Embodiment
[0028] step one:
[0029] Establish a coal-fired real-time coal quality parameter model for the ash conveying system (see the system diagram for details figure 2 ):
[0030] (1) After the coal enters the coal yard, it is piled up according to the type of coal, and the coal parameters of the coal pile are obtained from the incoming coal test:
[0031] Total Moisture M m ;Received base ash A m , the subscript m is the coal pile number
[0032] (2) Introduce a coal-fired online microwave moisture meter on the furnace coal belt, and conduct a secondary measurement of the total moisture of the coal entering each coal bunker: M′ m , and use it to correct the received base ash: A′ m .
[0033]
[0034] (3) According to the real-time coal feeding rate G of the coal feeder corresponding to each coal bunker 1 ~G 6 , the unit is t / h, and the real-time coal-fired parameters entering each coal bunker are obtained from (2), and then the comprehensive dynamic ash characteristic v...
