Embodiment approach
[0147] According to the second embodiment of the present invention, a method for monitoring and controlling the combustion of residual carbon in the cooling process of hot sintered ore is provided:
[0148] A method for monitoring and controlling the burning of residual carbon in the cooling process of hot sinter or a method for monitoring and controlling the burning of residual carbon in the cooling process of hot sinter using the above-mentioned device for monitoring and controlling the burning of residual carbon in the cooling process of hot sinter, the method includes the following steps :
[0149] 1) The device starts to operate, and the first temperature measuring device 5, the first flow detecting device 6, the oxygen concentration detecting device 23, the second temperature measuring device 7 and the second flow detecting device 8 monitor the temperature, flow and oxygen concentration of the circulating gas in real time , wherein the first temperature measurement devic...
Embodiment 1
[0225] like Figure 1-2 A device for monitoring and controlling residual carbon combustion in the cooling process of hot sintered ore, which includes a vertical cooler 1, a waste heat boiler 2, a dust collector 3 and a circulating fan 4. According to the flue gas flow direction, the high-temperature gas outlet 102 located on the upper part of the tower wall of the vertical cooler 1 is connected to the air inlet 201 of the waste heat boiler 2 through the first pipe L1. The second pipeline L2 drawn from the air outlet 202 of the waste heat boiler 2 is connected to the low-temperature gas inlet 101 located at the lower part of the tower wall of the vertical cooler 1 via the dust collector 3 and the circulating fan 4 . The low temperature gas inlet 101 communicates with the air supply device 103 at the bottom of the tower body of the vertical cooler 1 . The device is provided with a first temperature measuring device 5 , a first flow rate detecting device 6 and an oxygen concentr...
