摘　　要：提出了一种简单有效的带护罩的十字形钝体煤粉稳燃器，该燃烧器与一次风管相联，由十字形钝体和护罩组成，其中十字形钝体由水平钝体和垂直钝体垂直相交而成。冷热态试验结果表明，该燃烧器具有较好的空气动力特性；既保留了钝体燃烧器的优点，又克服了其不足；能够明显使着火提前，燃烧稳定性增强。A kind of simple and effective cross form blunt body pulverized coal stabilizer with protective cover were put forward, the combustor was connected with primary air tube, and was consisted of cross form blunt body and protective cover, in which cross form blunt body was intersected of level blunt body and vertical blunt body. Results of cooling and warming test had been shown:The combustor has a good air dynamic characteristic; and was both keeping advantages of blunt body combustor and overcoming it disadvantages; obviously can make the ignition in advance, its combustion stabilization was stenghtened, adaptability to altering coals and load were uniformly raised.
