The method and apparatus for real-time measuring the coal consumption of unit electric generator set in steam-electric power plant are disclosed. Its measuring method includes to measure the ash content (A) and water content (W) of coal fuel, supplied coal amount (B), and the power of electric generator, and to imput them to computer, where the coal consumption rate of unit electric generator set is calculated (b=BxQd/NxQs). Said apparatus includes ash measurer, water measurer, metering unit of coal supply and powermeter, and is connected via photo-electric isolator and A/D converter to computer, where data processing, calculation, display and printing are performed. When coal consumption exceeds its threshole, sound and light alarms are sent. |
