鍋爐本體具有以下特點:
　　The boiler body has the following characteristics:
　　1. 該筒體由拱管板和螺紋煙管組成，將筒體由準剛體結構轉變?yōu)闇蕪椥泽w結構，消除了筒體區(qū)域的拉構件，降低了應力。采用無張力低應力拱管板，大大提高了鍋爐的安全性。
　　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,鍋筒的下部由于上升管的安排行,消除鍋底桶死水區(qū),泥渣不容易沉積,鍋筒的下部有一個防火層,使鍋筒高溫區(qū)域并不是直接由火焰輻射熱量,防止鍋爐的下部外殼膨脹。
　　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、采用換熱螺桿管，強化了換熱效果，達到了鍋爐受熱快、增壓快的特點，提高了鍋爐的熱效率;由于管道內的煙霧干擾。煙管不易積塵，起到自潔作用。
　　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. 爐內兩翼型煙道由爐內水冷管組成，既為煙道，又為對流受熱面。機身結構極為緊湊，后管板不被爐內高溫煙氣洗滌。
　　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.
　　燃燒系統(tǒng):包括鏈篦機、前拱、后拱。
　　Combustion system: including grate, front arch and rear arch.
　　爐排:鍋爐采用大鏈條爐排，剛性大，通風效果好，裝卸方便。格柵前后軸長4.55m，有效寬度1.576m。采用耐熱鑄鐵側封，側封與篦板密封間隙為8mm，側封采用冷風冷卻，有效避免燒損、材料泄漏、漏風。爐排下方分為6個獨立的空氣室，空氣根據燃燒條件進行分配。進氣方式為尾部兩側進風口。采用推拉式澆口清灰裝置，有效防止爐排漏風及爐排風室間串聯空氣。
　　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. 水冷裝置:水冷低溫熱解裝置和蒸汽阻火裝置安裝在爐口。前者有效降低了爐口溫度，抑制了燃料揮發(fā)分的快速分解，使燃料燃燒更加穩(wěn)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.爐拱:為了保證鍋爐負荷和燃料的完全燃燒，鍋爐的爐拱與燃煤鍋爐的爐拱有很大的不同。
　　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、爐墻和保溫層,傳統(tǒng)光爐墻,鍋爐爐墻保溫層與一層耐火磚,一層厚厚的硅酸鋁耐火纖維,更外層的蛭石隔熱層,前煙箱煙層硅酸鋁耐火纖維董事會嵌入到紙板,耐火纖維板用鋼絲網,扁鋼,緊固件,固定在煙盒板上,耐火混凝土的外層厚度、鍋爐的保溫性能和密封性能是可靠的保證。
　　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.
