Boiler advantages
1. CWNS series oil-fired gas hot water boiler adopts the internationally popular three-pass structure, and the large-volume design of the combustion chamber makes the combustion more complete.
2. Adopting advanced corrugated furnace structure and wet back structure, which not only increases the heat transfer area, but also satisfies the free expansion of the furnace after being heated. The boiler structure has good elasticity and thermal expansion and is safe and reliable. The smoke pipe adopts a threaded structure to strengthen the heat transfer effect.
3. The aluminum silicate fiber is used as the insulation layer, which is light in weight, good in insulation effect, and low in heat dissipation loss.
4. The hot water boiler has multiple protection functions such as over temperature, over pressure, water shortage, leak detection, flameout, etc., various safety protection devices are complete, easy to operate, safe and reliable in operation.
5. Equipped with imported burners with good self-control performance to realize fully automated operation. The boiler automation instrument and auxiliary equipment are equipped with reasonable, advanced and reliable.
6. The boiler body has low resistance, stable operation, low power consumption and low noise.
7. Quick-installation type overall structure, small size, compact structure and convenient installation.
8. There is no smoke and dust in the boiler emissions, the concentration of SO2 and NOx emissions is extremely low, and the environmental protection benefits are significant.
9. The hot water boiler has high thermal efficiency, stable output and strong load adaptability.
