On the morning of October 26, Yang Lei, a workshop technician in the power station of Daqing Petrochemical Refinery, routinely inspected the soot data of the last group of oil-fired boilers, and the relevant control parameters were all better than the national standards for the discharge of air pollutants from thermal power plants. Desulfurization and denitrification projects successfully passed the system calibration, the device system is stable.
Daqing Petrochemical Refinery has 3 oil-fired boilers, the output of steam for winter operation of the device used to ensure that the emission of oil-fired boilers to meet the new requirements of national environmental protection, last March, Daqing Petrochemical boiler on the desulfurization and denitrification transformation. Daqing Petrochemical strictly implement the calibration program of flue gas purification system of oil-fired boilers and actively adjust the production and calibration work.
The performance of boiler body and desulfurization and denitrification system are the key points of calibration. Daqing Petrochemical compares the 15 key indicators related to it; the staff of the post gradually find out the device by adjusting the mode of ammonia injection, the oxygen content in the furnace and the fuel ratio, etc. Optimized operation mode.After debugging and optimization, sulfur dioxide and dust emissions from oil-fired boilers dropped to 15 mg per standard cubic meter and 6.5 mg per standard cubic meter, all operating parameters were better than national standards.
