The Yulin Coal Chemical Public Engineering Center of Yanjiang Petroleum installs a circulating fluidized bed boiler Author/Source: Shaanxi Yanjiang Petroleum Yulin Coal Chemical Co., Ltd. Date: 2022-04-06 Views: 4 Recently, in light of the actual operations of the center, after careful analysis and research, the Yulin Coal Chemical Public Engineering Center decided to shut down Boiler No. 2 and replace it with Boiler No. 3, a circulating fluidized bed boiler that offers higher operational efficiency and lower energy consumption, thereby achieving cost reduction and improved efficiency. Before the furnace changeover began, under the company’s unified planning and arrangements, various functional departments worked together in close coordination. The managers at the Utility Engineering Center developed a scientific plan for the furnace changeover without disrupting normal production. During the operation period, the operators at the utility center strictly controlled the air volume during the ignition process, and continuously monitored the temperature changes in the boiler while coal was being fed in. They made every effort to reduce steam and water losses as well as fan power consumption. After a day of hard work, tasks such as the fluidization experiment, ignition and temperature rise, coal feeding, and steam integration were successfully completed. The No. 3 circulating fluidized bed boiler was put into operation smoothly, and it has been running steadily to date. It is reported that the 3# circulating fluidized bed boiler at the Public Works Center has advantages over traditional coal powder boilers, including wide fuel adaptability, good load regulation capability, high combustion efficiency, and relatively lower investment and operating costs. Once put into operation, it is expected to be able to burn approximately 7,500 tons of high-sulfur coal per month, saving production costs by over 300,000 yuan and making a positive contribution to the company’s efforts to reduce costs and increase efficiency.
