    炉膛燃烧系统结构是怎么样的?
    来源:http://www.apzhuoyou.com 发布时间:2020-04-15

      锅炉本体具有以下特点:
      The boiler body has the following characteristics:
      1. 该筒体由拱管板和螺纹烟管组成,将筒体由准刚体结构转变为准弹性体结构,消除了筒体区域的拉构件,降低了应力。采用无张力低应力拱管板,大大提高了锅炉的安全性。
      1. The tube is composed of arch tube plate and threaded smoke tube. The tube is transformed from quasi rigid structure to quasi elastic structure, which eliminates the tension components in the tube area and reduces the stress. The safety of the boiler is greatly improved by adopting non tension and low stress arch tube plate.
      2,锅筒的下部由于上升管的安排行,消除锅底桶死水区,泥渣不容易沉积,锅筒的下部有一个防火层,使锅筒高温区域并不是直接由火焰辐射热量,防止锅炉的下部外壳膨胀。
      2. Due to the arrangement of riser at the lower part of the drum, the dead water area at the bottom of the drum is eliminated, so the sludge is not easy to deposit. There is a fireproof layer at the lower part of the drum, so that the high temperature area of the drum is not directly radiated by the flame to prevent the expansion of the lower shell of the boiler.
      3、采用换热螺杆管,强化了换热效果,达到了锅炉受热快、增压快的特点,提高了锅炉的热效率;由于管道内的烟雾干扰。烟管不易积尘,起到自洁作用。
      3. The high-efficiency heat exchange screw tube is adopted to strengthen the heat exchange effect, achieve the characteristics of fast heating and fast pressurization of the boiler, and improve the thermal efficiency of the boiler; due to the interference of smoke in the pipe. The smoke pipe is not easy to accumulate dust and plays a self-cleaning role.
      4. 炉内两翼型烟道由炉内水冷管组成,既为烟道,又为对流受热面。机身结构极为紧凑,后管板不被炉内高温烟气洗涤。
      4. The two wing type flue in the furnace is composed of water cooling pipes in the furnace, which are both flue and convection heating surface. The body structure is very compact, and the rear tube plate is not washed by the high temperature flue gas in the furnace.
      燃烧系统:包括链篦机、前拱、后拱。
      Combustion system: including grate, front arch and rear arch.
      炉排:锅炉采用大链条炉排,刚性大,通风效果好,装卸方便。格栅前后轴长4.55m,有效宽度1.576m。采用耐热铸铁侧封,侧封与篦板密封间隙为8mm,侧封采用冷风冷却,有效避免烧损、材料泄漏、漏风。炉排下方分为6个独立的空气室,空气根据燃烧条件进行分配。进气方式为尾部两侧进风口。采用推拉式浇口清灰装置,有效防止炉排漏风及炉排风室间串联空气。
      Grate: large chain grate is adopted for the boiler, with large rigidity, good ventilation effect and convenient loading and unloading. The front and rear axle length of the grid is 4.55m, and the effective width is 1.576m. The heat-resistant cast iron side seal is adopted, the sealing clearance between the side seal and the grate plate is 8mm, and the side seal is cooled by cold air, so as to effectively avoid burning loss, material leakage and air leakage. There are six independent air chambers under the grate, and the air is distributed according to the combustion conditions. The air intake mode is air inlet at both sides of the tail. The utility model adopts a push-pull gate ash cleaning device to effectively prevent the air leakage of the grate and the air in series between the grate air chambers.

      2. 水冷装置:水冷低温热解装置和蒸汽阻火装置安装在炉口。前者有效降低了炉口温度,抑制了燃料挥发分的快速分解,使燃料燃烧更加稳定。
      2. Water cooling device: the water-cooled low-temperature pyrolysis device and the steam fire resistance device are installed at the furnace mouth. The former effectively reduces the furnace temperature, inhibits the rapid decomposition of fuel volatiles, and makes fuel combustion more stable.
      3.炉拱:为了保证锅炉负荷和燃料的完全燃烧,锅炉的炉拱与燃煤锅炉的炉拱有很大的不同。
      3. Furnace arch: in order to ensure the complete combustion of boiler load and fuel, the furnace arch of boiler is quite different from that of coal-fired boiler.
      4、炉墙和保温层,传统光炉墙,锅炉炉墙保温层与一层耐火砖,一层厚厚的硅酸铝耐火纤维,更外层的蛭石隔热层,前烟箱烟层硅酸铝耐火纤维董事会嵌入到纸板,耐火纤维板用钢丝网,扁钢,紧固件,固定在烟盒板上,耐火混凝土的外层厚度、锅炉的保温性能和密封性能是可靠的保证。
      4. Furnace wall and insulation layer, traditional smooth furnace wall, boiler furnace wall insulation layer and one layer of refractory brick, one layer of thick aluminum silicate refractory fiber, the outermost vermiculite insulation layer, the front smoke layer aluminum silicate refractory fiber board embedded in the cardboard, the fire-resistant fiber board is fixed on the cigarette box board with steel wire mesh, flat steel, fasteners, The thickness of the outer layer of the refractory concrete, the thermal insulation and sealing performance of the boiler are reliable guarantees.
