**Successful Ignition of Boiler in Yulin Energy Project Author/Source: Shaanxi Petrochemical News Network Date: 2020-07-27 Clicks: 140 At 0:00 on July 25, Boiler No. 6 of the power unit in Yulin’s circular economy coal comprehensive utilization project, operated by **Energy Group, was successfully ignited for the first time. This marks the successful achievement of a key milestone in this project, laying a solid foundation for the subsequent pipeline purging and commissioning of the chemical processing units. The power generation capacity includes 2 high-temperature and high-pressure coal-fired boilers with a capacity of 480 t/h each, along with 1 100 MW air-cooled extraction-type generator set. High-efficiency dust removal, coal handling and storage, as well as desulfurization and denitrification systems are also installed to ensure compliance with ultra-low emission standards. For this boiler startup, pulverized coal was used as the initial fuel, and plasma ignition was employed. A direct current power supply was used to ionize the continuously supplied compressed air, thereby generating a high-temperature flame that ignited the pulverized coal inside the burner for combustion in the furnace. To ensure a successful first ignition of the boiler, the company’s project team, while making every effort to maintain the safe and stable operation of the existing production facilities, broke away from the traditional approach of assigning personnel based on their specific specialties. Following the principle of having multiple skills per employee, they assigned 10 experienced workers and 6 new employees to work together in a mentorship framework. Together, they analyzed the system on-site, created process flow diagrams, and worked on drafting pipeline purging plans, operating procedures, and operation cards. During the project construction process, the project manager instructed the team members to pay close attention to the key milestones, and to carry out tasks such as the inspection of pipeline welding quality, pipeline airtightness tests, one-by-one testing of 3,020 points on each boiler, testing of 482 valves, trial operation of 127 motors, trial operation of equipment in various systems, calibration of boiler air volume, tests of the power plant, boiler pickling, hydrostatic tests, introduction of materials for the utility systems, as well as adjustments related to the three inspections and four determinations and logical interlock functions. All these efforts provided a solid guarantee for the successful ignition of the boilers on the first attempt.
