Technical characteristics
1 The boiler drum is consisted of arched tube plate and thread smoke tube, it makes the boiler Quasi steel body into quasi-elastic body structure. It cancel brace part of the tube plate, reduce the stress .Tube plate's smoke tube change from double return into single return. It solves problem of the tube plate crack
2 It takes the thread smoke tube to enhance heat transfer, improve the heat transfer coefficient and thermal efficiency. Due to disturbance of smoke in the tube, the smoke pipe is not easy to accumulate dust ,it can clean by itself .
3 The bottom of the boiler barrel layout with bank of tubes. It will avoid the dead water region in the bottom of the boiler barrel, then sludge is hard to deposit. Boiler barrel can get good cooling, it avoid the bottom of the pot shell burnt or bulge effectively.
4 Stable operation, convenient adjustment, supply strong power.
5 The boiler can remove the dust automatically, to ensure the smoke dust to reach the ruled norm of the environment protection

Automatic control and fault protection features
Boiler steam pressure automatic regulation system: boiler steam pressure automatic regulation system control system into the state of work, to meet the necessary conditions of combustion: boiler steam pressure is higher than or equal to the set pressure limit, the control system output stop signal.Until the induced draft fan is stopped.
Water supply automatic control: when the system is working or normal, start the water pump, the water pump will work, the water level differential pressure transmitter will detect the water level signal and keep the water level of the drum stable.Ensure the quality of steam.The water level gauge shows the boiler water level.
Manual control: you can also manually control the water pump by touching the button manually on the control panel.
