샘플링하는 종래 프로브는 주로 수(水) 냉각에 의하여 미분탄 입자 및 반응가스를 샘플링하는 단순한 형태의 프로브를 채용하고 있는데, 이는 프로브 내부를 흐르는 냉각수와의 열교환을 통하여 미분탄 입자와 반응가스를 냉각시키면서 샘플링하는 것이다.As described above, the conventional probe sampling the pulverized coal particles in the boiler or the high temperature reactor (DTF) employs a simple type of probe that mainly samples the pulverized coal particles and the reactant gas by water cooling. Sampling while cooling the pulverized coal particles and the reaction gas through heat exchange with the cooling water flowing through.

종래 프로브 경우 샘플링 관로 입구부분에서 미분탄 입자가 쌓이거나 반응가스 중의 습분이 프로브 금속표면에 응결되어 미분탄 입자와 함께 엉겨 붙는 경우가 있으며, 샘플링 관로 내에서도 습분과 엉겨 붙은 미분탄 입자가 관로 내벽에 부착되기도 한다.In the case of the conventional probe, pulverized coal particles may accumulate at the inlet of the sampling pipe, or moisture in the reaction gas may condense on the probe metal surface and become entangled with the pulverized coal particles. .

또한 냉각수량이 부족한 경우 샘플된 미분탄 입자나 반응가스가 급속 냉각되 지 못하여 샘플링 도중에도 계속 반응이 지속되는 경우도 있었다.In addition, when the amount of cooling water was insufficient, the sample powdered coal particles or the reaction gas could not be rapidly cooled, and the reaction continued even during sampling.

한편 보일러 혹은 고온 반응로 내의 샘플링하는 지점에서의 등속흡인(Iso-kinetic sampling)을 위해서는 샘플링 유량을 조절하여야 하지만, 종래 샘플링 프로브는 이를 확인할 수 있는 방법을 지니고 있지 않았다.On the other hand, for iso-kinetic sampling at a sampling point in a boiler or a high temperature reactor, the sampling flow rate must be adjusted, but the conventional sampling probe does not have a method for confirming this.

이에 본 발명은 상기한 바와 같이 종래 문제점을 해결할 수 있도록 고온의 미분탄 입자와 반응가스의 급속냉각을 실현함과 동시에 등속흡인 상태를 파악할 수 있는 미분탄 입자의 급속 냉각용 샘플링 프로브를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a sampling probe for rapid cooling of pulverized coal particles, which can grasp a state of constant velocity suction while at the same time realizing rapid cooling of high-temperature pulverized coal particles and a reactive gas as described above. have.

상기와 같은 목적을 달성하기 위한 본 발명은 프로브 전면에 헬륨(He)을 분산하는 8개의 분사구를 가지고 있으며, 샘플링 관로의 선단부 일정부분을 소결 금속관으로 설치하여 헬륨이 골고루 공급되어 미분탄 입자와 반응가스를 급속 냉각할 수 있고, 또한 미분탄 입자와 반응가스의 등속흡인 여부를 확인할 수 있도록 프로브 외벽과 샘플링 관로에 유동압력 측정용 구멍을 마노메터에 연결하여 이루어짐에 따라 종래 샘플링 프로브에서 문제가 되었던 샘플링 관로의 막힘 현상을 방지하고 미분탄 입자와 반응가스의 급속냉각을 달성하면서 등속흡인 상태를 파악할 수 있는 구조를 갖추게 된다.The present invention for achieving the above object has eight injection holes for dispersing helium (He) on the front surface of the probe, helium is evenly supplied by installing a predetermined portion of the sampling tube as a sintered metal tube to the pulverized coal particles and reaction gas The sampling pipe, which was a problem in the conventional sampling probe, was formed by connecting a flow pressure measuring hole to the manometer to the probe outer wall and the sampling pipe so that it could rapidly cool and check whether the coal dust and the reaction gas had constant velocity. It is possible to prevent the clogging phenomenon and achieve the rapid cooling of the pulverized coal particles and the reaction gas while having a structure capable of identifying the constant velocity suction state.

이상 설명한 바와 같이 본 발명에 의하면, 기존의 샘플링 프로브에서 자주 발생하고 있는 샘플링 프로브 입구부분, 혹은 샘플링 관로 내에서의 막힘 현상을 해결할 수 있으며, 본 샘플링 프로브에서 채취되는 미분탄 입자와 반응가스를 급속 냉각하여 더 이상의 반응을 방지함으로서 샘플링 위치에서의 연소 상태량을 정확히 파악할 수 있다.As described above, according to the present invention, it is possible to solve the blockage phenomenon in the sampling probe inlet portion or the sampling conduit which is frequently generated in the existing sampling probe, and rapidly cool the pulverized coal particles and the reaction gas collected by the sampling probe. By preventing further reactions, the amount of combustion state at the sampling position can be accurately determined.

또한 프로브 샘플링 관로와 프로브 외벽에서의 압력을 측정하고 샘플링 시스템의 흡인 펌프에서의 흡인유량을 적당히 조정하여 등속흡인을 달성할 수 있었으며 이로부터 신뢰성 있는 미분탄 연소성 데이터의 취득이 가능하도록 되어 있다.In addition, constant velocity suction can be achieved by measuring the pressure in the probe sampling pipe and the outer wall of the probe, and by adjusting the suction flow rate in the suction pump of the sampling system, thereby obtaining reliable pulverized coal combustibility data.
