| Abstract: | The accurate measurement of oxygen content in flue gases is significant for the improvement of the economic combustion. The soft-sensing technique is used to measure oxygen content in flue gases in this paper. Setting up the soft-sensing models of oxygen content through mechanism analysis, and this soft-sensing model fit well with the practical oxygen content, which is illustrated by the simulations. At the same time, the paper states a solution, which attunes the set value of the oxygen percentage based on the boiler's load, then optimizes the rate between air and coal. The practice exhibits the solution's easiness and effectiveness. which increased the combustion efficiency of the boiler notably, saved the coals apparently. |
