In the last cycle, the No. 3 pulverized coal fired boiler of Guangzhou Petrochemical Power Company realized 320-day long-term operation, which set the record of the longest operating period of the pulverized coal fired boiler since the transformation of ultra-low emission in 2014 and set a long-period operating record , To achieve the goal of stable ultra-low emissions.
Consolidate the safety foundation.Guangzhou Petrochemical Power Station strengthened the responsibility of safety main body and formulated the system training plan by improving the operating skills of employees and taking the goal of "operating zero violation and zero non-stop of units" as objectives, including the content to be mastered in each position, including Interpretation of the interlock function of the boiler device, the main points of system isolation, analysis of fault events of process equipment and so on. According to the system articles, fault handling articles and interlocking articles, PPT training coursewares are prepared for full training. Through regularly organizing exams and field operations So as to effectively improve employees' ability to handle actual incidents and deal with unexpected incidents, laying a solid foundation for the long-term safe and stable operation of the plant.
To carry out the operation of the inspection.The station through the 'careful operation, conscientiously inspection' competitions, prompting the team carefully monitor the plate, meticulous operation, the equipment carefully maintained.Police workers and inspectors found that many endanger the safe operation of the boiler Such as technicians, squad leader Deng Zhifeng No. 3 in the pulverized coal furnace desulfurization device inspection, through the desulfurization tower issued by the subtle abnormal noise tower air leakage, and then disassembled and found that the perimeter of nearly 20 meters of the tank One-fifth of worn-out holes have been drilled and the unplanned stoppages of the boilers and the possible collapse of desulphurization towers have been avoided due to timely processing.
Strengthen the equipment management .This station in the real inspection work at the same time, strengthen the management of equipment defects, affecting the boiler long-term operation of the shortcomings of key research, so that "small defects do not overnight, big defects, but the class," the timely replacement of coal The low temperature economizer of the powder furnace and the medium temperature air preheater of the No. 3 furnace.The station reforms the flue gas deflector of the low temperature economizer inlet.Aiming at the high power consumption of the pulverizing system of No. 3 pulverized coal furnace, Personnel conduct research topics, not only significantly reduce power consumption, but also for the device to create the conditions for long-term operation.
Continue to optimize the operation of the station continue to optimize the operation of the program, through the index benchmarking and operational analysis found that the boiler system problems, the implementation of optimization measures to improve operation, careful adjustment, such as coal, slash lime to take countermeasures to changes in the boiler Exhaust gas temperature and environmental indicators such as adjustments to make detailed requirements.Also in the process of adjustment is strictly in accordance with operating procedures to increase the frequency of boiler soot blowing, control of ammonia denitrification SCR ammonia input to ensure that the boiler to achieve stable ultra-low emissions.
