1.CWNS型系列常壓燃氣、燃油熱水鍋爐是臥式內燃濕背式鍋殼鍋爐。其主要結構由鍋殼、爐膽、火箱、一回程煙管、二回程煙管、前后煙箱等組成。適用液化石油氣、城市煤氣、天然氣等氣體，輕油、重油等液體燃料。

2.燃燒室采用了波形爐膽、回燃室，濕背式結構，避免了后管板受高溫煙氣沖刷易燒壞的特點，確保鍋爐安全運行。

3.煙氣三回程設計，煙管采用螺紋煙管，增加了對流傳熱面積和增強了傳熱效果。尾部煙道可增設冷凝換熱器，降低排煙溫度吸收煙氣中的顯熱和潛熱，從而提高鍋爐的熱效率(達96%)

4.鍋爐主體嚴格按照JB/T7985-2002《小型和常壓熱水鍋爐通用技術條件》及其相關標準生產制作、檢驗，品質精良。出廠前作靜態壓力試驗和熱態試驗。

5.鍋爐運行實現全自動控制，對出口水溫自動調節，鍋爐自動點火程序啟動，配有缺水過熱、熄火等多種報警連鎖保護裝置，確保鍋爐高效、安全、可靠運行。

6.結構緊湊，外形美觀，整體快裝出廠，運輸安裝方便。

7.廣泛應用于賓館、住宅、別墅、寫字樓、休閑娛樂場所的采暖和省生活熱水的供應。

1. Model CWNS series atmospheric horizontal fuel(gas) hor waterboiler is a kind of horizontal internal combustion wet-back shell boilerIt is constructed by shell, internal furnace. smoke-cirling box, fluetube and etc. It adopts the import burner and such fuel as light oilheavy oil, city gas, natural gas, liquid fuel and etc.

2. The combustion chamber adopts the waveform internalfurnace or the direct-shape internal furnace, and the wet backstructure with butt-Welding, thus avoiding the characteristic that theback tube board is easy to be burnt out caused by the flushing of hightemperature smoke gas, and ensuring the safety running of the boiler.

3. The smoke gas adopts the three -return design, and the smoketube adopts the spiral spirally corrugated tube; thee turbolator isinserted inside the smoke tube, thus increasing the convection heattransfer area and enhancing the heat transfer effect. The condensingheat exchanger can be additionally arranged at the tail flue to reducethe exhuast smoke ternperature and absorb the sensible heat andlatent heat in the smoke gas, thereby improving the thermal efficiencyof the boiler(96%)

4. The boiler body is manufactured and inspected strictly accordingto JB/T7985-2002 Universal Technology Conditions for SmallStmosperic Pressure Hot Water Boilers and its relevant standards,therefore, its quality is fine. Static pressure test and hot test arecarried out on the boilbr before delivering.

5. The running of the boiler relizes full-auto control the watertemperature of the exit is automatically adjusted; the autoignitionprocedure of the boiler is started. Multiple alarming and interlockingprotection devices like deaquation, overheating and flameout areprepared to ensure the boiler to run effectively, safely and re; ably.

6. The boiler has compact structure and beautiful appearance, Isentirely and quickly assembled and delivered, and is convenient to betransported and mounted.

7.The structure is compact, theappearance is beautiful, thecomplete machine is quickly factory-assembled and its transportinginstallation is convenient.
