By investigation on the start/stop process of supercritical 600MW units
time consumption during the start/stop of 600MW level units was summarized.Taking a supercritical 600MW unit configured by Dongfang Boiler Group and Harbin Turbine Company as the example
the coal consumption
oil consumption
steam consumption and electric consumption during each start/stop process were evaluated and converted to the energy consumption and auxiliary power consumption rate.Thus
the energy consumption during the unit start/stop can be judged quantitively.The results showed that
the order of the influence quantity of the unit start/stop process on the coal consumption was small
and a more accurate estimation will not affect the results substantially.Therefore
this evaluated result was suitable for unit with various capacities.
