ZHAO Zhi-dan1, CHEN Zhi-gang1, WANG Kai-zhu2, et al. CONTROL OF MAIN STEAM TEMPERATURE FOR SUPERCRITICAL 600 MW UNIT EQUIPED WITH DOUBLE-INLET AND DOUBLE-OUTLET COAL PULVERIZER[J]. Thermal power generation, 2010, 39(2): 91-94.DOI:
Directing against the problems existing on supercritical 600 MW units no.3 and no.4 in Qinbei Power Generation Co Ltd ever since begining of putting them into operation
such as over temperature of the main steam
and the main steam temperature can't be automatically controlled during the process of varying load of units etc.
adjustment and optimization of the main steam temperature control
the inlet temperature control for separators
and the proportioning ratio control of water and coal etc.have been carried out.After optimization
the main operation parameters
such as the main steam temperature and pressure
and the load of units etc.
can be controlled in a reasonable range under dynamic and static operation conditions
