The modular design of the boiler body realizes the overall fast installation of a large capacity boiler, shortens the installation cycle, and saves installation costs.鍋爐內部采用全膜式壁水冷結構，氣密性好，減小鍋爐主機重量和外形尺寸，縮短啟動和停爐時間。The boiler adopts a full membrane wall water-cooled structure inside, which has good airtightness, reduces the weight and external dimensions of the boiler host, and shortens the start-up and shutdown time.三回程對流管束結構，合理的煙氣流程，較低背壓，實現了正壓燃燒，尾部布置可分式節能器，降低了排煙溫度，避免了本體受熱面的低溫腐蝕。The structure of the three return convection tube bundle, reasonable flue gas flow, low back pressure, and positive pressure combustion are achieved. A detachable energy-saving device is arranged at the tail to reduce the exhaust temperature and avoid low-temperature corrosion of the heating surface of the body. 核心優勢: Core advantages:燃料燃燒充分，熱效率高Fully burned fuel with high thermal efficiency大水容積設計Large water volume design優質保溫High quality insulation智能化控制High quality insulation低氮排放Low nitrogen emissions運行安全Operational safety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。鍋爐設有節能器，進一步提高熱效率。設計中采用了較大的水容積，保留了較大的水位安全范圍，使得蒸汽蒸發面大，蒸汽含水率低，保證了蒸汽品質，有效減少了用汽側負荷驟變對爐內水位的沖擊膜式水冷壁外安裝輕型保溫材料，采用特種復合硅酸鹽板覆蓋，外掛彩鋼板，保溫效果好，外觀美觀。全自動PLC控制，觸摸屏高清顯示，一鍵啟停，負荷自動調節，各類故障連鎖保護。配備低氮燃燒器，采用煙氣外循環（FGR）技術鍋爐受壓本體應力狀況良好，鍋筒等重要受壓元件不直接受高溫火焰輻射和沖刷，受壓元件伸縮自如，熱應力小，實現更高的安全裕度。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 furnaceLight 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) technologyThe 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.（4）配件 4) Accessories節能器Energy saving device壓力表Pressure gauge超壓保護裝置Overpressure protection device水位計Water level gauge布水器Water dispenser煙氣冷凝水收集排放Collection and discharge of flue gas condensate water鍋筒配件Drum accessories分體式安裝，可依現場實際情況靈活安裝。采用優化設計的翅片管換熱器，翅化比大，翅化效率高，煙氣流阻小。大口徑表盤、指針顯示、高精度壓力表；配備專用壓力表緩沖管。遠傳壓力報警、機械式壓力開關報警、彈簧全啟式安全閥三重超壓保護裝置，確保鍋爐在額定壓力以內工作。鍋爐兩側，通過平衡桶連接水位計，板式、雙色、浮筒等多類水位計可選，水位觀察直觀、檢測穩定、控制靈敏鍋爐給水入口設置專用布水器，給水經布水器后分散均勻地進入鍋爐，避免了給水時的局部溫度驟降。采用合理的煙道結構，燃氣燃燒產生的冷凝水迅速匯集，在前后煙箱排出，極大限度減小了冷凝水對鍋爐的腐蝕人孔、手孔等檢查孔設置齊全，位置合理，維護檢修方便。Split installation, flexible installation according to actual on-site conditions. The finned tube heat exchanger with optimized design has a high finning ratio, high finning efficiency, and low flue gas flow resistance.Large caliber dial, pointer display, high-precision pressure gauge; Equipped with dedicated pressure gauge buffer tubeThe triple overpressure protection device includes remote pressure alarm, mechanical pressure switch alarm, and spring fully open safety valve to ensure that the boiler operates within the rated pressure.On both sides of the boiler, a water level gauge is connected through a balance bucket. Multiple types of water level gauges, such as plate, dual color, and float, are available. The water level observation is intuitive, the detection is stable, and the control is sensitiveA dedicated water distributor is installed at the inlet of the boiler feed water, which disperses and evenly enters the boiler after passing through the distributor, avoiding local temperature drops during feed water.By adopting a reasonable flue structure, the condensed water generated by gas combustion quickly collects and is discharged from the front and rear smoke boxes, greatly reducing the corrosion of condensed water on the boilerManholes, handholes, and other inspection holes are fully installed, reasonably positioned, and easy to maintain and repair.（5）外觀 (5) Appearance立體雕塑型外觀，在傳統外觀工藝基礎上，采用加固筋的壓花鋼板立體包裝，外觀時尚，結構牢固，穩重大氣。The three-dimensional sculptural appearance adopts reinforced embossed steel plate three-dimensional packaging on the basis of traditional appearance technology, with a fashionable appearance, firm structure, and stable atmosphere.（6）系統圖: (6) System diagram:SZS系列燃油（氣）低氮蒸汽鍋爐主要技術參數:Main technical parameters of SZS series fuel (gas) low nitrogen steam boilers 項目型號SZS4SZS6SZS10SZS15SZS20SZS25SZS30SZS35SZS40SZS50projectmodel額定蒸發量t/h461015202530354050Rated evaporation capacity額定壓力MPa1.0/1.25/1.61.0/1.25/1.61.0/1.25/1.61.0/1.25/1.61.0/1.25/1.61.0/1.25/1.61.0/1.25/1.61.0/1.25/1.61.0/1.25/1.61.0/1.25/1.6Rated pressure/2.0/2.5/2.0/2.5/2.0/2.5/2.0/2.5/2.0/2.5/2.0/2.5/2.0/2.5/2.0/2.5/2.0/2.5/2.0/2.5蒸汽溫度℃184/194/204184/194/204184/194/204184/194/204184/194/204184/194/204184/194/204184/194/204184/194/204184/194/204Steam temperature/215/224/215/224/215/224/215/224/215/224/215/224/215/224/215/224/215/224/215/224鍋爐熱效率%＞94＞94＞94＞94＞94＞94＞94＞94＞94＞94Boiler thermal efficiency適應燃料輕柴油、天然氣、焦爐煤氣、城市煤氣 Light diesel, natural gas, coke oven gas, urban gasAdapt to fuel最大件外形長度Maximum external length of the componentmm60006450759085508400920010500114701147012000最大件外形寬度Maximum external width of the componentmm2400335036603550396039604400440044003250最大件外形高度Maximum external height of the componentmm3400346036803490390039004230423042303890最大件運輸重量Maximum transportation weightt25333640485257626772
