Abstract

A method and device for calculating the influence of coal quality deviation on coal consumption of a coal-fired power unit, including: measuring the actual coal consumption of the boiler, and judging whether the deviation between the coal consumption of the designed coal type and the actual coal consumption of the boiler is greater than the preset deviation value; if The deviation between the amount of coal burned by the design coal type and the actual amount of coal burned by the boiler is greater than the preset deviation value, and the change in the incomplete combustion loss of the boiler is calculated; The difference calculates the increase in power consumption rate caused by the increase in the amount of coal entering the furnace; judges whether the moisture in the coal entering the furnace exceeds the preset moisture value; if the moisture in the coal entering the furnace exceeds the preset moisture value, calculate the exhaust gas according to the deviation of the exhaust gas temperature Change in heat loss: Calculate the change in coal consumption caused by the change in coal quality based on the change in incomplete combustion loss of the boiler, the change in heat loss in exhaust smoke, and the increase in power consumption rate. The invention can quantitatively calculate the influence of the deviation of coal quality on the coal consumption of the coal-fired generating set, and accurately calculate the deviation of external conditions.

Description

technical field [0001] The invention relates to a coal consumption analysis technology of a coal-fired generating set, in particular to a calculation method and a device for the influence of coal quality deviation on the coal consumption of a coal-fired generating set. Background technique [0002] As the society's demand for electricity is getting higher and higher, how to improve the power generation efficiency of generator sets has become a problem that people pay attention to. [0003] For a certain generator set, the final energy efficiency level it can achieve depends on three factors, namely: the design and manufacturing level of the generator set; the application conditions of the generator set; management application level. The management application level of the manager to the generator set is a subjective factor of the unit operation, which can be improved through the improvement of the operation management. The design and manufacturing level of the generator se...
