在电站锅炉运行中,风煤配比是影响经济性的重要参数,但现阶段对风煤配比进行控制主要依靠运行人员的经验。根据输入炉膛的燃料蕴含的化学能以及炉膛内的实际热量,可以得到锅炉风煤配比控制的指导量,以便在锅炉运行过程中进行风煤配比的优化控制。
During operation of power plant boilers, the coal to air ratio, the control of which at present depends on the operator's experience, is an important parameter, affecting the economy of boilers. A guiding coal to air ratio, formulated according to information signals, indicating the chemical energy contained in the fuel, fed into boiler furnace, and the heat released in the furnace, is then to be used during operation for realizing optimized control of the ratio.
