Boiler advantages
1.Smoke and dust separator chamber
Separate smoke and dust according to inertia,reduce the original effluent concentration of soot.
2.Optimized design CAD
Choose the best furnace from dozens of options,improve economical efficiency.
3.Convex tube plate
improve tube plate flexibility, so as to reduce the heating stress of welded sew at the pipe end.
Prevent tube plate cracking, cancel bracing,simplify the structure.
4.Large size of simple circulation loop drop pipe and lower set box
Increase the flow rate of water on water cooling wall in order to prevent subcooled boiling. To prevent pipe explosion,Increase the reliability of water cycle
5.Self support
Cancel the steel frame, save steel material.
6.New pattern of furnace arch
Strengthen the combustion ,strong adaptability of coal quality,improve combustion efficiency.

Boiler design advantages
1. Adopting automatic screw feeding, with reasonable second air technology and half gasification structure
helping fuel combust completely, the thermal efficiency can reach more than 90%. Stable flame, producing
steam cautiously.
2. Primordial dust emissions density is low:The volume of the coal biomass-fired steam boiler is large and there is a dust
separation device, so the primordial dust emissions density will be controlled much lower than the standard allowed.
3. Control system: Installing microcomputer to operate with one-button, people just set the process, and it can
work automatically during the operating time. Once any abnormal situation to happen, stopping automatically
with sound-light alarm, and pointing to the failure code, so it saves time to maintain.
4. Our protected device is safe and reliable. Selecting superior pressure controller, safety valve, low water alarm,
overpressure alarm, over-temperature alarm, in order to make boilers operate safely.
5. Heating fast:There are many spiral gas tubes in the boiler and almost half of the coal fired steam boiler shell
can be heated, so the temperature can up soon.
6. It is simple to clean slag only after burning completing.
