There are some difficulties to control boiler combustion for W shaped flame supercritical unit which burns inferior coal

and the regulating quality of coordinated control system and main steam temperature is also not ideal

and especially it’s hard to satisfy the requirements of rapid load regulating etc. The research of new coordination and control strategy of main steam temperature has been done to improve the coordinated load changing ability and satisfy the requirements of great and quick load changing for AGC. This paper put the primary attention to the test process and application effect of the research combining with the application situation

unit coordination and quality optimization of main steam temperature control.
