BRIEF DESCRIPTION OF THE NEGATIVE PRESSURE CONTROL SYSTEM FOR BOILERS IN SECONDPHASE PROJECT OF HUANENG FUZHOU POWER PLANT[J]. Thermal power generation, 2004, (6): 51-53. DOI: 10.19666/j.rlfd.2004.06.014.
The design features of negative pressure control system in Siemens made TXP distributed control system used for 2×300 MW units imported from UK in the secondphase project of Huaneng Fuzhou Power Plant have been briefly presented
including:(1) input deviation signal of the regulator and feedforward signal of forced draft air flow; (2) treatment of input signal fluctuation for the regulator; (3) adjustment of gain for single and double units; (4) balanced circuit; (5)explosive protection in the furnace; (6) highand lowspeed changing for induced draft fan. The said control system has been put into operation and reliable performace under operating conditions
