점선 연소되는 미분석탄로의 작동방법에 있어서, 제1레벨에서 상기로의 중심내의 가상원에 접선으로 향한로 속으로 미분된 석탄 및 1차 공기를 배출시키는 공정과, 상기 제1레벨 위의 제2레벨에서 로속으로 상기 1차 공기보다 2배 이상의 용량으로 보조공기를 배출시키는 공정과, 상기 보조공기는 상기 석탄 및 1차공기에 대한방향의 사상원에 접선방향으로 향하며, 1차 공기 및 석탄이 도입되는 다수의 제1레벨이 존재하며, 이러한 제1레벨이 보조공기가 유입되는 제2레벨에 의하여 분리되며, 보조공기 유입방향으로 회전하는 극도의 전체연소용량을 가지고, 상기 로내의 상향으로 이동하는 대향방향으로 회전하는 제1볼들을 형성하는 공정과, 더욱 큰 용량 및 속도의 공기가 이러한 방식으로 유입되기 때문에, 완전한 석탄연소가 최소로 유지되며 또한 연료 양이 이러한 방식으로 연소시키는데 과잉공기가 필요하도록 상기 석탄 및 보조공기의 훌륭한 혼합을 제공하는 공정과, 상부 로벽을 더욱 낮게 임팩팅하여 유니트의 슬러지 형성 및 오염을 감소기키는 공정을 포함하여, 증가된 믹싱 및 유니트 열 해탈율 때문에 상기 벽을 부딧히는 재가 완전히 연소되어 더욱 가루가 되기 쉽고 따라서 매연 취임을 경유하여 제거가 더욱 용이한 것을 특징으로 하는 접선 연소의 미분탄로 작동방법.A method of operating a dashed combustion unresolved coal reactor, comprising the steps of: discharging finely divided coal and primary air into a furnace tangentially to a virtual circle in the center of the furnace at a first level; Discharging auxiliary air at a level two times greater than the primary air to the furnace at the second level, wherein the auxiliary air is tangential to a sagittal source in the direction of the coal and the primary air, and the primary air and coal There are a plurality of first levels to be introduced, which are separated by a second level into which auxiliary air flows, and has an extreme total combustion capacity that rotates in the auxiliary air inflow direction, upwards into the furnace. The process of forming the first balls rotating in the opposite direction of movement, and because of the larger capacity and velocity of air introduced in this way, complete coal combustion is kept to a minimum and Providing a good mixing of the coal and auxiliary air so that the amount of material is required to burn in this way, and impacting the upper furnace wall lower to reduce sludge formation and contamination of the unit, The method of operating pulverized coal pulverizing coal characterized in that the ash adhering to the wall is completely combusted due to increased mixing and unit heat release rate, making it more powdery and thus easier to remove via soot smelting. 제1항에 있어서The method of claim 1 상기 로내에서 연소되는 석탄으로부터 열을 흡수하도록 유체가 4개의 전체 로벽에 정렬된 튜브들을 통하여 통과하는 것을 특징으로 하는 접선연소의 미분탄로 작동방법.Tangential combustion pulverized coal operating method characterized in that the fluid passes through the tubes aligned with the four whole furnace wall to absorb heat from the coal burned in the furnace. 제1항에 있어서The method of claim 1 상기 보조금공기는 상기 1차 공기 및 석탄에서보다 더큰 구경의 가상원에 접선적으로 향하는 것을 특징으로 하는 접선연소의 미분탄로 작동방법.And the subsidiary air is tangentially directed to a virtual circle having a larger diameter than in the primary air and coal. 제1항에 있어서,The method of claim 1, 과연소 공기는 상기 전체 1차 공기 및 보조공기유입 레벨위의 레벨에서 로속으로 유입되는데, 상기 과연소 공기는 상기 보조공기의 방향에 대향하는 방향으로 가상원에 접선적으로 향하는 것을 특징으로 하는 접선연소의 미분탄로 작동방법.Supercombustion air is introduced into the furnace at a level above the total primary air and auxiliary air inflow level, wherein the supercombustion air tangentially faces the imaginary circle in a direction opposite to the direction of the auxiliary air. How to operate pulverized coal furnace for combustion. 제4항에 있어서,The method of claim 4, wherein 상기 과연소 공기는 근본적으로 전체과잉 공기이며, 또한 5내지 20퍼센트의 과잉 공기인 것을 특징으로 하는 접선연소의 미분탄로 작동방법.Wherein said overburned air is essentially total excess air and is also 5 to 20 percent excess air. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
