Abstract
본 발명은 노의 미세분말고체연료의 과연소 공기 제어시스템에 관한 것으로서, 연료를 연소시키기 위해 2차 공기와 함께 연료/1차 공기 혼합물을 배출하는 버너 조립체가 제공되며, 배출되는 1차 공기와 2차 공기의 양은 불완전 연소를 위해 제어되며, 완전 연소를 위해 여분의 공기를 배출하는 과연소 공기 배출구가 제공되며, 이 과연소 공기 배출구는 2개의 공기 흐름을 받는데, 이중 하나는 부피가 크고 속도가 낮으며, 다른 하나는 부피가 적지만 속도가 빠르고, 최적한 공기의 양과 속도를 얻기 위해 공기 흐름을 제어하는 댐퍼가 제공되며, 한 실시예에 따르면, 상기한 공기 흐름중 하나에 대한 공기 흐름원은 버너 조립체에 공급된 연료/1차 공기 혼합물의 1차 공기 부분이며, 그 결과 연료의 질과 이용가능한 공기의 양이 변하더라도 연료 공기 비율이 매우 정밀하게 유지될 수 있고, 이산화질소의 형성을 감소시킬 수 있는 것을 특징으로 한다.The present invention relates to a supercombustion air control system for a fine powder solid fuel of a furnace, and is provided with a burner assembly for discharging a fuel / primary air mixture together with secondary air to combust a fuel. The amount of secondary air is controlled for incomplete combustion and is provided with a supercombustion air outlet that exhausts excess air for complete combustion, which receives two air streams, one of which is bulky and velocity Low, high volume, high speed, damper for controlling the air flow to obtain an optimal amount and speed of air, and in one embodiment, an air flow for one of the air streams described above. The circle is the primary air portion of the fuel / primary air mixture supplied to the burner assembly, so that the fuel air ratio will change even if the quality of the fuel and the amount of available air change. It can be kept very precisely and can reduce the formation of nitrogen dioxide.
