Coal fired steam boiler design advantages:
1. The new type furnace arch strengthens the combustion, and the
coal type has strong adaptability.
2. The convex tube plate reduces the thermal stress of the pipe end
weld and eliminates the tension member to prevent the tube plate
from cracking.
3. The wing shape flue arrangement, the flue gas three return ,
reduce the temperature of the high temperature tube sheet, thereby
reducing damage to the boiler.
4. Threaded pipe, strengthen heat transfer, reduce the number of
pipes, save steel, reduce the size of the shell, reduce the thermal
stress at the end of the pipe, and prevent cracking of the pipe.

Safety System each part of Coal Fired Steam Boiler is designed
based on the safety.
1. Independently developed PLC control panel, better match our
boiler operation.more safety and easy operation.
Safety control system:
1) Control the feed pump, burner, water level sensor and pressure
controller
- Automatic Alarm when the water level is high or low, safety
interlock when the water level is over-high or over-low.
- Safety interlock for over-high pressure.
- Control the water pump feed water when the water level is low.
- Double safety valve, double water level gauge, double pressure
gauge design, backup security, safe and reliable.
- all steel materials, boiler pipe, boiler drum steel plate according
to state standard and from national standard manufacturer, ensure
the high material quality.
- Strict quality control
2.100% NDT nondestructive testing inspection for welding.
3.The boiler needs to be do the hydraulic text before leaving the
factory, and it should be under the supervision of relevant
government departments.
