In this embodiment, the distance sensor 15 detects the distance between the burner 5 and the heat exchanger 4 in real time by monitoring the distance from the baffle 16.
Working principle:
the method comprises the following steps of: when the gas flow rate is Q1 to Q2 (i.e., the flame of the burner 5 is a small flame), the distance between the corresponding baffle 16 and the distance sensor 15 is L1 (i.e., the distance between the burner 5 and the heat exchanger 4 when the flame is a small flame); when the gas flow is Q3 to Q4 (i.e., the flame of the burner 5 is a middle flame), the distance between the corresponding baffle 16 and the distance sensor 15 is L2 (i.e., the distance between the burner 5 and the heat exchanger 4 when the middle flame is present); when the gas flow rate is Q5 to Q6 (i.e., the flame of the burner 5 is a middle flame), the distance between the corresponding baffle 16 and the distance sensor 15 is L3 (i.e., the distance between the burner 5 and the heat exchanger 4 when the flame is a large flame).
When the device is used, a user adjusts the first valve 13, when the gas flow value monitored by the flow sensor 12 is in the range of Q5-Q6 (namely, the user needs to adjust the flame to big flame), then an electric signal of the gas flow value is sent to the controller 14, under the action of the controller 14, the driver 104 is controlled to drive the sliding block 102 and the burner 5 to slide upwards or downwards relative to the sliding rail 101 through the threaded rod 103, meanwhile, when the distance between the baffle 16 and the distance sensor 15 is monitored by the distance sensor 15, the driver 104 is controlled to stop running through the controller 14, and the outer flame of the big flame is attached to the bottom of the heat exchanger 4 at the moment, so that the optimal heat exchange efficiency can be achieved under the working state of the flames with different sizes, the utilization rate of heat energy is greatly improved, and the energy consumption and the use cost are reduced.
