The First Boiler at WeiHua Company Gets a \"Smart\" Upgrade Author/Source: WeiHua Group Date: 2021-03-03 Clicks: 26 On February 16, the intelligent optimization and energy-saving renovation project for WeiHua Company’s No. 2 boiler completed a 72-hour performance test; the automation rate of all control circuits was 100%. The coal consumption per ton of steam produced by the boiler decreased by 1.2%, while the consumption of denitration agents and desulfurization agents dropped by 5.6% and 10% respectively, meeting all the intended goals of the renovation. This marks a milestone achievement in Weihua Company’s project to intelligently optimize and save energy in its boilers, representing a solid step forward in the company’s efforts to fully realize an \"intelligent factory\" as well as to make progress during the \"Year of Efficiency Improvement 2021\". The intelligent optimization and energy-saving renovation of Boiler No. 2 this time employs a general combustion optimization control technology (abbreviated as BCS). Compared with the original control system, BCS optimal control has three main advantages. The first is automated control. Through the BCS system, this renovation achieved full automation of 9 control loops, including boiler load, main steam temperature, deaerator pressure, and level. To date, all the main control circuits of the steam-water system, combustion system, and desulfurization and denitrification systems in Boiler No. 2 have been automated. The second is intelligent adjustment. Through extensive data analysis and tuning, the BCS system monitors boiler operation parameters in real time to make optimized adjustments. Boiler operators vividly describe it as an “untiring stoker” – one that is not affected by external conditions or emotional fluctuations, and focuses on optimizing operational parameters, thus perfectly embodying the work motto of “devote 60 seconds of careful effort for every minute spent on duty”. Third is refined operation. Optimal wind-coal ratio, optimization of boiler combustion control ； The most appropriate addition of desulfurization and denitration agents ensures the economic and stable operation of the boiler’s environmental protection systems. By keeping the main parameters of the boiler within the optimal economic operating range for an extended period, the operational quality of the plant is greatly improved, while raw material consumption and the workload of the staff are reduced. In terms of safe operation, the voice alarm function of the BCS system enables operators to be promptly informed of abnormal parameter values, ensuring that they can accurately assess the operating conditions right away ； At the same time, the operator can, in response to changes in operating conditions, promptly disable or activate the optimization control system to ensure the continuous stability of the operating conditions. In terms of economic operation, through intelligent optimization control, various consumption indicators of the boiler are significantly reduced, resulting in good energy-saving and economic benefits. The intelligent optimization and energy-saving renovation project for Coal Powder Boiler No. 2 was completed successfully. It represents an important step in the company’s efforts to achieve full automation in its manufacturing processes, as well as a practical effort to promote the high-quality transformation and development of the enterprise. The success of this renovation has provided valuable experience for the application of intelligent optimization techniques in subsequent installations. Going forward, the company will build on the successful results achieved with Boiler No. 2 to implement these techniques across all boilers at the Binzhou facility, thereby advancing the development of the intelligent factory project at the Weihua Binzhou Company.
