3.Wet back smoke chamber, the whole smoke chamber is inside boiler proper, directly heating water in boiler proper, greatly increase boiler heating efficiency;
4.Three-return exhausted gas flow, ensure high temperature exhausted gas contacting with boiler tubes adequately, reduce exhausted gas temperature and increase boiler efficiency;
5. It has protective functions of over-temperature, overpressure, water shortage, leakage detection and flameout, ensuring safe and reliable operation.
Working Principle
Working principle of WNS Series horizontal single drum fire tube three pass wet back automatic industrial package oil fired hot water boiler is as follows,
The exhausted gas runs out of combustion chamber, into the wet back chamber and spirally corrugated tubes, and then through gas flue flows to the chimney.
The combustion chamber and wet back chamber, the short spirally corrugated tubes and the long spirally corrugated tubes form three-return flow, make use of the exhausted gas heating, heat the water, increase boiler efficiency.
• Three-pass exhausted gas flow diagram is as follows,
