Embodiment 1
[0024] An automatic device for firing a heating furnace, comprising a main controller, a first control valve, a second control valve, a circulator and a timer, the main controller is connected with the first control valve and the second control valve, and the inside of the main controller Equipped with a timer and a circulator, the first control valve is set on the east side of the heating furnace, and the second control valve is set on the west side of the heating furnace. The first control valve and the second control valve control the fuel input on the east and west sides of the heating furnace. The first control valve and the second control valve are opened when they are working, and they are kept closed after they stop working, so as to control the combustion state on the east and west sides of the heating furnace. The circulator is connected with the main controller and the first control valve and the second control valve .
[0025] There is a control panel on the main c...
Embodiment 2
[0031] After the main controller inputs the number of cycles through the control panel, it transmits the value to the circulator. After receiving the number of cycles, the circulator controls the number of cycles of the first control valve and the second control valve respectively;
[0032] The circulator control can control the first control valve and the second control valve to work alternately in a cycle. After the first control valve starts to work for 80s, the second control valve starts to work for 80s;
[0033] After the circulator receives the instruction of the number of cycles, it adds one to the number of operations of the second control valve, so that the number of operations of the second control valve is increased by one compared to the number of operations of the first control valve;
[0034] The first control valve and the second control valve control the fuel input on the east and west sides of the heating furnace. The first control valve and the second control...
