CWNS series atmospheric horizontal fuel(gas) hot water boiler is a kind of horizontal internal combustion wet –back shell boiler,it is constructed by shell,internal furnace,smoke-circling box,flue tube and etc,it adopts the import burner and such fuel as light oil,heavy oil,city gas,liquid fuel and etc.
CWNS series atmospheric horizontal fuel(gas) hot water boiler is a kind of horizontal internal combustion wet –back shell boiler,it is constructed by shell,internal furnace,smoke-circling box,flue tube and etc,it adopts the import burner and such fuel as light oil,heavy oil,city gas,liquid fuel and etc.
The combustion chamber adopts the waveform internal furnace or the direct-shape internal furnace,and the wet back structure with buffwelding,thus avoding the characteristic that the back tube board is easy to be burnt out caused by the flushing of high temperature smoke gas,and ensuring the safety running of the boiler.
The smoke gas adopts the three-return design,and the smoke tube adopts the spiral spirally corrugated tube:the tubolator is inserted inside the smoke tube,thus increasing the convection heat transfer area and enhancing the heat transfer effect,the condersing heat exchange can be additionally arranged at the sensible heat and latent heat in the smoke gas,thereby improving the thermal efficiency of the boiler(95%)

Boiler performance advantage
1. Advanced: it adopts durable American and advanced energy-saving technology from Japan for long life design.
2. Energy saving: A real three-return structure, with a two-return waste heat tank set at the end to use heat, with a thermal efficiency of over 95%.
3. Durability: the boiler is made of special boiler plate, flange connection, imported accessories, uniform heating.
4. Environmental protection: nitrogen oxide emissions are lower than the national standard for a region.
Safety: strictly in accordance with the Atmospheric pressure hot water boiler Safety Technical Supervision Regulations.Unique anti-dry burning temperature control device with one more protection.
Convenience: automatic monitoring of all operations, after-sales service on call
Main Features:
Universal technology conditions for small atmospheric pressure hot water boiler and its relevant standards:therefore,its quality is fine,static pressure test and hot test are carried out on the boiler before delivering.Using the machine imported burner, pressure atomized, complete combustion, low noise, safety, efficiency and environmental protection index which conform to the national requirements.
The boiler body and expansion tank is linked together, expansion tank straight-through atmosphere, atmosphere operation, all safe hidden trouble.
The running of the boiler realizes full-auto control:the water temperature of the exit is automatically adjusted::the autoignition procedure of the boiler is started ,multiple alarming and interlocking protection devices like deaquation,overheating and flameout are prepared to ensure boiler to run effectively,safely and reliably.
Application in chemical engineer ,lipin,petrifaction,plastic pasterm,weaving ,fiber ,carbon elements,atormic energy industry,paper making printing,timber,metal,automobile,construction,cement,electric,air conditioning and other area.
