| titleOfInvention | A Calculation Method of Boiler Flue Gas Flow Based on Zone Measurement of Denitrification Device |
| abstract | The invention relates to a boiler flue gas flow calculation method based on zoned measurement of a denitrification device, comprising the following steps: selecting measuring points for zoned measurement at the entrance and exit, and measuring the concentration values of nitrogen oxides at each measuring point; calculating the inlet and outlet Calculate the real-time ammonia escape concentration; calculate the real-time ammonia-nitrogen molar ratio; count the real-time liquid ammonia flow rate, and convert it to obtain the dry flue gas flow rate under the set oxygen content; according to the design value of the inlet flue gas humidity, Calculate the wet flue gas flow rate under the set oxygen content, and convert it to obtain the wet base flue gas flow rate under the actual inlet oxygen condition. The calculation method of the present invention is based on the denitrification device partition measurement parameters, combined with real-time liquid ammonia consumption and other parameters, through calculation to obtain the boiler flue gas flow parameters, and can use the obtained flue gas flow parameters to control and adjust the operation of the denitrification device, The adjustment performance of the optimal control of ammonia injection is improved, and the calculation process of flue gas flow is simple, with strong applicability and high accuracy. |
