The embodiment of the invention discloses a calculation method and a device for a relative performance index of a boiler unit. The calculation method for the relative performance index of the boiler unit comprises the steps of setting an optimization control parameter as oxygen quantity, acquiring boiler heat efficiency, unit heat consumption and a station service power consumption rate, calculating the boiler heat efficiency, the unit heat consumption and the station service power consumption rate to obtain relative power supply coal consumption, acquiring average concentration of NOx at an SCR inlet and a preset load setting value, calculating the average concentration of NOx at the SCR inlet and the preset load setting value to obtain SCR denitration cost, acquiring a standard coal unit price, and calculating the relative power supply coal consumption, the SCR denitration cost and the standard coal unit price to obtain relative power supply cost.
Description
technical field [0001] The invention relates to the field of relative performance indexes of boiler units, in particular to a calculation method and device for relative performance indexes of boiler units. Background technique [0002] The performance index of the boiler unit is generally obtained by off-line calculation using the performance test method. The performance index of the boiler unit obtained by this method is relatively accurate and is mainly used for the performance evaluation of the boiler unit. The power plant uses the statistical method to obtain the performance index of the boiler unit, which is used for the daily management of the power plant. However, in the boiler online combustion optimization control system, it is necessary to obtain the performance index of the boiler unit in real time, such as the online optimization control of the oxygen amount, and it is necessary to compare the economical efficiency under different oxygen amounts to find the best ...
