1. Able to do boiler maintenance and boiler water treatment.

2. Should operating controls fail, runaway firing, the boiler water may reach steam temperatures.

3. Boiler water quality test results contrast, the adjustment to increase doses.

4. The control of boiler water level is special because of its diversification characteristic.

5. As to marine boiler water treatment, all the present teaching materials only describe the basic methods of the treatment, but do not deal with the particular analysis on its principle and cause.

6. Boiler water level is the sign of the boiler water level balance, so water level control is very important.

7. Boiler water treatment - Additives to treat can provide puzzling flavor results.

8. The salt concetration of boiler water can be reduced by continuous surface drainage.

9. Should operating controls fail, permitting runaway firing, the boiler water may reach steam temperatures.

10. Firstly, a fault detection algorithm of boiler water level sensor and feedwater pump is given based on the association rules and neural networks.

11. And then advice on choosing the methods of deoxygenation of boiler water is given.

12. In this paper, aiming at unreasonable designs of a 600 MW boiler water circulating pump start-up system, feasible schemes of improvement are presented and put into effect.

13. Several economical startup ways for 300MW units, such as, using the booster pumps and steam feed water pump to feed boiler water and igniting furnace by using small flow oil guns, were introduced.

14. In order to resolve the problems of energy saving and safe operation of boiler water treatment device, applies computer supervisory control and data acquisition system on engineering design.

15. That sergeancy is speaking haltingly to say finally: " Yes, general, this brushes boiler water namely. "

16. Most of these incidents are caused due to improper boiler water level control and can be seen the boiler drum water level control device in the boiler control system importance.

17. This paper makes a discussion on the formal cause and hazard of boiler scale,() and puts forward blowing out as planned in order to keep boiler water measure up to standard.

18. The cascade control and generalized predictive control were combined, and used in boiler water height control system.

19. T he antifoaming agent can prevent the surface foaming in the boiler water, and inhibit the highly suspended matter from having carry-over effect.

20. These conclusions have provided the theory instruction and the method for the boiler water tubes low frequency turbulent low examination sensor probe head designing and the actual examination work.
