to improve the efficiency of a boiler and steam supply of the combustion air preheater

摘要

this design is the use of air preheater of boiler in power plant, a generator output signal, especially the pressure according to the operation of the switch to the replacement of the normal, pray to get the uc5f4uc190uc2e4 prevention and power generation efficiency is increased. to improve the supply efficiency of boiler combustion in the air preheater.;the idea is to use the old boiler combustion air preheater steam extraction of the fourth and the fifth part is to control the generator output 177. 262 MW, from the fifth to the steam supply pressure switch 1 (PDSH112A) (1) and the generator output is 263 ~ 350 MW, fourth steam extraction to supply the pressure switch 2 (PDSH112B) (2), through the pressure switch 2 (PDSH112B) (2) in parallel with the pressure switch 3 (AH - MR - 01), (3) is added to the match.
