Boiler Features:
1.Monitoring of water level: Equipped with water level electronic detector to control the water level.
2.Setting time: The users can set the starting and stopping time as their demand.
3.Electric leakage protection: When the elements of boiler have a electric leakage, the control system will cut off power automatically.
4.Water shorage protection: When the boiler is lack of water, the system will turn off burner and raise alarm.
5.Over pressure protection:When the pressure of boiler is over your setting point, burner will stop working and raise alarm.
6.Power abnormal protection:When the power ia abnormal, the boiler will stop working immediately.
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%)
