產(chǎn)品簡介:

Product Introduction:

SZS型燃?xì)庹羝仩t采用汽包縱向布置結(jié)構(gòu)，分為鍋爐本體和節(jié)能裝置兩部分。鍋爐本體模塊化設(shè)計，實現(xiàn)了大容量鍋爐的整體快速安裝，縮短了安裝周期，節(jié)省了安裝成本

The SZS type gas steam boiler adopts a longitudinal arrangement structure of the drum, which is divided into two parts: the boiler body and the energy-saving device. 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(nèi)部采用全膜式壁水冷結(jié)構(gòu)，氣密性好，減小鍋爐主機(jī)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(jié)構(gòu)，合理的煙氣流程，較低背壓，實現(xiàn)了正壓燃燒，尾部布置可分式節(jié)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(yōu)勢:       

Core advantages:

構(gòu)造與性能:  

 Construction and Performance:

（1）內(nèi)部結(jié)構(gòu)：

采用上下鍋筒縱向布置，上下鍋筒間設(shè)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(jié)構(gòu)：

鍋爐爐膛為膜式水冷壁結(jié)構(gòu)，膜式壁采用專門的膜式壁生產(chǎn)線生產(chǎn)，焊縫波形均勻美觀，質(zhì)量好確保焊接及成形質(zhì)量。全膜式壁水冷結(jié)構(gòu)，氣密性好完全消除煙氣泄漏，保證了結(jié)構(gòu)的穩(wěn)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(tǒng)：

鍋爐采用了大爐膛和對流管束二回程設(shè)計，使煙氣在爐膛內(nèi)停留時間加長，可燃?xì)怏w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?zé)煔馐紫仍跔t膛內(nèi)與水冷壁進(jìn)行高效換熱，避免了直接高溫?zé)煔庵苯記_刷鍋筒，延長了鍋爐的使用壽命；煙氣在經(jīng)后煙箱進(jìn)入二回程對流管束，進(jìn)一步散熱；流經(jīng)對流管束后，煙氣離開鍋爐本體，通過連接煙道進(jìn)入尾部受熱面（節(jié)能器等熱回收裝置），再進(jìn)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.
