產(chǎn)品簡介:Product Introduction:

SZS型燃氣蒸汽鍋爐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:

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，可燃氣體得到充分燃燒，提高了燃燒效率。鍋爐設(shè)有節(jié)能器，進一步提高熱效率。

設(shè)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(fā)面大，蒸汽含水率低，保證了蒸汽品質(zhì)，有效減少了用汽側(cè)負荷驟變對爐內(nèi)水位的沖擊

膜式水冷壁外安裝輕型保溫材料，采用特種復(fù)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(diào)節(jié)，各類故障連鎖保護。

配備低氮燃燒器，采用煙氣外循環(huán)（FGR）技術(shù)

鍋爐受壓本體應(yīng)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(yīng)力小，實現(xiàn)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 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.

（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?zé)煔馐紫仍跔t膛內(nèi)與水冷壁進行***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)后煙箱進入二回程對流管束，進一步散熱；流經(jīng)對流管束后，煙氣離開鍋爐本體，通過連接煙道進入尾部受熱面（節(jié)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.

The 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 sensitive

A 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 boiler
