General features of WNS series hot water boiler
1. horizontal , gas & oil fired , water tube, industrial and low pressure;
2. wetback and three-backhaulstructure design;
3. With high efficiency economizer, the thermal efficiency can reach more than 90%.
4. The spring-loaded type explosion door ensures the boiler safety
5. The removable smoke boxfacilitates the maintenance
6. Internal micro positive pressure combustionreduces the low temperature corrosion.
7. Equipped with protection devicesfor overheating, overpressure, lacking water, leak detection, flameout, etc. This ensures the boiler to operate safely and efficiently.
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.
