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. |
構造與性能 Construction and Performance:
（1）內部結構：
采用上下鍋筒縱向布置，上下鍋筒間設有對流管束。下鍋筒置于鍋筒座上，與底座相連，上鍋筒通過對流管束支撐在下鍋筒上。
(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）水冷壁結構：
鍋爐爐膛為膜式水冷壁結構，膜式壁采用專門的膜式壁生產線生產，焊縫波形均勻美觀，質量好確保焊接及成形質量。全膜式壁水冷結構，氣密性好完全消除煙氣泄漏，保證了結構的穩定性，提高爐膛及煙道剛性，提高鍋爐爐壁的抗爆能力。
(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）煙氣系統：
鍋爐采用了大爐膛和對流管束二回程設計，使煙氣在爐膛內停留時間加長，可燃氣體得到充分燃燒，提高了燃燒效率。爐膛與對流管束通過水冷壁分開。高溫煙氣首先在爐膛內與水冷壁進行高效換熱，避免了直接高溫煙氣直接沖刷鍋筒，延長了鍋爐的使用壽命；煙氣在經后煙箱進入二回程對流管束，進一步散熱；流經對流管束后，煙氣離開鍋爐本體，通過連接煙道進入尾部受熱面（節能器等熱回收裝置），再進入煙囪排入大氣。
(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.
