Process characteristic analysis on simultaneous desulfurization and denitriflcation for coal-fired boilers;

Selective catalytic reduction technique for flue gas denitration of coal-fired boilers;

Study on desulfrization in coal-fired boiler;

The principle and technological processes adopted in the revamping project of the desulphurization and dedusting devices of coal-burning boilers in Baosteel Special Steel Branch are introduced.

Main problem of wet flue gas desulfurization with lime in domestic mid-minor-sized coal-burning boiler are pointed out and have been verified with experiments.

The paper present situation of SO_2/NO_x combined control techniques for coal-burning boiler of power plant,analyze the principles and characteristics of these methods.

Development of automatic controller of coal boiler;

This paper introduces wet, wet integrated dry and dry fuel gas desulfuration and dedusting integrated technologies of the coal boiler, and analyzes them comprehensively.

The over-heated steam temperature of coal boiler has the characteristics of large inertia,large delaying,multi-disturbance and its dynamic performance is changed with the load,so the control for it is difficult.

In addition to introduction of common coal burning boilers and their soot and sulphur removal devices, the focus is put on the structure of water bath type deduster and the principle of soot and sulphur removal.

Analyze the principle of coal burning boiler in burning process,describe the work principle of fuzzy controller with Smith prediction,introduce the design of fuzzy controller,give the simulation study on the vapor pressure and compare it with classical PID control and PID Smith control.
