Advantages of Devotion condensing steam boiler
-high efficiency: more than 103%;
-low exit flue gas temperature: as low as 60 deg C;
-low operation cost: low operation cost due to high efficiency;
-low emission: acid gas and particulars are absorbed into condensate water and discharged with exhausted flue gas;
-long life-span: long life-span tanks to application of ND steel;
Design features of Devotion condensing steam boiler
-top quality condenser: employ anti-corrosion ND steel other than carbon steel;
-unique corrugated furnace: big corrugated furnace with low Nitrogen design;
-low NOX burner: low NOX emission European burner with modulation control;
-high efficiency welding technology: guarantee welding quality of condenser and economizer;
-unique water feeding method: continuous water feeding in proportion to boiler load with frequency inverter;
-intelligent boiler controller: Siemens PLC with touch screen, fully automatic, complete protections like steam pressure, water level, temperature, etc;
