For the imperfections and urgent problems to be solved in design,fabrication,installation and operation of fluidized bed boilers in recent years,this article offer the technical upodating and operational adjustment for,fluidized bed,so that the environmental quality can be improved,the service life of boilers can be extended and the economic operation of boilers can then be achieved.

The harm done to a boiler by slagging is being elucidated and the reason of its formation analyzed from the poin of view of coal category,operational practice etc;accompanied by an explanation of how slagging can be mitigated by starting work with combustion optimization and operational adjustments.

Requirements for design and operation adjustment of boiler based on the characteristics of coal from Hunan;

Almost all the problems were solved by the optimization test,operation adjustment test and the recon.

Study on the algorithm for train operation adjustment based on no-delay dispatch;

Research of theory and method for train operation adjustment on double track railway lines;

The concept of “adjacent train” was introduced to build a new model for train operation adjustment on single-track railways based on their operational characteristics.
