The running characteristics of marine auxiliary boiler burning control system is analyzed. The construction of optimizing model to marine auxiliary boiler burning control system and the solution of the optimizing model, the control regulation of marine auxiliary boiler real-time burning system are discussed. A control method is introduced that combines classical PID control and optimal control. The parameters of the marine auxiliary boiler burning control system is optimized by construction of the relationship model between the amount of spray oil, amount of sending wind, amount of pilot wind, steam rate of flow to steam pressure, the oxygen content and the negative pressure of furnace.
