» Steam Boiler

Typical Type: Down-Flow ,Fully Wet Back,Three-Pass Shell Boiler

1.Oil(Gas)Fired Steam Boiler is of the type three-pass with wet back and central back-flame in the seriesl steam output more than 1T/H,flame tubes are symmetrical on furnance axis,uniform distribution is good to improve the stress of the Tube plates,fully wet back structure combustion chanmber inundates water completely so cooling conditions is good and back tube plates will not be scoured by the high-temp smoke,so the boiler running conditions and durability can be improved.
2.The application of corrugated furnance not only increase the heating area but also lessened the damnification to buring chamber because of expansion on heating and contracting on cooling,Big volume furnance leads to completely buring and can save fuel.
3.Front flame box fit by gemel,which can bring much convenience to open.After it is opened the furnance and flame tubes can be approached to clean and maintain.What’s more,big volunm furnance design can reduce the temperature of front flame box to avoid being damaged.
4. Big steam space reduces the speed of the steam seperating from the surface of the water.The inner water separator set can insure high quality steam output.
5.Blow down automatically:The blow down valve is controled according to the concentration of boiler ,it will be opened when concentration reach to the blow down values,normally,it will be closed.(The acts above will run automatically when the boiler is stopping) so it can save labour more and lessen the waste of water and fuel,slower the form of fur-scale efficiently in the boiler,and extend the life of boiler.
6.Package construction and main auxiliary pre-assembled considerably reduce installation costs.
7.Boiler can be operated completely by just using the fingers to press keys in the intelligentize digital control system
8.Perfect protection:over-pressure switch on interlocking protection device,controllers giving alarms,burner stopped,blow down automatically with safety valves oppenning.
9.Convenient maintenance: there is a access on top of the boiler for cleaning and maintenance if it’s needed.
10.All of the boilers are tested with rated load in order to ensure the performance and reliability of burner,automatical controlling apparatus and rated security units.
