    • PURPOSE: A nozzle tip of a coal burner is provided to prevent cracks generated on a part of an air deflector or a side panel by forming slits in the air deflector or the side panel. CONSTITUTION: A nozzle tip(100) of a coal burner comprises inner and outer pipe bodies(130,140) and guide blades(150). The inner pipe body comprises inner panels(134) and air deflectors(132). The air deflectors are formed in the inner panels and guide the flow of fluid. First slits(132a) are formed in one side of the air deflectors. The outer pipe body is separated from the inner pipe body. The guide blades are installed inside the inner pipe body and guide the flow of coal.
    • 目的:提供煤燃烧器的喷嘴尖以通过在空气导流板或侧板中形成狭缝来防止在空气导流板或侧板的一部分上产生裂纹。 构成:煤燃烧器的喷嘴尖端(100)包括内管体和外管体(130,140)和引导叶片(150)。 内管体包括内板(134)和空气导流器(132)。 空气导流板形成在内板中并引导流体流动。 第一狭缝(132a)形成在导风板的一侧。 外管体与内管体分离。 引导叶片安装在内管体的内部,引导煤流。

    • PURPOSE: A nozzle tip of a coal burner is provided to prevent the rigidity of the nozzle tip from becoming reduced even if stress is concentrated on the corner of the nozzle tip. CONSTITUTION: A nozzle tip(100) of a coal burner comprises inner and outer pipe bodies, first and second spacers, and a cover pipe body(150). First and second inner panel members(110,120) of the inner pipe body are bent. The side corners(116a,126a) of the first and second inner panel members are welded to each other. First and second outer panel members(130,140) of the outer pipe body are bent. The side corners(134a,144a) of the first and second outer panel members are welded to each other. The first and second spacers are welded to the outer surface of the inner pipe body and form a space between the inner and outer pipe bodies. The cover pipe body is welded on the rear of the outer pipe body.
    • 目的:提供煤燃烧器的喷嘴尖以防止喷嘴尖端的刚度降低,即使应力集中在喷嘴尖端的角落。 构成:煤燃烧器的喷嘴头(100)包括内管体和外管体,第一和第二间隔件以及覆盖管体(150)。 内管体的第一和第二内板构件(110,120)弯曲。 第一和第二内板构件的侧角(116a,126a)彼此焊接。 外管体的第一和第二外板构件(130,140)弯曲。 第一和第二外板构件的侧角(134a,144a)彼此焊接。 第一和第二间隔件焊接到内管体的外表面,并且在内管体和外管体之间形成空间。 盖管体焊接在外管体的后部。

    • A pulverized coal burner is provided to easily mix and burn pulverized coals and air by simply and independently regulating the amount of the supplied pulverized coals and the amount of the air. A pulverized coal burner includes a blower(1), a air feeding pipe(2), a motor(3), a screw(4), a body(5), and a hopper(6). The blower compulsorily feeds air by using power. An air nozzle section is provided at the tie end of the air feeding pipe. The air feeding pipe is rotatably installed at an outlet of the blower to feed air. The motor rotates the air feeding pipe. The screw feeds pulverized coals as the air feeding pipe rotates. The body includes a pulverized coal nozzle section and surrounds the entire screw. The pulverized colas supplied into the interior of the body is embedded in the hopper. The hopper is communicated with an upper portion of the rear side of the body.
    • 提供粉煤燃烧器,通过简单且独立地调节供应的粉煤的量和空气量,容易地将粉煤和空气混合和燃烧。 粉煤燃烧器包括鼓风机(1),空气供给管(2),马达(3),螺杆(4),主体(5)和料斗(6)。 鼓风机强制使用动力进给空气。 空气喷嘴部分设置在供气管的连接端。 供气管可旋转地安装在鼓风机的出口进给空气。 电机旋转供气管。 当进气管旋转时,螺杆供给粉煤。 主体包括一个粉煤喷嘴部分,并围绕着整个螺丝。 供给到身体内部的粉碎的可乐被嵌入料斗中。 料斗与主体后侧的上部连通。
