Energy-saving optimization of the gas-fired boiler by DOE method

The boiler consumes a lot of energy in the process of operation. Therefore, how to reduce the energy consumption of the boiler is the key to energy saving and emission reduction. The gas-steam ratio of the boiler is an important index to measure the boiler operation efficiency. Thus, in view of the present situation of the gas-steam ratio, the main influencing factors of the boiler steam-gas ratio are determined through comprehensive analysis and on-site argumentation. Then, the boiler operation parameters are optimized by using the experimental design method (DOE), and the optimization effect is verified. The results show that after taking corresponding measures, the gas-steam ratio is reduced by 7.7% compared with the same period last year. Its stability is also improved.
