A New Highlight in Energy Conservation and Emission Reduction—Boiler No. 5 Successfully Put into Operation

On March 17, 2022, Boiler No. 5 successfully completed the 168-hour trial run. During the trial run phase, the boiler operated smoothly, with emission indicators remaining under control, thus achieving the goal of continuous and stable operation.

Boiler No. 5 is a 130 t/h high-temperature separation circulating fluidized bed boiler. Its construction aims to replace the existing medium-temperature separation boiler, thereby improving thermal efficiency, saving energy and reducing consumption, and controlling emission standards. It will also ensure the continuity and stability of the entire large-scale production process and completely resolve any issues caused by the boiler that might affect production.

To ensure the smooth completion of the 168-hour trial run for Boiler No. 5, the company specially organized a special meeting on the trial run, bringing together the Science and Technology Planning Department and relevant departments, and established a trial-run command team. For the numerous issues identified during the purging process, responsibilities were assigned to specific individuals, and each issue was systematically checked and addressed. Based on the feedback from the corrective actions, the final ignition and commissioning schedule was determined.

Since the No. 5 boiler was ignited and brought into steam on March 10, the relevant personnel have remained steadfastly at the site, inspecting the boiler’s operating condition daily, closely monitoring key parameters, and keeping detailed records. For various issues identified during the trial run—such as steam leakage from needle valves, ash leakage from vent holes, and pipe vibrations—they promptly contacted the manufacturer and the installation team for timely resolution, thereby ensuring the stable operation of the boiler.

As of March 17, Furnace No. 5 successfully completed its 168-hour trial run. After seven days of trial operation, the operators have largely familiarized themselves with the operational patterns of Furnace No. 5 and its associated auxiliary equipment. In the next step, under the guidance of the boiler manufacturer, we will further optimize and adjust the combustion conditions of Furnace No. 5. While meeting emission standards, we will strive to achieve greater energy savings and reduced consumption, thereby attaining the specified performance targets and making a solid contribution to Xiangyu Salt Chemical’s “carbon reduction” initiative.
