Embodiment Construction
[0013] The embodiments of the present invention are described in further detail below: It should be emphasized that the embodiments of the present invention are illustrative rather than limiting, so the present invention is not limited to the embodiments described in the specific implementation methods. Other implementations obtained by those skilled in the art according to the technical solution of the present invention also belong to the protection scope of the present invention.
[0014] A denitrification efficiency calculation method applied to the actual situation on site. According to the relationship between the boiler and the denitrification system on site, even if the boiler is fully loaded, due to the different types of coal burned, the amount of flue gas generated by the boiler combustion will also be large. The denitrification efficiency changes accordingly with the change of the flue gas flow rate. The present invention is how to calculate the denitrification effic...

The invention relates to a denitration efficiency calculation method applied to a field actual condition. According to the method, the denitration efficiency of different coals is separately considered and averaged according to characteristics that the boiler combustion coals are different and the corresponding flow velocity of flue gas is changed when the volume of the flue gas generated by boiler combustion is changed; comprehensive denitration efficiency of a boiler under the condition of the same load and the different combustion coals is obtained; and a formula of the calculation method is as follows: the formula is defined in the specification. By adding the flow velocity of the flue gas in detection to serve as a factor participating in calculation, the calculated comprehensive denitration efficiency is more accurate and scientific; the calculated denitration efficiency better conforms to the actual operation conditions of equipment; and more scientific data support is providedfor energy conservation and emission reduction.
Description
technical field [0001] The invention belongs to the technical field of engineering measurement, in particular to a denitrification efficiency calculation method applied to the actual situation on site. Background technique [0002] As my country's emphasis on environmental protection and related industries has gradually increased, the identification and testing methods of environmental protection equipment have been greatly improved. Among them, there are corresponding standards and specifications for the detection technology of boiler flue gas desulfurization and denitrification equipment. However, the detection standards at this stage are too simple, and few on-site factors are considered. Among them, there is still a lot of room for research on the calculation method of the denitrification efficiency of the boiler denitrification system. [0003] In the actual use of the boiler denitrification system on site, the boiler itself will have great changes in the case of using...
