Calculation of the optimal set value of flue gas oxygen content for the optimization of combustion in power plant boiler;

Computes the optimal flue gas oxygen content and designs combustion controller adopting Loop-shaping to achieve optimization, presents an optimal flue gas oxygen content partial differential equation which takes the minimization net coal consumption rate as the target.

The paper makes an in-depth analysis of the combustion control system in power plantboiler, presents an analysis method of the operation economy in variable operationcondition of the boiler based on the variation of flue gas oxygen content, and then thepartial derivative and micro-increment calculation formulae of the boiler s main thermaleconomy indexes are educed.

This paper presents a kind of soft-sensing method of oxygen content in flue gas based on new generalized predictive control(GPC) algorithm.

The accurate measurement of oxygen content in flue gas of coal-fired power plant has significant meaning for the realization of combustion system’s closed-loop control and optimization running.

The measuring methods of Oxygen-content in flue gases of Coal-fired power plant are analyzed.

On-line combustion optimization of power station boiler based on the soft sensing of oxygen content;
