环亚ag88 www.mphdfx.cn 生物质环亚ag88技术特点:
1、热风炉排下面有独立调节风室,两侧进风;采用新型曲臂螺杆调节结构,从而使调风通风截面比达到100%;调节灵活,布风均匀。设计推拉式闸板清灰装置,闸板采用耐热铸铁精加工密封结构,从而有效防止二次燃烧变形和炉排漏风?!?br /> 2、两翼烟道的设置,使烟气顺利进入前烟箱,使之前管板温度相同,避免因温度应力而产生管板裂纹。

3、锅筒内采用单回程螺纹烟管,强化了传热效果,同时螺纹烟管具有自清灰功能,避免了烟管内积灰。
4、10t/h系列热风炉前、后拱均采用了水冷壁管作支撑的整体浇注结构,形成永久拱。拱形设计采用“西安交通大学国家科技进步二等奖”最新科研成果,后拱低而长,出口段为反倾斜,前拱倾角45°与后拱相呼应,形成明显倒“α”火焰,有利于劣质煤的燃烧,煤种适应性强。
5、热风炉排侧密封结构设计先进合理,避免了侧密封卡热风炉排和热风炉排两侧布风不均匀而烧坏侧密封的缺陷。40t/h及以下热风炉采用侧密封冷加角铁筋板结构,6t/h以上热风炉采用接触式侧密封下密封结构。
6、通过将两侧集箱上的部分上升管拉向护膛,然后引入锅筒侧下方并辅以锅筒底部隔热整浇成型组成炉顶受热面,以新颖的炉膛结构成功解决了锅筒底部直接受高温火焰辐射,避免产生“鼓包”缺陷。
Technical characteristics of biomass hot blast furnace:
1, under the grate, the wind chamber is adjusted independently, and the wind is adjusted on both sides. A new type of curved arm screw is used to adjust the structure, so that the ratio of wind regulating ventilation section is 100%, and the adjustment is flexible and the air distribution is uniform. A push pull type gate cleaning device is designed. The gate plate is made of heat-resistant cast iron fine processing seal structure, thereby effectively preventing the two combustion deformation and the air leakage of the grate. 2. The installation of two flue flue gas makes the flue gas smoothly enter the front smoke box, making the temperature of the tube plate same before, avoiding the tube plate crack caused by temperature stress.
3. A single return thread cigarette tube is adopted in the boiler barrel to enhance the heat transfer effect. Meanwhile, the threaded pipe has the function of self cleaning and avoids ash accumulation in the flue pipe.
4, the front and rear arch of 10t/h series hot blast stove adopts the integral pouring structure supported by water wall tube, forming permanent arch. The arch design adopts the latest research achievements of "the two prize for national scientific and technological progress of Xi'an Jiao Tong University", the rear arch is low and long, the exit section is reverse inclined, the front arch angle is 45 degrees to the rear arch, forming a clear "alpha" flame, which is beneficial to the combustion of inferior coal, and the coal has a strong adaptability.
5. The design of the side seal structure of the grate is advanced and reasonable. It avoids the defects of the side seal card and the side of the grate on the two sides of the grate. The 40t/h and the following hot blast stove adopt the side seal cold add angle iron rib board structure, 6t/h above hot stove uses the contact side seal bottom seal structure.
6. By pulling part of the riser on both sides of the box to the chamber, and then introducing the bottom of the pot and supplemented with heat insulation at the bottom of the pot to form the heat surface of the top, the new furnace structure has successfully solved the radiation of the bottom of the pot directly by the high temperature flame to avoid the "drum" defect.
