The design of a large furnace and convection tube bundle with two return paths prolongs the residence time of flue gas in the furnace, allowing for sufficient combustion of combustible gases and improving combustion efficiency. The boiler is equipped with an energy-saving device to further improve thermal efficiency. | A larger water volume was adopted in the design, retaining a larger water level safety range, resulting in a larger steam evaporation surface and lower steam moisture content, ensuring steam quality and effectively reducing the impact of sudden changes in steam load on the water level in the furnace | Light insulation material is installed outside the membrane water-cooled wall, covered with special composite silicate board, and coated with color steel plate. The insulation effect is good and the appearance is beautiful. | Fully automatic PLC control, high-definition touch screen display, one click start stop, automatic load adjustment, and various types of fault chain protection. | Equipped with low nitrogen burners and utilizing flue gas external circulation (FGR) technology | The stress condition of the pressurized body of the boiler is good, and important pressure components such as the drum are not directly affected by high-temperature flame radiation and erosion. The pressure components can stretch and contract freely, with low thermal stress, achieving higher safety margins. |
构造与性能 Construction and Performance:
（1）内部结构：
采用上下锅筒纵向布置，上下锅筒间设有对流管束。下锅筒置于锅筒座上，与底座相连，上锅筒通过对流管束支撑在下锅筒上。
(1) Internal structure：
Adopting a longitudinal arrangement of upper and lower drums, there is a convection tube bundle between the upper and lower drums. The lower drum is placed on the drum seat and connected to the base. The upper drum is supported on the lower drum through a convection tube bundle.
（2）水冷壁结构：
锅炉炉膛为膜式水冷壁结构，膜式壁采用专门的膜式壁生产线生产，焊缝波形均匀美观，质量好确保焊接及成形质量。全膜式壁水冷结构，气密性好完全消除烟气泄漏，保证了结构的稳定性，提高炉膛及烟道刚性，提高锅炉炉壁的抗爆能力。
(2) Water cooled wall structure：
The boiler furnace adopts a membrane water-cooled wall structure, and the membrane wall is produced by a specialized membrane wall production line. The weld waveform is uniform and beautiful, and the quality is good to ensure the welding and forming quality. The full membrane wall water-cooled structure has good airtightness and completely eliminates smoke leakage, ensuring the stability of the structure, improving the rigidity of the furnace and flue, and enhancing the blast resistance of the boiler wall.
（3）烟气系统：
锅炉采用了大炉膛和对流管束二回程设计，使烟气在炉膛内停留时间加长，可燃气体得到充分燃烧，提高了燃烧效率。炉膛与对流管束通过水冷壁分开。高温烟气首先在炉膛内与水冷壁进行高效换热，避免了直接高温烟气直接冲刷锅筒，延长了锅炉的使用寿命；烟气在经后烟箱进入二回程对流管束，进一步散热；流经对流管束后，烟气离开锅炉本体，通过连接烟道进入尾部受热面（节能器等热回收装置），再进入烟囱排入大气。
(3) Smoke system：
The boiler adopts a large furnace and convection tube bundle two return design, which prolongs the residence time of flue gas in the furnace, fully combusts combustible gases, and improves combustion efficiency. The furnace and convection tube bundle are separated by a water-cooled wall. High temperature flue gas first efficiently exchanges heat with the water-cooled wall in the furnace, avoiding direct flushing of the boiler drum by high temperature flue gas and prolonging the service life of the boiler; The smoke enters the secondary convection tube bundle through the rear smoke box, further dissipating heat; After passing through the convection tube bundle, the flue gas leaves the boiler body and enters the tail heating surface (such as the energy-saving device) through the connecting flue, and then enters the chimney to be discharged into the atmosphere.
