摘要
Abstract
In order to get the optimal parameters of units which adopted different cooling characteristics in different operating points and determine the operating ways of constant pressure-sliding pressure-constant pressure, unit's coal consumption was calculated and standard coal consumption and coal consumption curve were fitted by using Matlab. Then the units' coal consumption curves and the differential curves could be reached under the condition of equal slight addition. The results showed that water-cooled units, which slight incremental coal consumption rate was low, raised the load firstly, then air-cooled units, which slight incremental coal consumption rate was high, raised the load lately; the unit adopted operating way of constant pressure when its load was higher than 80％ or less than 40％ rated load and it adopted operating way of sliding pressure when its load was between 40％ and 80％ rated load.关键词
